【摘要】 对燃气锅炉采暖3种方式的投资、运行费用、单位面积耗气量和污染物排放量进行了比较。对于燃气耗量和大气污染物排放量,单户采暖最低,分散采暖居中,区域采暖最高。对于低层住宅应优先选用单户采暖,高层住宅、公共建筑和商业建筑应优先采用模块式燃气锅炉分散采暖,大规模的燃气锅炉区域采暖不宜推广。更多还原

【Abstract】 A comparison between three heating methods with gas-fired boilers is made on the aspects of investment, operation cost, gas consumption per unit building area, and emission of atmospheric pollutants. For the gas consumption and emission of atmospheric pollutants, the household heating is the lowest, the decentralized heating is middle, and district heating is topmost. The household heating is best for low multiple-story building, the unit gas boiler heating is suit to high building, public or commercial building, and large-scale gas boiler regional heating is not suggested.更多还原
