Abstract

The system equipment configuration of a landfill gas (LFG) fueled biogas engine driven heat pump energy-saving system was studied

and the LFG collecting and purifying flow process was analyzed. By constructing an experimental plant

the performance of the system was tested. The results of experiments indicated that when the biogas engine operated at 70%—90% of its rated speed

the energy efficiency of the system would reach its maximum. That is because the waste heat recovery rate of exhaust fume was relatively higher

although the heat supplied by the system was not the maximum. Compared with other heating systems

biogas engine driven heat pump system can significantly reduce the consumption of fossil fuels and improve heating capability. Therefore

the heating system developed can lower energy consumption and utilize renewable energy sources comprehensively.
