Abstract

The invention discloses a biomass gas and natural gas coupling power generation device, which comprises a combined cycle power generation device and a biomass gasification device, wherein the combinedcycle power generation device comprises a gas compressor, a gas turbine combustion chamber, a gas turbine, a separator, a waste heat boiler, a steam turbine, a condenser and a water pump; and the biomass gasification device comprises a biomass feeding hopper, a biomass gasification furnace, a cyclone separator and a gas compressor. According to the invention, high-temperature flue gas at the outlet of the gas turbine is used as a gasifying agent for biomass gasification, heat is provided for the gasification process, and an external heat source does not need to be used for providing heat forthe biomass gasification process any more, so that the energy consumption of biomass gasification is greatly reduced, the gasified biomass gas and the natural gas are mixed and combusted for combinedcycle power generation, efficient utilization of biomass energy is achieved, and the comprehensive utilization efficiency of energy of a natural gas power plant is improved.

Description

technical field [0001] The invention belongs to the field of biomass gasification power generation, and more specifically relates to a biomass gas and natural gas coupled power generation device and method. Background technique [0002] At present, the contradiction between the continuously rising global energy demand and the shortage of fossil energy is becoming more and more acute. Biomass energy, as the fourth largest energy after coal, oil, and natural gas, is rich in reserves, CO 2 Features such as zero emissions will become an ideal choice to support the sustainable development of the global economy. [0003] Biomass includes not only original agricultural, forestry and aquatic resources such as crops, wood, and seaweed, but also industrial organic waste such as pulp waste, alcohol fermentation residue, municipal solid waste, sludge, and human and animal manure. Biomass resources are rich in reserves, widely distributed, and have the advantages of renewability, stora...
