Abstract

The invention relates to a coupling system of a bio-based solid oxide fuel cell and a ground source heat pump. The system comprises a biomass gasification subsystem, a fuel cell power generation subsystem and a waste heat utilization subsystem which are connected in sequence; the biomass gasification subsystem comprises a biomass supply unit, a biomass gasification unit, a heat exchange feedback unit and a synthesis gas cleaning device which are sequentially connected in series, wherein the heat exchange feedback unit reacts on the biomass supply unit and the biomass gasification unit througha pipeline; the fuel cell power generation subsystem comprises a preheating heat exchange unit, a fuel cell and a waste heat boiler which are sequentially connected in series, wherein an outlet of thewaste heat boiler is connected with a heat flow inlet on the preheating heat exchange unit, and a cold flow outlet on the preheating heat exchange unit is connected with an inlet of the fuel cell; and the waste heat utilization subsystem comprises a heat source heat exchange unit and a ground source heat pump which are connected in sequence. The heat exchange feedback unit, the preheating unit and the heat source heat exchange unit are arranged to achieve multi-stage utilization of energy, and the energy utilization rate of the whole system is improved.

Description

technical field [0001] The invention relates to the field of energy, in particular to a coupling system of a bio-based solid oxide fuel cell and a ground source heat pump. Background technique [0002] Rural energy consumption is the main component of national energy consumption, so the transformation of rural energy structure is an important link to realize the transformation of national energy structure. As an important renewable energy source, agricultural waste is an urgent problem to be solved. [0003] However, the current use of direct combustion of biomass as the energy input of distributed energy systems has low energy efficiency and causes carbon emissions. Since most of the current distributed energy systems use gas turbines or internal combustion engines as prime movers, the power generation efficiency of internal combustion engines and gas turbines is lower than that of fuel cells. [0004] In addition, in addition to biomass, rural areas are also very rich in...
