Abstract : The municipal solid waste gasification technology has been investigated using a pilot scale fluidized bed gasifier for the recovery of energy. This work focuses on the production of synthesis gas from municipal solid waste (agriculture waste, orange fruit waste and egg cover), the production of energy from municipal solid waste by combustion in fluidized bed gasifier and air discharge are used for power generation. As feedstock preparation plays an important role to increase performance of gasification, steps of feedstock preparation (sorting, shredding and dying) are explained in detailed. Syngas production and clean-up and burning process is explained. The composition of syngas produced at different stages of the experiment is also presented. The purpose of this study was to estimate the potential of gasification process an alternative to the combustion of municipal solid waste. Fluidized bed gasifier uses a relatively small amount of oxygen or water vapor to regenerate the organic compound into a combustible gas. This study found that about 65 % of the original energy of solid waste is converted to syngas and 23 % is converted to char with remaining 12 % as residue loss. The primary energy conversion is done by burning syngas in a 0.5 MW gas engine through an otto cycle power generation. The ratio of steam to biomass effects the composition of product gas. Silica sand and municipal wastes are used as bed material in fluidized bed gasifies.
