Performance analysis of biomass boiler-organic Rankine cycle with assisted cascade heat pump for combined heat and power generation including exergy-costing

Performance analyses and economic evaluations based on exergy-costing of a biomass-boiler organic Rankine cycle coupled with a cascade heat pump system for combined heat and power generation were investigated. The net power outputs of the Rankine cycles were 7 and 20 kWe at the condensing and evaporating temperatures of 40 and 100oC, respectively. The heat…
