锅炉是工业生产不可缺少的动力设备.安徽省现有锅炉4400多台,其中有一半以上是老式锅炉,耗煤量高,浪费大,如进行改造,使锅炉的热效率提高,这是节能的一条重要途径. 改造锅炉必须从实际出发,要因炉、因厂(场)、因煤、因地制宜.建议从两方面着手. 第一、对负量小的锅炉、实行小改小革.如:炉膛矮,水冷度大的锅炉,从改革炉膛容积着手,合理布置辐射受热面积.这样,不仅使燃料可以充分燃烧,还能提高锅炉出力.在锅炉尾部增加对流受热面积,或装置省煤器,降低排烟温度,利用余热给锅炉进热水,不但减少排烟损失,而且还能提高3—5％的热效率;经常通除
Boiler is an indispensable industrial production of power equipment.Anhui Province, more than 4,400 existing boilers, of which more than half are old-fashioned boiler, coal consumption is high, waste large, such as the transformation, so that the boiler thermal efficiency, which is energy-saving Important ways .To transform the boiler must proceed from reality, due to furnace, due to the factory (field), due to coal, according to local conditions.It is proposed to proceed from two aspects.First, the small amount of small boilers, the implementation of small change small leather, such as: furnace short , The boiler with large water-cooled degree, starting from the reform of the furnace volume, reasonably arranging the heated area of the radiation, so that not only the fuel can be fully burned, but also the output of the boiler can be increased, the convection heating area can be increased at the boiler tail or the economizer can be installed, Smoke temperature, the use of waste heat to the boiler into the hot water, not only reduce smoke emissions, but also improve the thermal efficiency of 3-5%; often pass
