锅炉省煤器出口水温的控制

The control of outlet water temperature of coal economizer in boiler

本文论述了在不改变原有锅炉铸铁省煤器结构、确保省煤器安全和减少热损失的前提下,利用给水回流比来控制省煤器出口水温,使回流水热量得以充分利用。

This paper has discussed how to use the back-flow ratioof feedwater to control the coal economizer outlet water temperature underthe premise of low heat loss and good safty of coal economizer, which wasmade of cast iron and has its original construction, so that the heat ofback-flow water can be fully used.
