Abstract

This research presents the identification of producer gas resulting from the conversion of a given type of biomass in a downdraft gasifier, the use of a neural network (NN) to predict the identity for a given biomass type and  the comparison of the NN prediction to measured results of biomass fuel conversions.  Each type of biomass has different characteristics which affect the composition of the producer gas and thus its effective energy content.  This research predicts the composition of the producer gas from the characteristics of the biomass by creating a mathematical model using a neural network.  The model is then used to run simulations which are compared to actual measured values from experiments and then the accuracy of the simulations are verified with Simulink/MATLAB.  The results show that the simulation predicts the CO content of producer gas with an average error of 1.73%, 7.01% for H2, and 1.58% for CH4.  The simulation predicts the higher heating value with an average error of 0.73% and a lower heating value with an average error of 0.81%.
