日本石川岛通用锅炉公司和旭硝子公司共同研究,将陶瓷装配在锅炉燃烧炉的出口部,从而减少了煤尘,提高了燃烧效率。 炉筒烟管式锅炉是把燃烧炉产生的热风送到烟管,使之与烟管周围的水进行热交换,从而产生蒸汽。为了解决氮氧化物的问题,只能将燃烧温度控制在1000℃左右,这样势必会导致热风中含有大量的煤尘等未燃烧成分。但以往出口部采用的是金属,往往会被周围循环的水所冷却。因此未燃烧物质在此很难再燃烧,煤尘大多排出锅炉。
Japan’s Ishikawa Island General Boiler Company and Asahi Glass Company jointly study the ceramic assembly in the boiler combustion furnace exit, thus reducing the coal dust and improve combustion efficiency. Drum tube The tube boiler is the hot air generated by the combustion furnace sent to the pipe, so that the pipe with the water around the heat exchange, resulting in steam. In order to solve the problem of nitrogen oxides, the combustion temperature can only be controlled at about 1000 ° C, which will inevitably lead to hot air containing a large amount of unburned coal dust and other components. However, in the past, the export department used metal, which was often cooled by the circulating water. As a result, unburned material is hard to re-ignite here and most of the dust is discharged from the boiler.
