分析了四角切圆燃烧无烟煤锅炉产生烟温偏差较大的原因 ,针对无烟煤采取相应的措施解决由于烟温偏差引起的汽温偏差。文章在对近期某台 1 2 5MW中间再热超高压机组燃用无烟煤锅炉的两次改造和性能实验的基础上 ,对解决无烟煤锅炉的烟温偏差和汽温偏差提出了新的思路和解决办法 ,对无烟煤锅炉的再热器和尾部受热面布置提出建议。
The reason why the tangential combustion anthracite boiler has large deviation of flue gas temperature is analyzed. Corresponding measures are taken for anthracite to solve the deviation of steam temperature caused by the flue gas temperature deviation. Based on two rebuilds and performance experiments of anthracite-fired boilers for a 125MW intermediate reheat superhigh pressure unit recently, the article put forward new ideas and solutions for solving the smoke temperature deviation and steam temperature deviation of anthracite boilers , Proposed for the anthracite boiler reheater and tail heating surface arrangement.
