摘要

针对新疆米东热电厂300MW机组循环流化床(CFB)锅炉床温高、炉内温度不均、稀相区灰浓度低等问题

从总风量、流化风、入炉煤粒度、上下二次风、床压、播煤风等方面进行了燃烧调整试验。结果表明

通过增加总风量和入炉煤粒度、调节一次风和二次风量的配比等措施

在不增加一次风的情况下

可使平均床温由调整前的940℃降至910～920℃

锅炉热效率达到92.15%

效果显著。

Abstract

Directing against the problems occurred on one CFB boiler of 300 MW unit in Midong Thermal Power Plant

such as high bed temperature

non-uniform temperature in the furnace

and low ash concentration in the dilute-phase zone etc.

a combustion adjustment test has been carried out in aspects of total air

fluidizing air

particle size of coal entering into the furnace

secondary air at upper and lower levels

bed pressure

and coal-spreading air etc..Results show that the measures taken

including increasing the particle size of coal entering into the furnace

increasing the total air

adjusting the proportioning ratio of primary and secondary air etc.

can make the average bed temperature to decrease from 940 ℃ before adjustment to 910~920 ℃

and making the thermal efficiency of boiler to reach 92.15%

boasting remarkable effectiveness.
