我国城镇居民生活用煤在全国煤炭总耗量中占有一定比重,但家用炉灶热效率很低,仅有10～20％左右,大部分热量从烟囱跑掉了。充分利用这部分热量对于节约能源很有意义。建造集中式采暖及热水供应系统有时受到资金、设备、占地面积及其他条件限制,因此很多(特别是中小城市)居民住宅及小型分散独立式建筑物仍采用很不卫生的火炉采暖。为满足人民生活水平日益提高的需要,并充分利用家用炉灶的余热,我们与山西省定襄县暖风机厂协作研制成功G-5-01型民
The domestic coal consumption of urban residents in China occupies a certain proportion of the total coal consumption in China, but the thermal efficiency of household stoves is very low, only about 10 to 20%, and most of the heat is run away from the chimneys. Making full use of this part of the heat is very meaningful for energy conservation. The construction of centralized heating and hot water supply systems is sometimes limited by capital, equipment, floor space, and other conditions. Therefore, many households (especially small and medium-sized cities) and small, decentralized, independent buildings still use unsanitary stove heating. In order to meet the increasing needs of the people’s living standards and make full use of the residual heat of household stoves, we successfully developed the G-5-01 with the Dingxiang County Fan Heater Plant in Shanxi Province.
