随着世界能源紧张的加剧,使过去白白放散掉的低热值高炉煤气用到高温轧钢加热炉上这一课题,提到了议事日程。把被置换出的优质燃料:油、天然气、焦炉煤气等用到更需要的地方。我国的高炉煤气多用于锅炉或低温工业炉,多余的则放散了。据84年冶金部对53个企业的调查统计:全国钢铁企业每年放散的高炉煤气达81亿米~3,相当于90多万吨标煤,
As the world’s energy crisis intensified, the issue of using low-calorific blast furnace gas, which had been blown away in the past, for hot-rolled steel heating furnaces, mentioned the agenda. To be replaced by the high-quality fuel: oil, natural gas, coke oven gas and more to use where needed. China’s blast furnace gas used in boilers or low-temperature industrial furnace, the excess is dispersed. According to the survey of 53 enterprises conducted by the Ministry of Metallurgy in 1984, the blast furnace gas released by the steel enterprises in the country amounts to 8.1 billion cubic meters a year, equivalent to more than 900,000 tons of standard coal,
