对嘉兴发电厂二期3、4号锅炉进行了介绍,分析了锅炉结渣、掉渣原因,并对掉渣引起炉膛负压和汽包水位大幅波动的原因作了详细分析,提出了行之有效的改善锅炉结渣情况的运行维护措施,包括加强燃料管理,提供入炉煤工业分析和灰熔点数据,加强吹灰器运行和维护管理等具体措施,削弱锅炉掉渣对炉膛负压与汽包水位的影响。
The second and third boilers of Jiaxing Power Plant are introduced. The causes of slagging and dross removal are analyzed. The causes of the negative pressure in the furnace and the drastic fluctuations of the drum water level are analyzed in detail. Effective measures to improve the operation and maintenance of boiler slagging, including strengthening fuel management, providing industrial analysis of incoming coal and ash melting point data, strengthening specific measures such as operation and maintenance of sootblower, and weakening the effects of boiler slagging on furnace vacuum and steam Impact of water level.
