Comparative Energy and Environmental Analysis of Combined Cycle CHP Combustion Operations via Simulation for Biomass and Industrial Materials Derived from Waste

The Combined Cycle Combined Heat and Power (CCCHP) systems are an effective way to improve energy efficiency and reduce emissions. This paper examines the energy and environmental impact of CCCHP combustion using waste biomass like the biomass of spent wash (SW), waste crankcase oil (WCO), and bagas...

description The Combined Cycle Combined Heat and Power (CCCHP) systems are an effective way to improve energy efficiency and reduce emissions. This paper examines the energy and environmental impact of CCCHP combustion using waste biomass like the biomass of spent wash (SW), waste crankcase oil (WCO), and bagasse (BA) using an advanced Ebsilon Professional 16 software simulation model. The simulations were designed to achieve 150 MW total power output and 25 MW heating energy. Simulation results indicate that the minimum fuel feed requirement of a 10.762 kg/s flow rate was recorded at the highest calorific value (CV) fuel briquette of 1:8 ratio BA–WCO. The BA–WCO system demonstrates a significantly higher heat recovery capacity in the heat recovery steam generator (HRSG) compared to the BA–SW system. At a 1:8 ratio, it recovers 1463 kJ/kg versus 583 kJ/kg, and 1391 kJ/kg versus 498 kJ/kg at a 1:3 ratio. The CCCHP efficiency was much higher for BA–WCO than those developed from spent wash–bagasse, yielding up to 41.1% compared to a maximum of 26.71%. Furthermore, the BA–WCO system showed a better result than the BA–SW CCCHP system by emitting a low amount of flue gas with low temperature.
