CFD analysis of double-chambered crematories using biomass producer gas as a fuel source
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 6
Abstract
This paper describes the simulation results of a biomass producer gas-based, double-chambered crematory using CFD analysis. The specific properties of biomass gas, such as thermal conductivity, specific heat capacity and viscosity, were determined by using the constituents of coffee bean pulp-derived gas obtained from the experiment. The criteria of simulation consist of coffins and human corpses contained in the primary combustion chamber, whereas the standard k-epsilon viscous model and SIMPLE algorithm were used. The simulation results show that the modified model, with a 25 degree downward angle in the primary chamber and an adjusted air nozzle, presents a good effectiveness in heat transfer and turbulent intensity. In addition, the results of the NO prediction present a high formation rate if there is only primary chamber ignition. However, the NO formation rate will increase when operating both primary and secondary chambers. Therefore, using the CFD assistant in the biomass gas-based double-chambered crematory can achieve various benefits, such as reducing apparatus construction costs and the experiment time, including the availability for pollution prediction.
