针对煤炭企业、化工企行业以及冶金企业生产中排放大量可燃气体,提出了利用“气煤混烧”技术对其工业锅炉进行改造,从而达到废气利用,保护环境,节能降耗,提高锅炉燃烧效率及企业经济效益的目的,并进行了定性和定量分析。1.“气煤混烧”技术的提出气煤混烧技术由上世纪中叶起源于美国,它最早应用于层燃炉排锅炉和抛煤机锅炉,由于这类锅炉燃烧性能差,燃烧效率低,负荷调节能力差,煤种适应性差,使其难以适应经济
In order to release a large amount of combustible gas in the production of coal enterprises, chemical industry and metallurgical enterprises, it is proposed to use “gas-coal mixed combustion” technology to reform its industrial boilers so as to achieve the utilization of exhaust gas, protect the environment, save energy and reduce consumption, Combustion efficiency and economic efficiency of the enterprise, and carried out qualitative and quantitative analysis. 1 “gas coal mixed burning ” technology put forward Gas-coal mixed combustion technology originated in the United States by the middle of the last century, it was first applied to stoker-fired boilers and boilers boilers, boilers due to poor combustion performance, combustion Low efficiency, poor load regulation, coal poor adaptability, making it difficult to adapt to the economy
