我国的能源政策“以煤为主”,如何合理有效地利用煤炭燃料乃当务之急。目前技术先进发达的国家高发热值煤气的气化技术,经济上还不能够推广应用;而煤的液化,煤、油混烧技术正在研究之中;煤水浆的应用还刚起步。因此当前煤粉的悬浮燃烧和其他机械燃煤一样仍是有效的“以煤代油”燃烧方法之一。我厂1975年就在线材加热炉首先采用风扇式磨煤机,1979年型钢,开坯加热炉大修改造都采用风扇磨煤机,当时使用双管直筒煤粉烧咀,能耗一直排徊在三等炉水平。 1981年夏,马鞍山钢院(现华东冶金学院)和常熟喷咀厂合作进行“粉煤燃烧”的课
China’s energy policy “mainly coal”, how to use coal fuel reasonably and effectively is a top priority. At present, the gasification technology of high calorific value gas in countries with advanced technology and advanced technology can not be popularized economically. The technologies of coal liquefaction, coal and oil mixing are under study. The application of coal water slurry has just started. Therefore, the current suspension of pulverized coal combustion and other mechanical coal is still as effective as “coal instead of oil,” one of the combustion methods. I plant in 1975 on the wire furnace first fan-type coal mill, 1979 steel, overheating furnace overhaul fans are used fan mill, then the use of double-tube straight coal burning Tsui, energy consumption has been row around Third-class furnace level. The summer of 1981, Ma On Shan Steel Institute (now East China Institute of Metallurgy) and Changshu nozzle Tsui plant cooperation “pulverized coal combustion” class
