工业尾气内燃机发电技术通过回收钢铁、化工等行业的可燃尾气实现清洁能源转化，江苏科霖源作为国内燃气内燃机发电领域的领军企业，技术应用案例为碳减排提供了重要示范。

　　The industrial exhaust gas internal combustion engine power generation technology achieves clean energy conversion by recycling combustible exhaust gases from industries such as steel and chemical. As a leading enterprise in the domestic gas internal combustion engine power generation field, Jiangsu Kelinyuan's technology application case provides an important demonstration for carbon reduction.

　　01碳减排的核心机理

　　01 Core mechanism of carbon reduction

　　1.替代化石燃料，减少直接碳排放

　　1. Replace fossil fuels and reduce direct carbon emissions

　　科霖源的大功率燃气内燃机（如NPG4000型，4000kW）可将焦炉煤气、高炉煤气等工业尾气直接转化为电能，替代传统燃煤发电。

　　Kelinyuan's high-power gas internal combustion engine (such as NPG4000, 4000kW) can directly convert industrial exhaust gases such as coke oven gas and blast furnace gas into electricity, replacing traditional coal-fired power generation.

　　2.避免直接排放

　　2. Avoid direct emissions

　　采用“湿法+生化脱硫技术”，科霖源解决了兰炭气、沼气等气体中的硫化物污染问题。该技术通过含好氧菌的碱性溶液吸收有机硫，脱硫效率高且运行成本低，已在山西、河北等地化工企业成功应用，污染物排放可降至10mg/Nm?以下。

　　By adopting the "wet process+biochemical desulfurization technology", Kelinyuan has solved the problem of sulfide pollution in gases such as orchid charcoal gas and biogas. This technology absorbs organic sulfur through alkaline solutions containing aerobic bacteria, with high desulfurization efficiency and low operating costs. It has been successfully applied in chemical enterprises in Shanxi, Hebei and other places, and pollutant emissions can be reduced to 10mg/Nm? following.

　　3.热电联供提升能效

　　3. Combined heat and power supply improves energy efficiency

　　内燃机发电余热可进一步用于生产蒸汽或供热，综合能源利用率可大大增加，也可减少额外能源消耗。

　　The waste heat generated by internal combustion engines can be further used for steam production or heating, greatly increasing the comprehensive energy utilization rate and reducing additional energy consumption.
