A comparative thermoeconomic evaluation of three biomass and biomass-natural gas fired combined cycles using organic Rankine cycles

Thermodynamic and thermoeconomic analyses are reported of three proposed biomass, and biomass-natural gas, combined cycles: biomass integrated co-fired combined cycle, biomass integrated post-firing combined cycle and externally fired combined cycle. Various working fluids are assessed for the bottoming organic Rankine cycle. Plants using R141b in the bottoming cycles are observed to have the highest energy and exergy efficiencies. Varying the...
