Parametric simulation of biomass integrated gasification combined cycle (BIGCC) power plant using three different biomass materials

The research performed in the following paper is broadly based on combined power plant powered by biomass integrated gasification. The analysis is predominantly performed for first and second law efficiencies which examine the effects of gas inlet temperature to heat recovery steam generator and steam turbine pressure; change in biomass materials (solid waste to sugarcane bagasse) and eventually exergy loss in various components of the proposed cycle were studied so as to draw a comparison between them. The exergy loss is found to be maximum in the combustion chamber of the cycle followed by gasifier, heat recovery steam generator, gas turbine, and steam turbine, respectively. The analysis further reveals that the second law efficiency is lower than the first law efficiency for various fuels (solid waste, rice husk, and sugarcane bagasse) applied in the study. This can be interpreted due to comparatively higher exergy-based contents of syngas present in the system. Further, solid waste was seen to be a better fuel than sugarcane bagasse based on the analysis involving second law.
