W火焰锅炉低负荷条件下掺烧煤泥的数值模拟
Numerical Simulation on Burning Blended Coal Slime Under the Condition of Low Load in W-flame Boiler
摘要
Abstract
With rapid development of coal processing industry,output of coal slime has increased obviously.It is one of effec-tive ways to realize resourceful treatment by means of mixing the coal slime in the coal-fired boiler.Therefore,on the basis of combination of field test and numerical simulation,this paper studies combustion characteristic of the anthracite blending coal slime of one W-flame boiler under the condition of low load and analyzes furnace combustion characteristic and emission characteristic after co-firing coal slimes with different ratios of 0%,5%,10%,15%,20% and 25%.The results show as the blending combustion ratio is less than 20%,temperature level in the furnace decreases,carbon content in the fly ash in-creases and NOxemission reduces.While when the ratio is more than 20%,advanced combustion of the coal slime with high volatile will produce great negative influence on later combustion of the anthracite,which may delay combustion and burn-out of the anthracite and cause inadequate combustion of mixed coals and increase of NOx emission.关键词
