分析了YG - 35/3.82 -M1型锅炉热效率低、飞灰可燃物含量高、烟尘排放浓度高的原因 ,提出了锅炉前墙加前拱折焰角 ,飞灰复燃装置和合理设计空气二次风的技术改造措施。改造后锅炉热效率达 83 567% ,提高了 6 90 2 %。燃烧效率达95 716% ,烟尘排放浓度由改造前的 174 3～ 2 0 81mg/Nm3降低到 317 2～ 4 0 1.7mg/Nm3,烟气黑度达到林格曼 1级以下 ,锅炉可以安全稳定经济清洁运行。
The reasons of low thermal efficiency, high fly ash combustibles content and high smoke and dust emission concentration of YG - 35 / 3.82 - M1 boiler are analyzed. Secondary wind technical transformation measures. After the transformation, the boiler thermal efficiency reached 83 567%, an increase of 6 90 2%. The combustion efficiency reached 95 716%. The concentration of smoke and dust emission was reduced from 174 3 ~ 20 81mg / Nm3 before conversion to 317 2 ~ 430 1.7mg / Nm3. The flue gas blackness reached below Ringerman level 1, and the boiler was safe and stable Economic clean operation.
