循環流化床窯爐(lu)鍋爐(lu)環保噴槍的研究比(bi)較：

首先，根據噴(pen)(pen)(pen)槍(qiang)結(jie)構及工(gong)作原理。一(yi)種為傳(chuan)統的(de)壓縮空氣氣力霧化噴(pen)(pen)(pen)槍(qiang)，一(yi)種為循環流(liu)化床鍋爐脫硝設計的(de)機(ji)械霧化噴(pen)(pen)(pen)槍(qiang)。

霧(wu)化(hua)噴(pen)槍(qiang)(qiang)，噴(pen)槍(qiang)(qiang)結構(gou)主要(yao)由如下及(ji)部(bu)分組(zu)(zu)成：還原劑通道、霧(wu)化(hua)風通道、機(ji)械(xie)霧(wu)化(hua)噴(pen)嘴、快(kuai)速接頭等組(zu)(zu)成。噴(pen)槍(qiang)(qiang)各部(bu)件均采用不(bu)銹鋼(gang)材料制造，機(ji)械(xie)霧(wu)化(hua)噴(pen)嘴多采用進(jin)口316L，310S不(bu)銹鋼(gang)制作。

霧(wu)化(hua)噴槍(qiang)(qiang)(qiang)安裝(zhuang)(zhuang)時(shi)(shi)(shi)裝(zhuang)(zhuang)在爐(lu)墻上預(yu)(yu)埋(mai)的套(tao)管內，套(tao)管與(yu)(yu)(yu)爐(lu)墻平齊，噴槍(qiang)(qiang)(qiang)通過法蘭固(gu)定在套(tao)管上，安裝(zhuang)(zhuang)時(shi)(shi)(shi)噴槍(qiang)(qiang)(qiang)外(wai)管與(yu)(yu)(yu)預(yu)(yu)埋(mai)套(tao)管平齊，噴槍(qiang)(qiang)(qiang)噴嘴裝(zhuang)(zhuang)配時(shi)(shi)(shi)與(yu)(yu)(yu)噴槍(qiang)(qiang)(qiang)外(wai)管向爐(lu)外(wai)縮數毫米(mi)。噴槍(qiang)(qiang)(qiang)尾部(bu)兩接(jie)(jie)口通過快速接(jie)(jie)頭分別接(jie)(jie)還原(yuan)劑和霧(wu)化(hua)風(feng)。鍋(guo)爐(lu)和脫(tuo)硝系(xi)統運行時(shi)(shi)(shi)，還原(yuan)劑由還原(yuan)劑通道進入霧(wu)化(hua)噴嘴，經機械力霧(wu)化(hua)成(cheng)合適(shi)細度霧(wu)滴噴射進入反應區，鍋(guo)爐(lu)運行時(shi)(shi)(shi)霧(wu)化(hua)風(feng)常開。
