燃用山西贫煤电厂采用中速磨制粉系统的探讨

山西贫煤具有低挥发份、较强磨损、较高着火温度的特性。因此燃用山西贫煤的电厂多采用钢球磨制粉中储仓热风送粉或双进双出钢球磨制粉直吹式送粉系统。本文对燃用山西贫煤电厂采用中速磨制粉系统的可行性进行了分析,并提出采用该制粉方式应注意的问题,供业内同行设计借鉴。

Discussion on Power Plants Used Pulverizers Pulverizing System Burning Lean Coal in Shanxi

Lean coal in Shanxi has features of low volatile,strong wear characteristics of the higher ignition temperature etc.Therefore,power plants whitch burning lean coal in Shanxi usually used ball mill pulverizing system in the storage bin or double ball powder grinding powder feeding system of direct firing,This article analysize the ability of power plants used pulverizer pulverrizing system which burning lean coal in Shanxi,and propose the attention to using that system for the reference for the design industry peers.
