全国钢铁企业年耗能3500多万吨标准煤,占全国总能耗的10％以上,其中约9％消耗在二千多座轧钢加热炉窑上。这些炉窑热效率一般仅在40％左右,加热每吨料热耗比日本同类炉子要高出近一倍。可见加热炉窑节能潜力很大,因此有必要对如何进一步降低炉窑能耗进行探讨。本文将就首钢近几年在加热炉节能方面所作的一些技术工作作一简要介绍,供全国同行们参考。首钢共有轧钢加热炉48座,这些炉子年耗能35万多吨标准煤,其中90％为重油。吨材燃料消耗1980年为178.3公斤标煤,1985年降到了
National steel companies consume more than 35 million tons of standard coal annually, accounting for more than 10% of the country’s total energy consumption, of which about 9% are consumed in more than 2,000 steel-rolling kilns. The thermal efficiency of these kilns is generally only about 40%, heat per ton of material heated than similar stoves in Japan nearly doubled. Visible heating furnace energy saving potential is great, so it is necessary to discuss how to further reduce the furnace energy consumption. This article will Shougang in recent years in the furnace energy-saving aspects of some of the technical work done for a brief introduction for national counterparts for reference. Shougang total of 48 steel heating furnace, these furnaces annual energy consumption of more than 350,000 tons of standard coal, of which 90% of heavy oil. Fuel consumption per tonne was 178.3 kilograms of standard coal in 1980 and dropped to 1985
