Abstract
An experimental investigation of a fixed-bed downdraft gasifier was carried out using wood pellets (Lauan wood, size：15mm×15mm×15mm), The downdraft gasifier is a cylindrical vessel having a diameter of 200mm and a height of 1000mm.
The effect of air flow rate, moisture content and air preheating temperature on the gas composition, calorific value and the gas production rate is presented.The optimum operation of the gasifier is found to be between 2.58 (Kg/Kg) and 2.37 (Kg/Kg) of air fuel ratios at the values of 6.02 and 8.18 (Kg/h) of wet feed rate which produces the producer gas with a good HHV of about 5.2 (MJ/Nm3) at a volumetric flow of 19.87 (Nm3/h) product gas.
