摘　　要：采用FLUENT软件对电站锅炉污泥掺烧温度场进行数值模拟分析。分别对污泥掺烧比例为0,1.3%,2.9%,4.8%的煤燃烧情况下的温度场进行了比较。结果表明:随着污泥与煤粉掺烧比例的增加,污泥与煤粉的混合物中灰分含量增加,可燃物的含量减少,水分大幅增加导致炉膛中心温度出现明显的变化。Numerical simulations of the temperature field of a sludge blended boiler were carried out using FLUENT to compare the temperature field of coal combustion at sludge blending ratios of 0%,1.3%,2.9%and 4.8%.The results show that as the sludge and pulverised coal ratio increases,the ash content of the sludge and pulverised coal mixture increases,the fuel content decreases and the moisture increases considerably,leading to significant changes in the centre of the furnace chamber temperature.
