] On August 31, Daqing Refining & Chemical Company focused on the actual operation of its boiler units, optimized their performance, improved relevant processes, and explored ways to reduce costs and increase efficiency; as a result, the overall energy consumption of these boiler units decreased by 4% compared to the previous year.   Focus precisely on operational optimization. Daqing Refining & Chemicals actively adjusts its fuel mix to reduce fuel consumption, thereby lowering fuel costs while also cutting nitrogen oxide emissions and achieving a win-win situation in terms of economic and environmental benefits. At the same time, turbine No. 3 is activated to efficiently recover low-pressure steam, thereby reducing energy losses that occurred previously due to the direct release of such steam.   Strive for excellence in operational details. Daqing Refining and Chemicals exercises precise control over furnace combustion; by optimizing air distribution and maintaining stable combustion, it adjusts the air and flue gas systems in real time to ensure a steady supply of medium-pressure and low-pressure steam, optimizes control of the oxygen level in the furnace, further reduces heat losses from flue gases, and improves the overall thermal efficiency of the boiler.   Seek breakthroughs in technological transformation. Daqing Refining & Chemical has carried out research and development efforts on the key components of boilers, focusing on the renovation and upgrading of boiler temperature reducers. The original surface-type temperature reducers were replaced with spray-type ones, which reduced the flue gas temperature from 180 to 200 degrees Celsius to around 140 degrees Celsius, thereby effectively minimizing heat losses from the flue gases. Since the beginning of this year, Daqing Refining & Chemical has carried out more than 10 innovation projects to help improve quality and efficiency.
