The application discloses a
solar energy coupled
biomass gasification and chemical chain
combustion SOFC combined cooling, heat and power
system in the technical field of distributed energy, which comprises a
solar energy assisted
biomass gasification subsystem, an SOFC power generation subsystem, a
supercritical carbon dioxide power cycle subsystem, a chemical chain
combustion subsystem and a
refrigeration and
heat supply subsystem; the
system collects
solar energy, and the gasification agent,
biomass and the gasification agent are reacted to generate synthetic gas for the SOFC power generation subsystem to generate power; the SOFC
anode tail gas enters the chemical chain
combustion subsystem to perform flameless oxidation and release heat, the high-grade heat released drives the
supercritical carbon dioxide power cycle subsystem to perform
cascade power generation, and the remaining low-grade
waste heat is recycled by the
refrigeration and
heat supply subsystem to realize the collaborative output of cold, heat and power. The application improves the comprehensive energy efficiency of the
system through multi-energy
complementation and energy
cascade utilization, and realizes
carbon dioxide enrichment in the chemical chain combustion subsystem.
