摘要

对大同第二发电厂空气预热器堵灰现象进行了分析

认为原设计的蒸汽吹灰器由于安装位置不当、蒸汽在末端湿度增大、吹灰器喷嘴和行程设计不合理等原因影响了吹灰效果。对此

试用安装燃气脉冲激波吹灰器代替部分蒸汽吹灰器

投用后空气预热器空气侧和烟气侧阻力明显降低

吹灰效果良好。

Abstract

Analysis of ash clogging phenomenon on air preheater of Datong Power Plant No.2 under the State Power Corp has been carried out. It is considered that the efficiency of originally designed steam operated shoot blowers was influenced upon by several factors

such as non-suitable position of installing

increasing humidity of steam at the final end

as well as non-reasonabe design of nozzle and stroke concerning the steam operated shoot blowers etc. For these reasons

it is tried to install fuel gas impulse exciting wave operated shoot blowers for replacing some steam operated shoot blowers. After putting the new type shoot blowers into operation

the resistance on both air and gas sides of the air preheater has been obviously lowered

the effectiveness of shoot blowing being excellent.
