摘要
针对330 MW四角切圆燃烧Π型煤粉炉内SNCR脱硝喷枪点位的选取原则、主要影响因素、计算方法,结合锅炉受热面结构并考虑还原剂混合均匀性,最终确定喷枪的位置、数量及安装角度。
According to the selection principle, main influen cing factors and calculation method of SNCR denitrification lance point in 330 MW tangentially fired pulverized coal furnace, combined with the structure of boiler heating surface and considering the homogeneity of reductant mixing, the position, quantity and installation angle of the lance are finally determined.
