摘要

分析了某电厂600MW机组"W"型火焰锅炉试运行期间多次发生灭火的原因

认为其主要因煤质严重偏离设计值以及制粉系统运行异常所致。对此

提出了根据煤质条件带负荷、优化制粉系统运行、加强配煤、设置油枪闭锁和自投功能等措施。实施后

在煤质偏差较大的情况下

锅炉长时间运行未再发生灭火事故

燃烧稳定。

Abstract

The causes resulting in outfire of many times during period of trial operation for W-shaped flame boiler of 600 MW unit in one power plant have been analysed

it is believed that the main causes are as follows:the coal quality being seriously deviated from designed values

and abnormal operation of the coal pulverizing system.For these

many measures

such as taking load on the basis of coal quality condition

optimizing operation of the coal pulverizing system

offering functions of lockout and self-putting into operation to the oil gun etc.

have been put forward.After implementation

under condition of larger deviation of coal quality

outfire failure has never occurred again in long-term operation of the boiler

and combustion being stable.
