层燃炉尤其是正转链条锅炉,本身不具备拨火作用,在火床范围内,空气与燃料不能很好地混合,造成炉渣可燃物含量高,锅炉效率低。为了改变这种燃烧状况,我们在一台SHL20～25/400—A型锅炉上,设计安装了两道翻煤器(见图1)。这种装置使锅炉本身具备了自动拨火作用,促使空气与燃料充分地混合、燃烧,降低了炉渣含碳量,提高了锅炉热效率,节约了煤炭。 The layer burner, especially the forward chain boiler, does not have the poker effect itself. In the fire bed, the air and the fuel can not be mixed well, resulting in high content of combustibles and low boiler efficiency. In order to change this burning condition, we design and install two spoilers on a SHL20 ~ 25/400-A boiler (see Figure 1). This device makes the boiler itself has automatic dial fire, prompting the air and fuel to fully mix and burn, reducing the carbon content of the slag, increasing the boiler thermal efficiency, saving coal.
