冷凝式燃气壁挂炉的特点及应用现状

Characteristics and Application Status of Wall-Hung Gas Condensing Boiler

冷凝式燃气壁挂炉因其特殊的内部结构,使其较普通型燃气壁挂炉可提高热效率10%以上,并节省10%的燃料费用,减少10%的氮氧化物和碳氧化物的排放,同时达到节能和环保的目的.通过分析冷凝炉的供热和燃烧特点、低温地板辐射采暖系统的特点,说明冷凝炉和地板采暖的结合是较为节能的一种采暖方式.将太阳能作为地板采暖的热源,形成"太阳能集热系统+地板采暖+辅助热源"的形式,是目前可以实现的最佳太阳能采暖方式之一.

Compared with the normal wall-hung gas boiler, the wall-hung gas condensing boiler can increase the thermal efficiency more than 10%, save fuel costs by 10% and reduce 10% of nitrogen oxides and carbon oxides emissions for its special internal structure, as well as achieve energy-saving and environmental protection purposes. Through the analysis of heating and combustion characteristics of the wall-hung gas condensing boiler and features of the low temperature radiant floor heating system, it is obtained that the combination of wall-hung gas condensing boiler and floor heating system is the more energy-efficient option. If solar energy using as a heat source for floor heating, the formation of solar collector system ＋ floor heating ＋ auxiliary heat source can be one of the best way currently achievable of solar heating system.
