我厂热处理车间加热炉采用连续式马弗炉对钢丝进行热处理。三座马弗炉的耗重油量每年达2千吨左右,约占全厂总能耗的40.7％,平均热效率仅为17％,大量的热能通过不同的途径浪费掉了。其中最显著的损失为排烟热损失,占全部热损失的53％左右。为了在马弗炉上节油降耗,提高企业能源作用率,我们提出了“在马弗炉排烟烟道里加装钢管预热器,利用排烟烟气预热空气,用于酸洗后的烘干和马弗炉本身空气助
I plant heat treatment plant furnace using continuous muffle furnace heat treatment of steel wire. Three muffle furnaces consume about 2 kilotons of heavy oil each year, accounting for 40.7% of the total plant energy consumption. The average thermal efficiency is only 17%. A large amount of heat is wasted through different channels. Among them, the most significant loss is the exhaust heat loss, accounting for about 53% of the total heat loss. In order to save fuel and reduce energy consumption in the muffle furnace and improve the energy efficiency of the enterprise, we put forward the concept of "installing a steel pipe preheater in the muffle smokestack, preheating the air with the exhaust fume, and after pickling Drying and muffle furnace itself air assist
