【Abstract】 In view of existing situation that the gas fired water heater only utilizes the low calorie of fuels, based on the principle that vaporization heat from steam condensing will promote heat efficiency, this paper develops a condensing heat gas fired water heater that can utilize the high calorie of fuels, discusses the main factors that affect the smooth operation of the water heater and puts forward a rational construction. Based on the practical operation,the paper concludes that the water heater has the advantages of high heat efficiency, convenient draining of condensed water without neutralization treatment as well as remarkable economic benefit.更多还原
