ABSTRACT

A downdraft open top gasifier for refuse-derived fuel (RDF)-pellets was designed as a potential substitution fuel in a modified diesel engine. The gasifier reactor design consideration is intended to produce electricity of 100 kWe. The primary purpose of this paper is to address the gasifier dimensions based on parameters of a diesel engine specification data and an experimental, as well as the simulation results. A small stratified open top gasifier was used to evaluate the performance of RDF-pellets as gasifier feedstocks. The characteristics and gasification performance of RDF-pellets using this small stratified are included. A process model of RDF-pellets gasification was also developed to predict a syngas’s qualified to be combusted on the diesel-engine. Based on the points of view of this study revealed that the gasifier diameter and height of downdraft open top gasifier were found in the range of 0.7-1.4 meter and 1.8-3.5 meter, respectively. The thermal power of 225.20 kW in the syngas was obtained from RDF-pellet feed rate of 113.30 kg/hr. to meet 100 kWe of electricity production.The design of the gasifier reactor with this dimension is expected to be feasible to be coupled with a 100 kWe diesel engine for electricity production that is applied in the local municipal waste management.
