是何因素致使锅炉排烟温度越来越高

2020-06-04 10:06来源:青海锅炉作者:青海锅炉网址:http://xgfqsm.com/

因为排烟热损失是锅炉各项热损失中较大的一项,一般为送入炉膛热量的百分之6左右,排烟温度每增加12~15℃,排烟热损失增加百分之0.5。所以排烟温度是锅炉运行重要的指标之一,一定要点监视。下列几个因素有可能使青海锅炉的排烟温度升高:

(8)制粉系统运行方式。对闭式的有储粉仓的制粉系统来讲,当制粉系统运行时,由于燃料中的一部分水分进入炉膛,炉膛温度降低和烟气量增加,制粉系统运行时漏入的冷空气作为一次风进入炉膛,流经空气预热器的空气量减少,使排烟温度升高,反之,当制粉系统停运时排烟温度降低。青海锅炉是一家专业生产、销售锅炉的厂家,望社会各界人士有需要者可与我们进行联系采购。
