近年来,为了降低炼铁工序的综合能耗,除努力提高热风炉的送风温度外,特别注重提高热风炉本身的热效率。对热风炉进行热平衡测定,分析其热量利用状况,可以明确提高热风炉热效率的方向。 热风炉在设备结构、工作制度及测试条件等方面有其特点,其热平衡和热效率的测定及计算有一定的特殊性。本文将讨论其测定与计算的特殊问题,提出适于不同条件与
In recent years, in order to reduce the overall energy consumption of the ironmaking process, special efforts have been made to increase the thermal efficiency of the hot blast stove in addition to efforts to increase the blast temperature of the hot blast stove. The determination of heat balance furnace heat balance, analysis of the use of heat, you can clearly improve the thermal efficiency of the hot stove direction. Hot blast stove has its own characteristics in terms of equipment structure, working system and test conditions, etc. The determination and calculation of heat balance and thermal efficiency have certain particularities. This article will discuss its special problems of measurement and calculation, put forward for different conditions and
