煤质变差对浓相气力除灰系统的影响分析
摘要
某300 MW机组由于煤质变差导致浓相气力除灰系统无法正常运行
使除灰系统出力增加
除灰系统输灰的稳定性降低
除灰系统输灰用压缩空气的裕量减小
灰库背压提高
除灰系统的磨损加剧。对此
进行了分析并提出了相应的解决措施。
Abstract
Owing to worsening coal quality
the dense phase pneumatic ash conveying system of a 300 MW unit can't be in normal operation
making the output capacity of said ash conveying system to be increased
the transporting stability of said system to be decreased
the margin of compressed air used for transportation in the said system to be reduced
the back-pressure in ash bunker to be enhanced
and the wornout of the said system to be intensified.The above-mentioned problems have been analysed
and corresponding solving measures being put forward.
