COMPUTATIONAL ANALYSIS OF AN ADVANCED BIOMASS DOWNDRAFT GASIFIER

摘要

The aim of the present work is to predict thernperformance of the advanced biomass gasifier throughrncomputer simulation with computational fluidrndynamics (CFD) software and to predict the flow field,rnvelocity and temperatures at any spatial location. Therncomputation is then extended to study the variation inrngas composition and calorific value of the producerrngas while increase the temperature. Howeverrnvalidation of predicted results is essential to getrnconfidence in the prediction procedure. Hence arnquantitative comparison of the predicted results hasrnbeen done with the experimental results taken from thernCentre for Energy Technology, Osmania University,rnHyderabad and was found to agree well with datarnavailable in CET.
