摘      要：Energy systems with multi-energy product outputs driven by renewable energy sources are becoming increasingly *** satisfy the diversification of energy use forms in China,this study proposes a new thermochemical energy system driven by solar energy and biomass for natural gas and power *** this system,syngas from solar-driven biomass gasification is used to synthesize natural gas,whereas the unreacted syngas is burned directly in a combined cycle for power *** adjust the production capacity of the system,a shift reaction was used to change the H_(2)/CO ratio in the *** biomass gasification model was experimentally verified,and the thermodynamic performance of the system was studied *** results showed that the production rate of natural gas,with a heat value of 714.88 k J/mol,was approximately 0.306 m^(3)-SNG/kg-bio,and the primary energy efficiency was 47%.The new system showed a good energy-saving potential of 15.29%.Parametric analysis indicated that an increase in the gasification temperature led to a reduction in the natural gas production and an increase in the power output of the system,with a maximum energy efficiency of 66.72%at gasification temperature of 1050°*** an increase in the syngas share entering the transfer reactor,the natural gas production rate and energy efficiency of the system were improved with an optimum share of approximately 0.55,thereby facilitating the development and optimization of operation *** study provides a promising way to increase the share of renewable energy instead of fossil fuels.
