1.前言 自从七十年代石油危机以来,合理使用和节约燃料,已成为全世界普遍关注的问题,各国都在根据自己国内的能源结构情况,制定相应的能源政策。我国的能源结构,煤炭占70％以上。按照我国的能源政策,在今后改造或新建轧钢加热炉时,都要贯彻以煤为主的方针。目前,全国就轧钢加热炉而言,燃油加热炉约占60％以上。在今后进一步贯彻我国的能源政策的过程中,予计燃煤加热炉将会有一定数量的增 1. Introduction Since the oil crisis of the 1970s, the rational use and fuel savings have become a common concern in the world. All countries are formulating appropriate energy policies based on their domestic energy structure. China’s energy structure, coal accounts for more than 70%. According to China’s energy policy, in the future transformation or new rolling furnace, we must implement the principle of coal-based. At present, the country on the rolling furnace, the fuel heater about 60%. In the future to further implement our energy policy in the process, it is estimated that there will be a certain number of coal-fired heating furnace
