Abstract
India is developing country. If country will be increases then demand of increase will be increase. But at the same time, we as a nation have to economize on our energy costs to focus on human developmental needs. In such context, the idea of biomass energy becomes very important and relevant. With its inherent advantages of carbon neutrality and sustainability, biomass energy is the way forward for the nation and the world at large scale. Though many forms of bio-energy are in focus of many research and development organizations, harnessing the biomass energy through combustion is the simplest method. In this project, we attempt to analyze and discuss the feasibility and sustainability of this method. But in practice, technical variables such as calorific value, ash content, presence of sulphur, greenhouse gas emissions play a significant role in the actual adoption of biomass as a major source of energy. To study these, we have chosen wastes of six different agriculture based biomass species such as banana (Musa acuminate), coconut (Cocos nucifera), areca-nut (Areca catechu), rice (Oryza sativa), Gram (Cicer arietinum) and palm (Borassus flabellifer). The samples were analyzed by proximate and ultimate analyses and further correlation was established through regression analysis. Proximate analysis showed that the coconut has the highest volatile matter content (i.e., 73 wt.%) and banana has the highest fixed carbon content (i.e., 20 wt.%) which indicated higher calorific values. The determination of calorific values validated the former results. Palm exhibited lowest ash content suggesting no ash related problems during combustion. Ultimate analysis performed on some of the selected species showed high carbon and hydrogen contents in the leaves of coconut and areca-nut. Out of some selected biomass ashes tested for their fusion temperatures, rice has the lowest initial deformation temperature (i.e. 938 0C) which is substantially above the boiling temperature, suggesting that all the selected biomass samples can be used safely for combustion in boilers up to a temperature of 800 0C. The bulk density of rice husk has been found out to be the highest (i.e. 336.257 kg/m3), suggesting facilitation of higher amount
