摘要

介绍了日处理量为500 t的循环流化床垃圾焚烧炉外置式换热器(EHE)的设计特点

以及启动和运行特性。在焚烧炉起动过程中

较大的风量不利于EHE的启动;降低EHE循环灰积量

以及通过料腿反串进入分离器的流化风会降低分离器效率。随着循环灰量的增加

EHE内的料层高度增加

在DCS上反映出风室压力增加

热灰进出口温差降低。

Abstract

The design features of an external heat exchanger(EHE) for a 500 t/d municipal solid waste(MSW) incinerator of circulating fluidized bed(CFB) type has been presented.During process of starting the incinerator up

the comparatively large air flow rate is unfavourable for start-up of the EHE;decreasing accumulatin of circulating ash in EHE

as well as fluidized air reversely enters into cyclonic separater through its material leg

may decrease efficiency of said cyclonic separator.The height of material layer in EHE is increasing along with the increase of circulating ash

the pressure value in the air chamber is reflected on the DCS

the temperature difference of hot ash at inlet and outlet is also decreased.
