Abstract 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. Keywords Biomass material . Gasification . Combustion . Exergy loss . HRSG
1 Introduction The natural resources which include wood, coal, petroleum, and natural gas have been the main resources of energy supply for mankind despite the drawbacks of environmental pollution, climate change, and global warming associated with such fuels. The challenging task of reducing these adverse effects has been partially met by substantial work in the area of waste to energy which is done for the utilization of biomass to generate green power. The study primarily studied biomass as fuel due to the advantages associated with it such as effective way of waste utilization, lower level of emission rate, and suppressing electricity concerns. However, the direct combustion of biomass to energy conversion technology is worsened by the heterogeneous composition of waste materials that leads to

unacceptable consequences. For example, combustion of wood in traditional fire places has low efficiency and has adverse effects on the environment due to the release of particulate matter and various unburned hydrocarbons. Obviously, it is subject to increasing restrictions at least in densely populated areas. These thermodynamic and environmental disadvantages of direct combustion of biomass have been suppressed to a large extent by adopting energy conversion technology which is an efficient process to transform biomass fuels into energy carriers through gasification of biomass. The biomass
