我厂今年新建并投产的50万吨/年北蒸馏装置,其中常压炉为800万大卡/小时的圆筒加热炉。从节能方面考虑,准备在对流室上部增设六层管板式空气预热器。从而回收烟气的热能,加热冷空气来提高燃烧效果。这样带来的问题就是抽力不足,如果加台引风机,就会增加动力消耗,反而达不到节能的目的。所以必须从加高烟囱来增加抽力。经过这样考虑,圆筒加热炉直径为6580毫米而辐射室高度为15米,对流室高度为14米,
Our factory newly built and put into operation this year 500,000 tons / year north distillation unit, of which atmospheric furnace is 8 million kcal / hour cylinder furnace. In terms of energy saving, we plan to add six-layer tube air preheater in the upper part of the convection chamber. Thus recover the heat of the flue gas, heating the cold air to improve the combustion effect. This problem is caused by lack of pumping force, if Taiwan sets induced draft fan, it will increase the power consumption, but can not achieve the purpose of energy saving. So you have to increase the chimney to increase the pumping force. After this consideration, the diameter of the cylindrical furnace is 6580 mm and the height of the radiation chamber is 15 meters and the height of the convection chamber is 14 meters.
