2009年5月1日起施行的新的《特种设备安全监察条例》增加了对特种设备节能减排的要求,这就需要特种设备用户把节能减排工作作为一项重要的工作任务来抓。我国能源结构的最大特点是以煤为主,占到3/4以上[1],其中锅炉煤耗达80%左右,而锅炉的热损失包括:排烟热损失、机械不完全燃烧热损失,化学不完全燃烧热损失,灰渣物理热损失,飞灰热损失及炉体散热损失。排烟热损失是现代锅炉各项热损失中最主要的一项,约占5%~12%[2]。排烟热损失q_2是因锅炉排出的烟气
The new “Special Equipment Safety Supervision Regulations” that came into force on May 1, 2009 added requirements for energy-saving and emission reduction of special equipment. This requires special equipment users to make energy conservation and emission reduction an important task. The most prominent feature of China’s energy structure is coal, accounting for more than three-quarters [1], of which about 80% of boiler coal consumption, while the boiler heat losses include: exhaust heat loss, mechanical incomplete combustion heat loss, chemical Incomplete combustion heat loss, ash physical heat loss, fly ash heat loss and furnace heat loss. Exhaust heat loss is the most important heat loss of modern boilers, accounting for 5% to 12% [2]. Exhaust heat loss q_2 is the flue gas discharged from the boiler
