　　 As a former veteran employee of Jilin Chemical Fiber, I was excited to learn that Su Lei, the director of Jilin Qifeng Chemical Fiber Co., Ltd. Power Branch under Jilin Chemical Fiber, was awarded the 2025 National Model Worker. I was deeply shocked by his many highlights, and my admiration also rose quietly in my heart.

　　 Carps leap over the dragon gate, and work hard to shine

　　 Through video connection, I finally "met" Sulei. It was noon. He was dressed in clean and tidy work clothes, of medium stature. Although he was not over 40 years old, his face was mature and stable beyond his age. Such a seemingly ordinary person has cut through the thorns in his 13 year career, growing from a front-line maintenance worker to a senior mechanical engineer and a professional and technical leader in public works.

　　 He spoke calmly and said slowly: "I have been working in the power plant. Ensuring the stable operation of the system is the top priority. How to generate more power is the core of our daily meditation. Our chemical fiber group's cogeneration power plant is responsible for supplying water, electricity and steam for the group's production. The core of my work is to focus on efficient output, strive to generate more electricity at a faster speed and in a more economical manner, and use the least steam to generate the most electricity. Among them, the primary task is to ensure the stability of equipment and improve its stability; Secondly, reasonably adjust the number of operating equipment to ensure that all steam is used for power generation. At the same time, it is necessary to extend the boiler operation time, make the unit operate stably, and tap the boiler operation efficiency. "

　　 When talking about the transformation of circulating fluidized bed boiler, his eyes suddenly became focused and firm: "The circulating fluidized bed boiler is prone to wear, which leads to the problem of four tube leakage, which once made me sleep and eat hard. To solve this problem, we deeply analyzed, grasped the root causes of the contradiction, and first started with adjusting the raw coal structure to reduce wear as much as possible; And optimize the air coal ratio to make it more stable and reasonable, so that the flow and pressure of coal in the furnace are more stable. Not only that, we also need to take precautions, make efforts from the level of active defense of equipment, and abandon the practice of passive defense. After in-depth demonstration, we have adopted anti-wear networking technology to enhance the wear resistance of the inner wall of the furnace, standardize the use of pouring materials, make it more in line with the actual needs, and effectively improve the operation time of the boiler. In terms of equipment maintenance, I started from personnel training and carried out work in strict accordance with the site management standards. We are also constantly exploring the rules, distributing according to the seasonal changes and gas demand, and configuring different units according to the gas consumption, so as to maximize the efficiency of each ton of steam power generation. "

　　 For many years, he has been working around the smooth operation of the unit and the maximum utilization of steam to ensure the orderly production. Relying on the thinking of challenging the extreme cost reduction, he has constantly explored the efficiency of water, electricity and steam system elements, improved the utilization rate of resources and energy, and completed more than 200 technical breakthroughs such as "improving the efficiency of power generation per ton of steam". In the past five years, the factor efficiency of the hydropower and steam system has increased significantly by 22%, 35% and 43% respectively, with a cumulative effect of 520 million yuan, and a profit contribution rate of 18.5% for the group company, which has strongly promoted the company's green development.

　　 Unlimited challenge, innovation and new journey

　　 Sulei devotes himself to innovation and is committed to providing reliable power supply for the Group's production. The process of his constant deepening of the innovation driven path is undoubtedly his magnificent poem dedicated to youth. "Innovation never ends", this sentence appropriately explains his work philosophy.

　　 He gave full play to his professional and technical advantages, constantly made breakthroughs in innovation and supply assurance, and opened up a new path in the traditional path. Through the integration and optimization of three 66 kV high-voltage substations outside the plant, the power supply capacity has increased by 134%, laying a solid foundation for the cluster power supply of the carbon fiber industry chain. At the same time, with the help of optical fiber communication technology, the substation data status protection monitoring was completed, and the high-voltage substation was successfully unattended. In addition, he actively introduced external resources, widened the supply guarantee channel, and added 190t/h steam to Songhuajiang Power Plant and Baohe Coal Industry, which increased the total steam supply capacity from 1180t/h to 1370t/h. Through the innovation and transformation of the filter tank and large well system of the first water plant, the efficiency of the old facilities has been improved, the water production capacity has been increased from 1800t/h to 2000t/h, two water collecting wells and one water intake bucket head have been newly built, and the new water intake capacity is 3200t/h, which provides strong support for the incremental demand for hydropower and steam of the group company.

　　 Su Lei is good at breaking inertial thinking, daring to break through the shackles of traditional cognition, and breaking through difficult problems in difficult situations. In view of the key cost factors, he deeply explored the various links of raw coal "mining, storage, distribution and combustion". Purchase coal at a low price by studying and judging the market law; According to the nature of different coals, they shall be stored in layers to prevent card dropping and spontaneous combustion; According to the boiler characteristics, the coal blending principle is formulated to improve the combustion efficiency of raw coal and effectively reduce the comprehensive unit price of raw coal. In order to solve the problem of boiler heat exchange efficiency, he changed 1 #, 2 # and 5 # boiler surface desuperheaters to hybrid desuperheaters, saving 97 kWh per hour, reducing the exhaust gas temperature by 8 - 10 ℃, and increasing the boiler thermal efficiency by 0.5%. By optimizing the flow structure of the steam turbine and increasing the inlet steam flow, the generating capacity of the unit has increased by 10%, and the power generation index per ton of steam has increased by 9% in five years, creating an annual efficiency of 30 million yuan, setting a new record for power generation in history.

　　 Practising green development, taking responsibility and showing feelings

　　 Sulei always adheres to the awareness of environmental protection red line, actively promotes the concept of green and low-carbon development, and protects the green background of enterprise development while sticking to the bottom line. In order to solve the problem of high combustion temperature of the second phase boiler and the difficulty of handling nitrogen oxides, he studied the relationship between the boiler temperature field and the production of nitrogen oxides, carefully optimized the transformation scheme of denitrification equipment, and successfully made the flue gas of the second phase boiler reach the ultra-low emission standard.

　　 He is like a ceaseless Endeavor. He tackles one problem after another, adheres to the belief that "we are in front of the problem, and there is no problem in front of me", and creates new miracles one after another with wisdom and painstaking efforts. In view of the characteristics of acrylic fiber wastewater, he led the research team to put forward the scheme of combining pretreatment, biochemical treatment and advanced treatment for new sewage after repeated tests and exploration, effectively removing pollutants in sewage and improving sewage treatment capacity by 20000 tons/day. The effort pays off. Su Lei is fulfilling his promise step by step with his actual actions. He has been awarded provincial and municipal model workers successively. In 2023, he was rated as the top class model worker in Jilin Province, and this year, he won the title of national model worker.

　　 After the interview, I racked my brains for the title of the article. After all, the title is the eye of the article. When I added Su Lei's WeChat, his WeChat name "Running Snail" inspired me, and I suddenly understood. Isn't this a vivid portrayal of Su Lei's work? He seems to be moving slowly like a snail, but on the road of pursuing progress and innovation, he never stops, runs hard all the way to higher goals, and constantly writes his own extraordinary chapters.
