传统的燃油(气)锅炉在正常工作状态下的排烟温度在130。-240。之间,锅炉尾部排出的烟气中所含的水蒸气体积在15%-20%左右。这些高温水蒸气中蕴藏着大量的显热和潜热,传统锅炉在未加以利用这部分热量的情况下将这部分热量直接排往大气,造成了热能的流失。冷凝式燃油(气)锅炉的核心技术就是通过降低锅炉排烟温度,使锅炉昀烟气温度被冷凝到露点以下,烟气温度越低,冷凝水越多,可被吸收的潜热量就越大,从而达到节能的目的。
The exhaust temperatu re of traditional fuel (gas) boilersisbetween 130 0 t0 240 0 under normal working state. The
proportion of the volume of water vapor contained in theexhaust gas is from 15% t0 15% among the gas of the tailof the boiler. The high temperatu re steam contains a lotof sensible heat and Iatent heat. Traditional boiler directly
discharges into the atmosphere without fully using thispart of heat, which may cause the Ioss of heat energy.The core technology of condensing fuel (gas) boiler is tocondense the temperature of the gas of the condensingboiler below the dew point by reducing the smokeexhaust temperatu re of the boiler. The Iower the flue gastemperatu re is, the more water will be condensed, thegreater the amount of Iatent heat can be absorbed.Thus,the goal of energy saving can be achieved.
