Through the days of this scene, everything in the world is difficult.

With such a poem, describe the current Huaneng Anyuan power plant, appropriate.

Panorama of Huaneng Anyuan Power Plant

A few days ago, Huaneng Anyuan Power Plant's new construction project of "high pressure and small pressure" won the 2016-2017 National Quality Engineering Gold Award, which is the second coronation after the project won the 2016 National Power Quality Engineering Award. The National Award of high quality engineering is confirmed by the Central Committee of the Communist Party of China and The State Council, which is the earliest established in the field of engineering construction and the highest specification, cross-industry and cross-professional national honor award. It is the highest honor award in the quality of engineering construction in China, and the gold award of high quality engineering is one of the "laurel", which represents the international leading level.

This honor is a reward for the spirit of "dedication, pioneering and innovation", and the highest praise for the "pursuit of excellence and the creation of classics".

As the first secondary reheat power plant in China and the first national Gold Award project in Jiangxi Province, Huaneng Anyuan Power Plant is the first in China to realize the application of secondary reheat technology in the field of coal power. Its emission, energy efficiency and other indicators have reached the world-class level, and it is the first in Jiangxi Province to pass the national ultra-low emission acceptance of coal-fired units. The standard coal consumption of power supply is 275.2 grams per KWH, which is about 16 grams per KWH lower than the average level of the same type of primary reheating units in China, and the annual fuel cost can be reduced by about 163 million yuan. Since it was put into operation, it has generated 9.06 billion KWH of electricity and paid 493 million yuan of tax. It sets a new benchmark for China's coal power industry and drives 22 newly built units in China to adopt the secondary reheating technology. It has become the first demonstration area of ecological civilization construction in Jiangxi Province, and the "pioneer" of creating the "Jiangxi model" of beautiful China.

Energy efficiency indicators leading in China

Make concerted efforts to overcome difficulties, and eventually achieve a great cause and create brilliant

Every time looking back at the past life of Huaneng Anyuan Power Plant, it is a time to review the pioneering process of vigorous merchants.

Huaneng Anyuan Power Plant was founded in 1958 as Pingxiang Power plant in Jiangxi Province. In 2008, it joined China Huaneng Group Corporation, the top five power generation groups in China, and became a member of Huaneng Red Series power plants. In order to support the construction of Jiangxi old revolutionary base area and practice the development concept of "innovation, coordination, green, openness and sharing", Huaneng Group shut down all the small units in the original Xiangdong factory in December 2011, and decided to invest 5.334 billion yuan in September 2012 to change the location of Huaneng Anyuan Power Plant to Luxi. It took the lead in building two 660,000 kW ultra-supercritical secondary reheating units in China.

Secondary reheating, the world's leading power generation technology, is known for its complexity and particularity, and has been a "crab" that no one dares to eat in the domestic power industry. While China is still debating whether to promote the application of this technology, on June 28, 2013, Huaneng took the lead in silence and started construction of China's first second reheat power plant in Huaneng Anyuan Power Plant. In June and August 2015, two units were successfully put into production, and the first "crab" was finally consumed by Huaneng. Become a milestone project of developing efficient clean generating set in China.

The sails are galloping, and the waves of the sea are harmonizing. Through a time node, Huaneng Anyuan power plant along the way sonorous. This electric pioneer, since its groundbreaking day, is destined to become a monument in the history of Chinese electric power.

He who desires together wins. Huaneng Anyuan Power Plant has turned from a blueprint into a vivid reality, full of selfless support and help from governments at all levels and related departments and units. It carries the mission and vision of Huaneng people to build a "red, green and blue company".

-- All parties have come to the rescue with real strength. The main leaders of the provincial Party Committee and government have been to the National Development and Reform Commission and Huaneng Group for many times to coordinate the project approval and implementation, and have been to the site for many times to help solve problems. Major leaders of Provincial Development and Reform Commission and Provincial Energy Bureau went to Beijing to implement project approval and other work; The provincial Environmental protection Department, water resources Department, safety supervision bureau, archives bureau, fire brigade and other departments to the site for many times to guide the environmental protection, water protection, fire protection, labor protection, occupational health, archives acceptance work, for less than a year in the production of the completion of the special acceptance to provide a powerful help; The leading Group Office of provincial key project construction and promotion arranges special personnel to coordinate the construction of special railway lines of the project. Nanchang Railway Bureau vigorously coordinates the optimization of special railway lines and the opening procedures, which provides strong support for the timely opening of special railway lines. State Grid Jiangxi Electric Power Company has given strong support from the construction of delivery project, unit commissioning and operation load dispatching, etc. Pingxiang Municipal Party Committee, the main leaders of the project to promote, mobilize all resources to ensure the orderly and rapid progress of the project; Luxi County also set up a special "Huaneng Coordination Office", docking service project construction, for the maintenance of a good external environment has done a lot of work.

-- Self-reliance and high quality. Huaneng Group has set up a "Secondary reheating Technology Leading Group" to provide technical support for the project. Huaneng International has selected a number of excellent management talents and skilled personnel from the whole company, and selected domestic first-class construction team to escort the whole project. Huaneng Jiangxi Branch has assigned leaders to guide project construction and excellence.

Factory prosperity I honor, factory failure I shame. Andian people carry forward the "thousands of words, thousands of hardships, leave no stone unturned" spirit of professionalism, to achieve the second take-off of the enterprise. During the construction period, as long as there is construction on site, there are electricity safety personnel on site to supervise safety, quality and coordination issues. For them, there is no concept of commuting or holidays.

During the commissioning period, branch leaders, factory leaders 24 hours on-site command; Party cadres dare to take responsibility, major key operations, leading the charge in the front.

After put into operation, in order to test the boiler insulation effect, maintenance personnel specially "to test the temperature", specially pick the highest temperature for detection. In order to reduce energy consumption, the operators held Zhuge Liang meetings for many times to offer suggestions. Through fine debugging and optimizing the operation mode, the unit ran safely, stably and efficiently.

In the spring of 2016, there was continuous rain, and the vegetation restoration of the plant was slow. The young volunteers of the plant took immediate action to organize voluntary tree planting, and the vegetation was restored as scheduled. There was a shortage of manpower for the project archives sorting, so the new college students volunteered to participate in the file filing and entry work, and passed the "help" for the special acceptance of soil and water conservation and archives on time. "Many people add wood to the fire" in Huaneng Anyuan power plant has been a vivid interpretation.

Stepping stone to leave imprint, grasp iron mark, innovation management cast gold

With great foresight, Huaneng Group clearly required Huaneng Anyuan Power Plant to "build a world-class secondary reheating demonstration power plant and create a national Quality Project Gold Award" in the approval of the project commencement. Over the past 3 years, we have never forgotten the great trust of the group company, and persevered with the strength of leaving imprint on the stepping stone and grasping the mark on the iron. We have forged ahead towards the set goal by doing well and achieving good results, and created a set of unique, replicable and popularizable project management mode.

-- Persisting in forward-thinking, striving for scientific and technological innovation and engineering excellence. As early as the construction preparation stage, Huaneng Anyuan Power Plant has written the goal of creating national excellence and gold award into all project bidding and contract documents, and compiled a package of guiding documents for excellence creation, forming a working atmosphere of "everyone has indicators and everyone has responsibilities". The whole process of the project carries out fine management, comparing with more than 350 national excellent gold award projects, tens of thousands of specific standards and indicators to grasp the project management, and accept the supervision and inspection of the "whole-process quality control demonstration project" of the China Electricity Construction Association. After the unit was put into operation, Zhang Jianlin, general manager of Huaneng Jiangxi Branch, personally arranged a meeting to promote the excellence of Huaneng Anyuan Power Plant, and pointed out that "Huaneng Anyuan Power Plant should take the National Excellence Gold Award as the starting point, improve the lean management level of the enterprise, and lay the foundation for the establishment of a 660,000 kW energy efficiency benchmark unit in China".

"God pays off those who take care of themselves." Because it is the first secondary reheating unit, there is no experience to learn from. The very common problem in conventional thermal power construction may be a big problem in the construction process of secondary reheating unit. Therefore, every step should be taken with caution. In order to break through a series of key technical problems of secondary reheating, such as steam temperature regulation and coordination control mode, Huaneng Group has established a leading group of secondary reheating technology research to focus "firepower" on more than 10 key technical topics. After subject theory, commissioning practice, in the domestic first application based on predictive control, neural network adaptive technology case INFIT control system such as a variety of thermal control methods, with the most rigorous domestic boiler wall temperature monitoring system, for a unique set of "combination", effectively prevent the limit parameters of boiler heating surface nearly overtemperature, It improves the rapid corresponding capacity of the unit load and provides a strong guarantee for the safe and reliable operation of the unit in the whole life cycle. Finally, the "blue" power plant, which is driven by innovation, created 3 new world records, refreshed 13 domestic records, won 15 patents and 11 science and technology progress awards at the provincial and ministerial level and above, and 3 achievements were released at well-known international conferences in the industry, which made the industry sit up and take notice.

-- Work safety and environmental protection. The devil is in the details. Walking into Huaneng Anyuan Power Plant, safety warning signs such as "safety is the first responsibility, the first work, the first benefit" can be seen everywhere. More THAN 400 fire FIGHTING BOXES AND 5 SETS of special FIRE fighting SYSTEMS ARE ON DUTY 24 HOURS a day. The identification of fire fighting facilities, the person in charge and the date of inspection are clear. In Huaneng Anyuan Power Plant, safety production has become an important "four-dimensional pillar" of the enterprise. Safety awareness has been integrated into the blood of all staff, and the company has maintained zero record of safety accidents in production and operation since construction.

As early as the beginning of construction, huaneng AnYuan power plant construction peak construction personnel up to more than 5000 people, a special type of work staff of nearly one thousand people, large lifting equipment has more than 40 units, aerial work, limited space homework, crossover operation is frequent, compact and plant design, construction site is limited, so large and complex construction site, safety production task difficult and onerous. Huaneng Anyuan Power Plant has prepared for the future by establishing rules and regulations to "nip in the future". Starting from the aspects of design and calculation, construction plan preparation and measure layout, combined with the characteristics of thermal power construction, such as deep cross operation and high temperature and high pressure equipment, "six red lines" and two "ten inaccuracy" have been formulated for safe production. To achieve the safety system, safety measures, safety supervision, safety rectification of the "seamless" docking, the safety of the hidden dangers "catch all". During the construction period, 102 safety inspections of various types were organized, and 1,950 problems were found, with an improvement rate of 100%. Huaneng Anyuan power plant safety system of the whole, the strict, let the people to marvel at, even always harsh, and accustomed to "find a bone in the bone" of the National Energy Administration, Central China electricity regulatory Bureau, provincial energy bureau leaders and experts to the site inspection, have given a high evaluation.

No diamond, no porcelain work. Electric safety personnel clearly realize that: the unit construction is good, but also good operation, in order to give full play to the advantages of efficient cleaning secondary reheating unit. From an old factory into obsolescence and closure, transformed into the "first home" of the new factory, talent is undoubtedly related to the survival and development of the enterprise "life door". Huaneng Anyuan Power Plant attaches great importance to the cultivation of talents, and carries forward the pioneering spirit of "opening the way to the mountains and bridging the water; The enterprising spirit of asking for the gap and self-pressuring; Dare to be the first, dare to be not innovative spirit ". After the closure of the old unit, the power installation staff is not dependent on the dependence, self-reliance, through undertaking the daily maintenance, overhaul, commissioning, operation of other power plants, "with the operation of training" and "with the inspection of training", the staff has experienced new skills in practice. Operating personnel adopt the way of introduction to go out, teaching in accordance with their aptitude to carry out theoretical training, imitation machine training, similar to the power plant apprentice practice, to create a growth of knowledge, exercise courage of the "new force". In the stage of unit installation and commissioning, production staff got involved in the field in advance to recognize the equipment, participate in the commissioning, compile the system drawing and operation rules, realize the seamless connection between infrastructure and production, and find out a set of mature operation technology of the secondary reheating unit.

Now more Benedict Lingyunzhi, don't teach ice Jian negative original intention. Huaneng Anyuan Power Plant, as the "red" power plant of Huaneng, adheres to the responsibility of a central enterprise and is committed to building a "green" power plant that pays attention to science and technology and protects the environment. Nearly 800 million yuan (15.23% of the total investment) has been invested in the construction of advanced environmental protection facilities that are far stricter than the national ultra-low emission standards approved by the Ministry of Environmental Protection. After the operation, the emission concentration of air pollutants is far better than the national ultra-low emission standard, and enjoys the "dividend" of the national ultra-low emission electricity price policy.

-- Adhering to leading standards and grasping project quality and performance indicators. Preparation makes success, and unpreparedness makes failure.

Huaneng ANYUAN Power Plant GRASPED the leading ROLE of engineering optimization design, from determining the preliminary design principles to the construction drawing design, strictly implementing Huaneng's optimization design principles, and vividly implementing the two-type power plant construction concept of "resource saving and environment friendly" in the whole process. Jiangxi Electric Power Design Institute, the engineering design unit, firmly grasps the three focus points of "efficiency, reliability and environmental protection", overcomes the constraint of almost blank domestic secondary reheating technical data, draws on the "rocks from other mountains" in related fields abroad, and uses PDMS three-dimensional technology. It has adopted 10 national key energy-saving and low-carbon technologies, 44 "Five new electric power" technologies, 10 independent innovation and research and development technologies, and carried out 76 fine designs. It has become a master of scientific and technological innovation, and its engineering design has won the first prize of outstanding design achievements of national engineering construction projects.

Quality is the lifeline of the project, the source of the quality of the project construction, also let the unit "namely profit" win on the starting line. From the beginning to the end, Huaneng Anyuan Power Plant HAS put project quality first, established a perfect quality assurance system, and formulated a total of 63 quality management systems and standards. By controlling the source, grasping the process, retesting, strengthening the process supervision, moving the gate forward, the establishment of strict drawing review, equipment supervision, regular quality supervision and inspection system; The whole process of fine management, focus on the process of excellence, through the "sample guide, example drawing demonstration", set the construction process standard legend in each construction point, the construction personnel are required to master the standard, the construction of the standard; On-site strict implementation of the "three-level inspection, four-level acceptance" system, the last process did not pass the acceptance, is prohibited to enter the next process. By vigorously promoting new technology, improve the quality of engineering process, key parts of the project, key parts, parts prone to quality problems, set up a QC team, to solve the process quality problems encountered in the construction process. The main outlet steam pressure of the secondary reheating unit boiler in Huaneng Anyuan Power plant is 32.45 mpa, and the outlet steam temperature of the primary and secondary reheaters is 623℃, which is the highest parameter in the world. The construction technical requirements and standards are very high, and its success is a great challenge to engineers. After more than 20 experiments, the welding QC team of Jiangxi Thermal Power Construction Company has solved the world-class technical problem of welding and heat treatment of P92 martensitic steel with high temperature super-wall thickness.

On August 21, 2014, a P92 martensitic steel welding joint with a wall thickness of 160 mm, the largest in China, was successfully welded after the continuous work of 6 technicians for 84 hours and the 200 kg electrode was used. According to statistics, a total of 136,532 monitored welds in the two units are more than 30,000 welds in the conventional units. During the trial run and after production, no boiler tube explosion due to welding quality has affected the production. The whole project 178 unit engineering all once accepted. The key nodes of unit installation, experiment and debugging were all successful once. The overall project quality was evaluated by the third party as high quality excellent project.

-- Adhering to problem-oriented progress. As THE FIRST ULTRA-SUPERCRITICAL SECONDARY REHEATING PROJECT IN China, DESIGN, equipment manufacturing, construction and installation are all new topics.

The foundation is not strong, the earth shakes. Feeling this, Ann electric people know that "there is no security and to the two progress is meaningless." Huaneng Anyuan Power Plant is busy without fuss. It has achieved no rush, no change in target and no drop in standard. Through scientific organization, careful planning to ensure the construction period, for this reason, the establishment of a strict construction scheme review system, the preparation of the "construction organization general design" need to be reported to the superior company for review and approval, clear time node. Before the construction, the construction units according to the "construction organization design" to prepare the specific construction plan, and strive to the construction plan orderly and efficient, scientific and reasonable not repeated, encountered problems are predestined. In the construction process, various factors affecting the progress should be predicted in advance, and the construction, design, supervision and construction units should jointly confirm the feasibility of factors such as resources, environment and safety that affect the construction period. Through scientific management, reasonable arrangement and coordination, the first secondary reheat power plant in China was built on schedule.

High push, half the effort twice the result. In each key stage of the project construction, CAO Peixi, general manager of Huaneng Group, Liu Guoyue, deputy general manager and general manager of Huaneng International, and other major leaders worked on site, and some key and difficult problems in engineering, technology and project organization were readily solved. Zhou Liang and Zhao Jianyong, two deputy general managers of Jiangxi Branch, took root in the construction site. In the face of the serious lag of the progress of the railway special line, Zhong Mingcai, then the factory director and now the deputy general manager of Jiangxi Branch, actively lobbied all parties to promote the construction of the railway special line as soon as possible, ensuring the smooth progress of the project as a whole.

Don't say this spring will end, next year spring times people. Facing the wind and thunder of The Times, and with the rhythm of The Times, a new round of development planning like a Rurafter giant pen, depicts a magnificent and magnificent endeavor picture for Jiangxi, creating a beautiful China "Jiangxi model" grand idea will become a magnificent and beautiful reality. Huaneng Anyuan Power Plant fully implements the national energy strategic policy of "saving, cleaning and safety", stays true to its original aspiration, and continues to forge ahead towards creating a national benchmark unit with 660,000 kW energy efficiency. It will surely cut through waves and sail to a more brilliant future!
