摘要：Targeting on the different gas utilization fields promulgated in the "Natural Gas Utilization Policy" by National Development and Reform Commission of China, this paper measured the emission reduction effects of replacing current fuels with equivalent calorific value of natural gas, and based on these measurements, re-ranked the priority of different gas utilization fields. The results show that: the air pollution abatement effects of natural gas heating ranks at the top level among all different utilization fields. This paper also calculated the scale of air pollutant abatement effect by replacing coal with natural gas for central heating in 15major heating cities of China in 2010, and proved that significant emission reduction effects on CO2 (21.91 million tons), particulate material (7.34 million tons), SO2 (402.1 thousand tons) and NOx (225.6 thousand tons) can be achieved by converting fuel from coal to natural gas in central heating in cities of China.展开
