在热风炉进行技术改造之后,我们深深地体会到影响风温进一步提高的主要因素就是炉尘(煤气灰)。由于实行加大风量,提高冶炼强度的措施后,炉尘的吹出量也随之大大增加。炉尘进入热风炉及烟道内,一方面粘附于加热管上,使加热管的热交换情况变坏,同时大量的炉尘堆集于加热室内,埋住了加热管的下部,缩小了管子的受热面积;另外,大量的灰堆积于烟道口和烟道内,使烟囱抽力
After the technological transformation of the hot blast stove, we deeply understand that the main factor that affects the further improvement of the air temperature is the dust (coal ash). Due to the implementation of measures to increase the air volume and increase the smelting strength, the blow-out amount of dust will also increase greatly. Furnace dust into the hot blast stove and flue, on the one hand, the adhesion to the heating pipe, so that heat pipe heat exchanger deterioration, while a large number of dust accumulation in the heating chamber, buried the lower part of the heating pipe, reducing the tube Heated area; In addition, a large number of ash accumulation in the flue and flue, the chimney pumping force
