填埋沼气直燃型热泵系统构建与流程研究
System construction and flow process study of a direct-fired heat pump system based landfill gas
摘要
Abstract
The main reclamation and utilization approaches of garbage landfill gas (LFG) was analyzed, the system configuration of LFG driven direct-fired heat pump and the flow process of LFG collection and purification were studied, the economic properties of the system was also calculated-Results of the study show that compared with coal-fired boiler, gas-fired boiler and electricity driven heat pump, a input power of 500 kW LFG fueled heat pump system, which is assumed to operate in heating mode for 300 days annually, will save 425 tons of standard coal, 2.71 ×l05 cubic meters of natural gas or 6.42×l05 kWh of electricity. The initial cost of such a heat pump system will be paid back in about two years. Therefore, LFG driven heat pump system is an economical, feasible and environmental technology, and is also an energy-saving mode to utilize resources effectively. The economic and environmental benefits are prominent.关键词
