Abstract
Increase in population and technology advancement leads to higher generation Municipal Solid Waste (MSW). The current method of disposing solid waste of by incineration process, which operates at high capital, Operation and maintenance cost and emission of toxic gases. This paper discusses the process design to model the MSW gasifier to minimize heating requirement when compare with conventional incineration process for a waste disposal. The modelling aims to gasify the MSW to produce heating value syngas in 10 kW downdraft gasifier. The gasifier is configured in with equivalence ratio, gasification agent, feedstock flexibility, thermo-chemical process (auto-gasification) control, low tar formation and other parameters. The designed modelled yields biomass feed rate, gas flow rate, gas heating value, energy efficiency, specific gasification rate. An impressive option on reduction of landfill disposal from above designed gasifier model is feasible.
