烟气余热回收技术在冶金行业的大型加热炉中应用较多,但用于机械和兵器行业的中小工业炉及热处理油炉在我国尚无先例。为了提高产品质量,节能降耗,改善工人作业环境,国营和平机器厂首次应用烟气余热回收技术改造热处理油炉,取得显著成效,其预热空气温度达到世界先进水平。该厂改造前的热处理油炉多年来一直采用未经预热的常温助燃空气(即冷风)作为重油雾化剂,
Waste heat recovery technology in the metallurgical industry, large-scale heating furnace used more, but for the machinery and weapons industry, small and medium-sized industrial furnace and heat treatment oil furnace in our country no precedent. In order to improve product quality, save energy and reduce consumption, and improve workers’ working environment, State-owned Peace Machinery Works first applied flue gas waste heat recovery technology to reform the heat treatment oil furnace and achieved remarkable results. The preheated air temperature reached the world advanced level. Before the transformation of the plant heat treatment oil furnace over the years has been using unheated room temperature combustion air (ie, cold) as heavy oil atomization agent,
