摘要
针对火力发电厂输煤系统粉尘严重超标、危害严重的问题,分析其原因主要有:冲击风量过大,形成系统正压;落煤管截面积大,形成诱导风;自动控制程度不够等.对此采取了相应新技术:导料槽密封封尘、皮带导料槽内粉尘疏导、改进导料槽内的密封挡板等.经过技术改造后,降压除尘密封效果好,节能降耗经济效益明显.
After analyzing the serious over standard problem of coal handing system,the reasons are the following：the system positive pressure caused by excessive impact wind volume,the induced wind caused by inadequate automatic control etc.New technologies such as sealing the grate discharge chute,grooming dust in belt grate discharge chute,improving the sealing baffle etc.After technology transformation,the good sealing effect of pressure reduction and dust removal is achieved and the economic benefit is significant.
