The Combined Cycle System of Solar Energy and Biomass Energy Complementary Based on Organic Rankine Cycle

Abstract

Human life is inseparable from energy, but with the progress of economic development and social civilization, energy issues have attracted global attention. In order to produce clean and efficient sustainable energy, this paper designs an internal recuperative organic Rankine cycle(ORC) system, and then based on the operating principle of the ORC system, the heat collection properties of solar energy(SE) and the properties of biomass biogas fermentation are matched, and a CCS is constructed. The power generation system is a power device, which is cooled by power and supplied to the circulation system to generate electricity and refrigeration. In this paper, the performance evaluation experiment of the combined cycle system(CCS) is carried out, and the factors affecting the performance of the CCS are analyzed. The results show that the energy saving(ES) efficiency and emission reduction(ER) rate of the SE CCS are high, which not only saves energy but also protects the environment. If the ambient temperature is too high or too low, the CCS will be affected. If the temperature is too low, the system capacity and efficiency will be reduced. If the temperature is too high, the work of the micro gas turbine(MGT) will be affected. When the ambient temperature remains unchanged, increasing the methane content in the biogas can improve the power generation efficiency(PGE) of the micro-combustion engine.
