空气源热泵用于天然气加热的经济环保性

Economy and Environmental Protection of Air-source Heat Pump for Natural Gas Heating

介绍天然气门站调压前天然气升温方案:方案1:防爆电加热器。方案2:燃气锅炉+换热器。方案3:空气源热泵型加热器。以某天然气门站作为研究对象,计算分析3种方案的经济性、环保性,方案3的年运行费用、年二氧化碳排放量均最低。

The heating schemes of natural gas before pressure regulation of natural gas gate station are introduced.Scheme 1:explosion-proof electric heater.Scheme 2:gas-fired boiler+heat exchanger.Scheme 3:air-source heat pump heater.Taking a natural gas gate station as the research object,the economy and environmental protection of the three schemes are calculated and analyzed.The annual operation cost and annual carbon dioxide emissions of scheme 3 are the lowest.
