摘　　要：论述 2 0 0MW机组配套 6 70t/h锅炉 ,常会遇到燃煤灰份高、调峰负荷低等严重影响锅炉稳定燃烧 ,甚至导致熄火或大量投油助燃的情况。通过选用双置浓淡分离燃烧器等一系列改进措施后 ,既能保持锅炉稳燃提高效率 。The 670t/h boiler of a 200MW power plant often has to cope with a variety of unfavorable conditions, which can seriously impair the stable combustion of the boiler, and even cause a flame failure or entail the necessity to go for a copious oil assisted combustion. Such conditions include high ash content of coal and low peak shaving load, etc. A series of measures were taken to improve the situation, which resulted in a stable combustion, higher efficiency and reduced oil consumption for the boiler, contributing to an increase in economic benefits.
