Method for generating high-grade heat energy-high-temperature and high-pressure fuel gas through biomass combustion

The invention discloses a method for generating high-grade heat energy-high-temperature and high-pressure fuel gas through biomass combustion, and belongs to the technical field of energy and power engineering. The dried biomass is injected into the high-pressure combustion chamber in the form of dense particles by a biomass pump, which works synchronously with the high-pressure combustion chamber. The dense particles are biomass particles that reduce compression standards, have airtight compactness during formation, and are readily combusted without pursuing specific shapes when injected into a high pressure combustion chamber. The combustion heat value of the dried compact particles in the high-pressure combustion chamber is higher, and high-grade high-temperature and high-pressure fuel gas is formed. The ash beating device is good in sealing performance, ash falls through the sealed ash beating device or mechanical vibration, and ash is continuously discharged in an intermittent or sealed state.
