In order to achieve clean and harmless treatment of medical solid waste while enhancing its resource utilization efficiency
a novel power generation system that coupled plasma gasification of medical solid waste with small modular reactor power plant was proposed. The synthesis gas generated by the plasma gasification of medical solid waste was used to drive the gas turbine to generate electricity. Meanwhile
the high-temperature synthesis gas and the heat of gas turbine exhaust were used to heat steam
feedwater and industrial water of the small modular nuclear reactor power plant. And
a comprehensive assessment of the new system from perspectives of thermodynamics and economics was conducted. Results show that medical solid waste generates 11.06 MW of electricity and provides an additional 1.16 MW of heat for heating of industrial water in the new system. Waste-to-power efficiency and energy efficiency of medical solid waste are 60.63% and 69.02%
respectively. Exergy efficiency of medical solid waste is 63.52%. Furthermore
the new design has a short dynamic investment payback period (3.3 a)
and the net present value of the project over 20 a life cycle is 900.528 9 million yuan.
