Abstract

The invention relates to a distribution type biomass gasification poly-generation system and a distribution type biomass gasification poly-generation method, and belongs to the technical field of energy and environment. According to the method, biomass reacts with preheated air in a fluidized bed gasification furnace to generate biomass charcoal and crude fuel gas; the crude fuel gas is purified,and the purified crude fuel gas enters a fuel gas generator set to generate electricity; gas discharged from a gas turbine enters a waste heat boiler, and the residual heat of the flue gas is recovered and heats heat conduction oil; the heated heat conduction oil transfers the heat to an organic working substance; the organic working substance after endothermic vaporization drives a steam turbinegenerator set to generate electricity; after the work, the organic working substance enters a hot water heater, and heats preheated hot water; and then the organic working substance enters a condenser, and is converted into a liquid state so as to be recycled, and the medium-low temperature flue gas from the waste heat boiler is discharged by a chimney after the waste heat is recovered by an air preheater and a hot water preheater. According to the present invention, with the system and the method, biomass energy is converted into clean electric energy and high-quality biomass carbon to provide hot water for users so as to achieve the cascade utilization of biomass energy and improve the energy utilization.

Description

technical field

[0001] The invention relates to a distributed biomass gasification polygeneration system and a method for cogeneration, belonging to the technical field of energy and environment. Background technique

[0002] At present, my country is facing severe energy and environmental problems, and it is necessary to develop and utilize clean and non-polluting renewable energy with large resource reserves. At present, biomass energy is the only renewable carbon source. my country has abundant biomass energy resources and should be developed rationally. Utilizing biomass energy is one of the important ways to alleviate my country's energy crisis. The heat generated by the direct combustion of biomass can be directly supplied to users or used to produce steam, and then drive a turbogenerator to generate electricity. The advantage of this method is that the system is mature, but the efficiency is low. The main product of biomass gasification is combustible gas (the by-prod...
