摘要

对某电厂2×210MW机组锅炉采用LNB+SCR联合脱硝技术进行了脱硝系统改造

其中SCR工艺采用高灰型布置

反应器入、出口不增设灰斗

选择蜂窝式催化剂

按"2+1"模式布置

增设蒸汽吹灰器和声波吹灰器

以液氨作为还原剂。由于燃用的煤种含硫量较低

原空气预热器换热管管径较大

因此空气预热器不做改造;但必须对引风机进行改造

以满足新系统要求。

Abstract

Denitration transformation of two 210MW unit boilers in a power plant was presented.The low NOxburner combined with SCR technology was adopted.For the SCR device

high ash content layout was employed

and no inlet and outlet ash bucket was equipped;the honeycomb catalyst was selected and arranged according to"2plus 1"mode;the steam sootblower and acoustic sootblower were applied

and liquid ammonia was used as the reductant.Due to low sulfur content in the fired coal and large diameter of the original air preheater tubes

the air preheater can not be modified.However

the original induced draft fan can not meet needs of the new system

which must be transformed.
