摘　　要：针对目前燃气热水炉只利用燃料的低热值的情况 ,根据利用水蒸气冷凝后放出的汽化潜热可进一步提高热效率的原理 ,开发了一种可充分利用燃料的高热值的冷凝式燃气热水炉 ,并分析了影响这种热水炉工作的主要因素 ,提出了合理的热水炉结构形式 ,根据热水炉的实际运行结果 ,总结了热水炉具有很高的热效率。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.
