I. Introduction
Biomass gasification is a thermal conversion of solid biomass to gaseous fuel, in which the energy stored in the biomass is converted to calorific value of the produced gas. The fuel gas obtained from gasification is called Syngas, which has major components: Carbon Monoxide CO, Hydrogen H2, Carbon Dioxide CO2, and small fractions of Methane CH4. The fraction of each component gas in syngas is known to vary with the type of biomass [1], [2], initial moisture content of feedstock [1], [3], particle size [4], [5], operating temperature[1], [6], [7], and air fuel ratio (AFR) [3], [7], [8]. The fact that the composition of syngas and its resulting calorific value, vary with type of biomass, type of gasifier, and operating conditions, calls for a means of predicting the calorific value of syngas produced.
