頁巖油、蘭炭、焦炭、電石、鐵合金等煉化生產企業(yè),在生產過程中會伴隨產生大量的低熱值工業(yè)尾氣。這些可燃氣體成分以氫氣、一氧化碳為主,成分復雜、雜質多、成分不穩(wěn)定、毒性大、易燃易爆,除小部分煉化工廠自用外,剩余大部分燃燒排空浪費。
Refining and chemical production enterprises such as shale oil, blue coke, coke, calcium carbide and ferroalloy will produce a large amount of low calorific value industrial tail gas in the production process. These combustible gases are mainly composed of hydrogen and carbon monoxide, with complex composition, many impurities, unstable composition, high toxicity, flammability and explosion. Except for the self-use of a small number of refining and chemical plants, most of the rest are burned and exhausted.
針對此類氣體,以燃氣內燃機為基礎,開發(fā)了適用于焦爐煤氣、發(fā)生爐煤氣、蘭炭尾氣、油頁巖尾氣、電石尾氣、鐵合金尾氣等多種工業(yè)尾氣的大功率燃氣發(fā)電機組,功率范圍500-1200kW。將這些可燃焦爐煤氣發(fā)電利用變廢為寶, 既解決了排放對空氣的污染,又可節(jié)約電力資源。
For this kind of gas, based on the gas internal combustion engine, a high-power gas generator unit with a power range of 500-1200kW has been developed, which is suitable for coke oven gas, producer gas, coke tail gas, oil shale tail gas, carbide tail gas, ferroalloy tail gas and other industrial tail gas. The utilization of these combustible coke oven gas for power generation can not only solve the air pollution caused by emissions, but also save power resources.
