  还因为不懂(dong)搪瓷(ci)管空气预热器(qi)的(de)一些相关知识点,被(bei)别人叫做小(xiao)白(bai)吗?还不看(kan)看(kan)小(xiao)编写的(de)这个文章,让你摆(bai)脱小(xiao)白(bai)的(de)称号(hao):
  一、工作原理
  空(kong)(kong)气(qi)(qi)(qi)预(yu)(yu)(yu)热(re)(re)器(qi)在工作时(shi)会(hui)(hui)缓(huan)慢的(de)(de)(de)旋转(zhuan),烟气(qi)(qi)(qi)会(hui)(hui)进入(ru)空(kong)(kong)气(qi)(qi)(qi)预(yu)(yu)(yu)热(re)(re)器(qi)的(de)(de)(de)烟气(qi)(qi)(qi)侧后再被排出,而烟气(qi)(qi)(qi)中(zhong)(zhong)携(xie)带的(de)(de)(de)热(re)(re)量会(hui)(hui)为空(kong)(kong)气(qi)(qi)(qi)预(yu)(yu)(yu)热(re)(re)器(qi)中(zhong)(zhong)的(de)(de)(de)散热(re)(re)片(pian)(pian)所吸收,之后空(kong)(kong)气(qi)(qi)(qi)预(yu)(yu)(yu)热(re)(re)器(qi)缓(huan)慢旋转(zhuan),散热(re)(re)片(pian)(pian)运动到空(kong)(kong)气(qi)(qi)(qi)侧,再将热(re)(re)量传递(di)给进入(ru)锅(guo)炉(lu)前的(de)(de)(de)空(kong)(kong)气(qi)(qi)(qi)。空(kong)(kong)气(qi)(qi)(qi)预(yu)(yu)(yu)热(re)(re)器(qi)在锅(guo)炉(lu)中(zhong)(zhong)的(de)(de)(de)应用(yong)多为三分仓式,附带有火警报(bao)警系(xi)统(tong)、间(jian)隙调整系(xi)统(tong)和变(bian)频控制系(xi)统(tong)。空(kong)(kong)气(qi)(qi)(qi)预(yu)(yu)(yu)热(re)(re)器(qi)的(de)(de)(de)使用(yong)方便、操作简单、运行安全,并能(neng)(neng)提(ti)高锅(guo)炉(lu)系(xi)统(tong)的(de)(de)(de)热(re)(re)交(jiao)换性(xing)能(neng)(neng),因此在烟气(qi)(qi)(qi)锅(guo)炉(lu)系(xi)统(tong)中(zhong)(zhong)有很普(pu)遍的(de)(de)(de)使用(yong)。 空(kong)(kong)气(qi)(qi)(qi)预(yu)(yu)(yu)热(re)(re)器(qi)是收集和利用(yong)烟气(qi)(qi)(qi)余热(re)(re)的(de)(de)(de)设备。空(kong)(kong)气(qi)(qi)(qi)预(yu)(yu)(yu)热(re)(re)器(qi)的(de)(de)(de)应用(yong)能(neng)(neng)直接降低锅(guo)炉(lu)排烟的(de)(de)(de)温度,减少系(xi)统(tong)内的(de)(de)(de)热(re)(re)能(neng)(neng)损(sun)失。同时(shi),空(kong)(kong)气(qi)(qi)(qi)预(yu)(yu)(yu)热(re)(re)器(qi)的(de)(de)(de)散热(re)(re)片(pian)(pian)能(neng)(neng)够(gou)吸收和传导热(re)(re)能(neng)(neng),相当于(yu)增加(jia)了锅(guo)炉(lu)的(de)(de)(de)受(shou)热(re)(re)面(mian),提(ti)高锅(guo)炉(lu)的(de)(de)(de)热(re)(re)效率。
  二、作用(yong)
  空(kong)(kong)气(qi)(qi)预热器(qi)在锅炉中是有加(jia)热燃(ran)料所需空(kong)(kong)气(qi)(qi)的作用(yong),空(kong)(kong)气(qi)(qi)预热器(qi)的使用(yong)能(neng)改善高(gao)温(wen)空(kong)(kong)气(qi)(qi)的燃(ran)烧条件,减少燃(ran)料不(bu)完(wan)全燃(ran)烧而造成的热量损失(shi)。空(kong)(kong)气(qi)(qi)预热器(qi)的应用(yong)还可以提(ti)高(gao)炉内(nei)温(wen)度,提(ti)高(gao)辐(fu)射传热水平和受热效率(lv)。
  三(san)、特点
  1.可降低排烟温(wen)度,提(ti)高运行效率(lv)。
  2.强的耐磨,耐冲(chong)刷能力,更易冲(chong)洗。
  3.强的(de)耐腐蚀能力,同煤质(zhi)可延长(zhang)使用寿(shou)命延长(zhang)3倍以上(shang)。

  4.表面光滑,不易积(ji)灰,减少阻塞,增强换热效果。
