喷(pen)水减(jian)温(wen)器(qi)有多种(zhong)型式(shi)：多孔喷(pen)管式(shi)减(jian)温(wen)器(qi)（又称笛形(xing)管式(shi)减(jian)温(wen)器(qi)）、漩(xuan)涡式(shi)喷(pen)嘴减(jian)温(wen)器(qi)、文丘里管式(shi)减(jian)温(wen)器(qi)等。

   (1)多孔喷管(guan)式减温器。

  多孔(kong)喷(pen)(pen)(pen)管式减温器又称笛形管式喷(pen)(pen)(pen)水(shui)(shui)减温器，它由多孔(kong)喷(pen)(pen)(pen)管（笛形管）和混杂管构成。多孔(kong)喷(pen)(pen)(pen)管上开有多少喷(pen)(pen)(pen)水(shui)(shui)孔(kong)，喷(pen)(pen)(pen)孔(kong)一样平(ping)常(chang)在背向(xiang)(xiang)(xiang)汽流偏(pian)(pian)向(xiang)(xiang)(xiang)的一侧，以使喷(pen)(pen)(pen)水(shui)(shui)偏(pian)(pian)向(xiang)(xiang)(xiang)与汽流偏(pian)(pian)向(xiang)(xiang)(xiang)同等。喷(pen)(pen)(pen)孔(kong)直径通常(chang)为5-7mm，喷(pen)(pen)(pen)水(shui)(shui)速率(lv)为3～5m/s。当喷(pen)(pen)(pen)水(shui)(shui)量较(jiao)小时，设(she)置装备(bei)(bei)摆设(she)1根多孔(kong)喷(pen)(pen)(pen)管；喷(pen)(pen)(pen)水(shui)(shui)量大时，可设(she)置装备(bei)(bei)摆设(she)2根或(huo)3根多孔(kong)喷(pen)(pen)(pen)管。

  为了避免(mian)多(duo)孔(kong)(kong)喷管悬臂(bei)振动，喷管采纳高(gao)低两头牢固(gu)(gu)。多(duo)孔(kong)(kong)喷管减温器布(bu)局简(jian)略，制作装(zhuang)置便利(li)，固(gu)(gu)然雾化品质差些，但较(jiao)长(zhang)的混(hun)杂(za)(za)管足以使水点充足混(hun)杂(za)(za)、汽化和过(guo)热，故仍在大容量锅炉上利(li)用较(jiao)多(duo)。

  (2)漩涡式喷嘴减(jian)温器(qi)。

  漩(xuan)涡(wo)式(shi)喷(pen)(pen)(pen)嘴(zui)(zui)(zui)(zui)减(jian)温(wen)器由(you)漩(xuan)涡(wo)式(shi)喷(pen)(pen)(pen)嘴(zui)(zui)(zui)(zui)、文丘里(li)喷(pen)(pen)(pen)管和混杂管构(gou)成，见图(tu)7—18。喷(pen)(pen)(pen)水(shui)在喷(pen)(pen)(pen)嘴(zui)(zui)(zui)(zui)中发(fa)生激烈扭(niu)转，分开喷(pen)(pen)(pen)嘴(zui)(zui)(zui)(zui)时寄托(tuo)向(xiang)心力雾化成细(xi)小的(de)水(shui)点，构(gou)成伞状水(shui)雾，并(bing)顺着汽流偏向(xiang)活(huo)动(dong)。漩(xuan)涡(wo)式(shi)喷(pen)(pen)(pen)嘴(zui)(zui)(zui)(zui)减(jian)温(wen)器的(de)减(jian)温(wen)水(shui)雾化品质(zhi)较好，减(jian)温(wen)幅度大(da)，分外适(shi)用于(yu)减(jian)温(wen)水(shui)量变更大(da)的(de)环境，因(yin)而是一(yi)种较好的(de)布(bu)局型式(shi)。但(dan)减(jian)温(wen)水(shui)颠末喷(pen)(pen)(pen)嘴(zui)(zui)(zui)(zui)的(de)压(ya)力丧失较大(da)，对付减(jian)温(wen)水(shui)压(ya)头不(bu)富饶的(de)体系不(bu)宜利用。别的(de)，漩(xuan)涡(wo)式(shi)喷(pen)(pen)(pen)嘴(zui)(zui)(zui)(zui)也是悬(xuan)臂(bei)布(bu)局．故应在计划中采纳(na)必要的(de)步(bu)伐，避(bi)免共振的(de)发(fa)生。
