Experimental and numerical investigation of throated downdraft gasifier using mango seed hull as a biomass

Bioenergy, or energy derived from biomass, has the potential to displace fossil fuels in the near future due to its abundance, cleanliness, and carbon dioxide neutrality. From biomass thermochemical treatments, the release of syngas, which can be employed in various heat and power generation systems, makes gasification particularly alluring. When a syngas with little tar and impurity is required most of the time downdraft gasifiers are among the first gasification systems that are chosen. Because it requires a lot of time and is impractical to evaluate the performance of a gasification system using all the available biomass kinds under numerous parameters, fast and quick simulation approaches with well-developed mathematical models are required for the efficient and economical utilization of energy resources. The current study aims to investigate the performance of a throated downdraft gasification system by using a model and experiments based on the characterization of pretreated biomass feedstock. Mango seed hull (MSH) a biomass wastes that is readily available locally, was used for the analyses. The producer gas generated with MSH has a composition of 18.34 % H2, 23.87 % CO, 14.83 % CO2, and 1.27 % CH4 in a wet basis. The calorific value was determined to be 4.89 MJ/Nm3. MSH is discovered to be good biomass feedstocks for producing syngas through biomass gasification.
