工業(yè)尾氣內燃機發(fā)電技術通過回收鋼鐵、化工等行業(yè)的可燃尾氣實現(xiàn)清潔能源轉化，江蘇科霖源作為國內燃氣內燃機發(fā)電領域的領軍企業(yè)，技術應用案例為碳減排提供了重要示范。

　　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碳減排的核心機理

　　01 Core mechanism of carbon reduction

　　1.替代化石燃料，減少直接碳排放

　　1. Replace fossil fuels and reduce direct carbon emissions

　　科霖源的大功率燃氣內燃機（如NPG4000型，4000kW）可將焦爐煤氣、高爐煤氣等工業(yè)尾氣直接轉化為電能，替代傳統(tǒng)燃煤發(fā)電。

　　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“濕法+生化脫硫技術”，科霖源解決了蘭炭氣、沼氣等氣體中的硫化物污染問題。該技術通過含好氧菌的堿性溶液吸收有機硫，脫硫效率高且運行成本低，已在山西、河北等地化工企業(yè)成功應用，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.熱電聯(lián)供提升能效

　　3. Combined heat and power supply improves energy efficiency

　　內燃機發(fā)電余熱可進一步用于生產蒸汽或供熱，綜合能源利用率可大大增加，也可減少額外能源消耗。

　　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.
