摘要
Abstract
With the continuous decrease in gas concentration during coal mining and the introduction of new national policies,low-concentration gas has been widely utilized in gas generator units.The power generation efficiency of gas generator units accounts for about one-third of the gas combustion energy,leaving 47%of residual heat energy from high-temperature water and exhaust gases.Failure to utilize this heat effectively would result in significant energy waste.The Duanhe Low-Concentration Gas Power Station has comprehensively designed a waste heat utilization system for the generator units.The recovered heat is used to address issues such as building heating,shaft lining anti-freezing,and hot water supply for bathing in the mining area.Additionally,the waste heat system was employed to upgrade the existing air intake devices within the station.Achieving a plate heat exchanger utilization rate of up to 80%,improving the success rate of unit startup and ensuring stable operation.Upon completion,the project generates an annual revenue of 4.34 million yuan and increases profits by 4.494 million yuan.关键词
