我厂是一个年产薄型机制纸6000余吨的小型制浆造纸企业,供热(汽)系统主要靠三台4吨/时快装锅炉。该炉对煤质适应性差,热效率低,出力不足,为搞好降耗节能,1988年我们受大型工业锅炉在鳞片炉排上安装翻煤器的启发,在2号KZL—4—13锅炉链带炉排上设置了翻煤器,降低了煤渣含碳量,提高了锅炉热效率。现介绍如下。一、运行机理链带锅炉本身不具备拨火作用,当煤经煤闸门刮成一定高度进入炉膛后,接受高温火焰及高温烟气的辐射热,从烘干、析出挥发份到逸出的可燃性气体在煤层间隙中着火燃烧,煤层表面随之着火燃烧,而挥发物中的煤焦油等物质使煤层表面粘结,阻碍空气的流通,同时密实的煤层亦会阻碍空气的流通,导致煤燃烧不
I plant is an annual output of thin paper machine 6,000 tons of small pulp and paper enterprises, heating (steam) system mainly depends on three 4 tons / hour quick-loading boilers. The furnace on the poor adaptability of coal, thermal efficiency, lack of output, in order to do a good job of reducing energy consumption, in 1988 we are large-scale industrial boilers installed in the flake grate on the inspiration, in the No. 2 KZL-4-13 boiler chain With the grate set on the coal, reducing the carbon content of cinders and improve the boiler thermal efficiency. Now introduced as follows. First, the operating mechanism Chain with the boiler itself does not have the poker role, when the coal scraped into a certain height through the coal gate into the furnace, the high temperature flame and high temperature flue gas to accept radiant heat, from the drying out of volatile matter to escape the combustible The gas glows and burns in the seam space. The surface of the seam fires and the coal tar in the volatiles binds the surface of the coal seam and impedes the circulation of air. At the same time, the dense coal seam will hinder the circulation of air and cause the coal to burn Do not
