提高锅炉热效率，关键是减少锅炉在运行中各种热损失，如化学不完全燃烧、机械不完全燃烧、排烟、炉体散热等热损失。为此可采取以下措施。1减少化学不完全燃烧损失。将原锅炉配各的斜直线吊装前拱改为抛物线状节能型炉拱；对原后拱进行加长处理。其目的是增加前拱部位辐射面积 Improve the boiler thermal efficiency, the key is to reduce the boiler in the operation of a variety of heat losses, such as incomplete chemical combustion, mechanical incomplete combustion, exhaust, furnace heat and other heat losses. To this end can take the following measures. 1 to reduce the chemical incomplete combustion loss. The original boiler with a straight line before the ramp tilting to a parabolic energy-saving furnace arch; the original arch for the longer processing. Its purpose is to increase the radiation area of ​​the arch area
