摘要

为综合利用神华煤液化渣

通过自备电厂1台440t/h循环流化床(CFB)锅炉进行了掺烧15%液化渣试验

对掺烧液化渣后锅炉运行工况、污染物排放的变化情况等进行测定。结果表明

掺烧15%液化渣后锅炉整体运行稳定

但二氧化硫、总烃、挥发性卤代烃等污染物排放量增大。通过风量、床温等燃烧优化调整后

各项污染物排放得到了有效控制。

Abstract

To comprehensively use the liquefaction residue from Shenhua coal

experiments of mixed combustion with 15%liquefaction ash in a 440t/h circulate fluidized bed(CFB)boiler were carried out.The operation states in the boiler during mixed combustion and the pollutant emission state were investigated.The results show that

after the 15% liquefaction ash was co-fired

the boiler ran stably

the emission of SO2

total hydrocarbon and the volatile halocarbons increased.Especially

after the air flow and bed temperature were regulated and the pollutants emission was controlled effectively.
