燃料炉从炉尾排出的烟气温度高达600～1100℃,其热损失通常为30～50%。对此大量的高温余热资源如何经济有效地加以利用,已是工业炉节能的主要方向,也是企业提高能源利用率,解决企业能源供需矛盾,降低生产成本,提高经济效益的有效途径。几年来我们对这一问题已有了共识,在利用烟气余热方面做了大量的工作,想了不少办法,比如设计了各种类型的空气予热器,把烟气用来予热助燃空气、还有用烟气余热直接予热工
Flue gas from the furnace tail flue gas temperature as high as 600 ~ 1100 ℃, the heat loss is usually 30 to 50%. How to utilize a large amount of high temperature waste heat resources economically and effectively has become the main direction of energy saving for industrial furnaces and an effective way for enterprises to improve their energy utilization rate, solve the contradiction between supply and demand of enterprises, reduce production costs and increase economic benefits. Over the past few years, we have reached consensus on this issue. We have done a great deal of work on the use of waste heat from flue gas and have come up with many ideas. For example, we have designed various types of air preheaters that use the flue gas to heat and fuel Air, as well as heat directly to the flue gas waste heat
