Abstract

The invention relates to a method suitable for carbon dioxide cycle power generation in a rural area by taking biomass as an energy source. By taking CO2 as a working medium, biomass energy is converted into a high pressure thermal state supercritical CO2 fluid which is high in energy accumulating density by means of a CO2 energy accumulating device of a biomass furnace, and the high pressure thermal state supercritical CO2 fluid is adjusted to an isobaric thermal state supercritical CO2 fluid through a stable current regulator for a turbine motor / a piston expander to do work to drive a generator to generate electricity. The method mainly comprises the following steps: (1) CO2 storage and transportation; (2) CO2 energy accumulation; (3) supercritical CO2 fluid tempering and power generation; and (4) CO2 cycle and back heat utilization. The method provided by the invention has the advantages of taking massive regenerable biomass resources in wide rural areas nearby as a low carbon energy source and being low in investment, stable to operate, low in self energy consumption, low in operating cost and the like.

Description

technical field [0001] The invention relates to the field of low-carbon and energy technologies, in particular to a CO 2 as working medium, suitable for CO2 using biomass as energy in rural areas 2 The method of cycle power generation. Background technique [0002] Climate change has become one of the issues that affect human survival and development, and a large amount of carbon dioxide emissions are considered to be the main cause of climate warming. As the largest developing country in the world, coal-based primary energy and firepower The secondary energy structure dominated by power generation, with the rapid growth of economic aggregate, the CO of primary energy and secondary energy 2 Emissions are characterized by rapid growth and large volumes. In response to climate change, the development of low-carbon energy, especially renewable energy and new energy, has become a consensus. Biomass power generation and supercritical carbon dioxide power generation have receive...
