Comparative study of steam injection modes for a proposed biomass-driven cogeneration cycle: Performance improvement and CO2 emission reduction

Biomass fuel energy can be utilized in cogeneration cycles through the gasification process. This reduces pollution and increases efficiency of conventional cycles, makes use renewable instead fossil fuels. In this paper, order to generate both electricity cooling, a system has been proposed using biomass Then, various ways injecting steam into each cycle are improve its performance. The following suggested modeled: CHP with injection combustion chamber, gasifier, gasifier chamber simultaneously. All initially analyzed from energy, exergy, exergoeconomic, environmental perspectives. Following analyses results compared discussed select best balance terms thermodynamics, economics pollutant emissions. parametric study is which, along determining influence changing an important thermodynamic parameter on performance, simultaneous two parameters calculated verified. show that steam-injected about 5.43% more efficient than cycle, carbon dioxide emissions 5.2% lower. Also, by offers highest reduction. Additionally, simultaneously increasing mass flow rates exergy costs increased 11.2% 3.5% respectively, CO2 emission reduced 12.5%.
