Abstract

The invention relates to a distributed biomass and organic Rankine cycle combined power generation carbon heat poly-generation system and a distributed biomass and organic Rankine cycle combined power generation carbon heat poly-generation method, and belongs to the technical field of energy and the environment. The distributed biomass and organic Rankine cycle combined power generation carbon heat poly-generation system comprises a primary system, a secondary system and a tertiary system; in the primary system, crushed biomass and high-temperature combustible gas in a fluidized bed pyrolyzing furnace are decomposed into combustible gas, biological oil and biomass carbon, and waste heat resources in a mixture of the combustible gas and the biological oil are recovered in a waste heat boiler in an organic Rankine cycle power generation manner; the secondary system adopts the organic Rankine cycle power generation manner to recover waste heat of high temperature flue gas generated when the biological oil cooled in the waste heat boiler flows into an internal-combustion engine and medium and low temperature flue gas generated in the cycling process is exhausted after drying a biomass raw material and preheating returned water; the tertiary system generates a combustible gas material and residual flue gas heats the returned water. In the integral process, energy in the biomass is utilized to the greatest extent.
