灰渣塌落引发的锅炉灭火故障案例分析及对策
摘要
炉膛上部灰渣塌落造成的锅炉灭火故障较多
是影响锅炉安全运行的主要问题之一。对此
提出了消除结渣源
避免低氧运行
改善不良配风
对带有渣池的固态除渣锅炉将连续除渣改为定期除渣
延长除渣周期
降低渣池水位
提高渣池存渣量等措施。
Abstract
Many outfire troublers resulted from ash-slag collapse in the furnace are main problems affecting safe operation of boilers.For this
some measures have been put forward
including eliminating the source of slagging
avoiding operation under low oxygen concentration
improving poor air distribution
changing continuous slag removal into periodic removal
lengthening the period of slag removal
lowering the water-level in slag pool
and increasing the slag storage capacity in the slag pool etc.
