Synergistic Integration of Waste Incineration and Tire Pyrolysis in a Multi-Generation System:Thermodynamic Optimization and Economic Trade-OffsOA
This study proposes a novel multi-generation framework combining municipal solid waste(MSW)incineration and tire pyrolysis to enhance resource utilization efficiency.The integrated configuration features parallel processing streams,an MSW incinerator operating at 31.25 t/h capacity coupled with a tire pyrolysis reactor handling 5.5 t/h feedstock,subjected to tripartite evaluation through thermodynamic and economic lenses.Key outcomes demonstrate:(1)By applying both linear and quadratic polynomial fitting to the case data and using NSGA-Ⅱ for optimization,the optimal flue gas extraction rate was determined to be 21.91 kg/s,with the quadratic polynomial fitting showing greater accuracy.(2)The system achieves an energy efficiency of 52.01%and an exergy efficiency of 64.83%,with the incineration boiler contributing the largest exergy loss(33.28 MW).(3)Financial viability was confirmed through discounted cash flow analysis,yielding a net present value of2.549×10^(7)USD and 4.15-year dynamic payback period.These results demonstrate the system''s potential for efficient waste utilization and economic viability.
