摘要
分析了某台75t/h煤粉锅炉热效率低、结焦严重、出力不足的原因,更换了燃烧器并重新布置。测试和评价了改造前后锅炉运行状况、改造后的燃烧区域冷态空气动力场。
The reasons of low thermal efficiency, grave coking and insufficient output of a certain 75t/h pulverized coal-fired boiler are analyzed. The burners are replaced and rearranged. The running conditions before and after reforming, and the cold aerodynamic field in combustion zone after reforming are tested and evaluated.
