作为大量使用能源的锅炉设备,如果能很好的经济运行,则在节约能源方面将有极大的作用。因之,在锅炉最佳工况运行中,开展低过剩空气运行,是最普遍被重视而进行研究的。一、锅妒设备运行经济工况的简要解析就燃油炉来说,锅炉热平衡表达形式如下: Q_P~P=Q_1+Q_2+Q_3+Q_4+Q_5 (1)式中 Q_P~P—输入锅炉的热量;Q_1—锅炉输出有效利用的热量;Q_2—排烟热损失;Q_3—化学不完全燃烧热损失;Q_4—机械不完全燃烧热损失;Q_5—从炉墙等的辐射热损
As a boiler plant that uses a large amount of energy, it will play a significant role in energy conservation if it is economically viable. Therefore, it is the most common and important study to carry out the operation of low surplus air in the best operating condition of the boiler. First, the boiler jealous equipment operating economic conditions a brief analysis of the fuel boiler, the boiler heat balance expression is as follows: Q_P ~ P = Q_1 + Q_2 + Q_3 + Q_4 + Q_5 (1) Where Q_P ~ P- heat input boiler ; Q_1 - the amount of heat that is effectively utilized by the boiler output; Q_2 - heat loss from exhaust heat; Q_3 - heat loss from chemical incomplete combustion; Q_4 - heat loss from incomplete mechanical combustion; Q_5 - radiative heat loss from furnace walls
