Design and Development of Downdraft Gasifier for Rural Area

Biomass is the main source of energy for a large number of small, rural, and cottage industries along with the majority of rural households. The biomass-consuming industries can be divided into two categories, namely traditional industries and new or potential industries. Traditional biomass-based industries are essentially rural cottage and small scale industries. These industries depend predominantly on biomass fuels such as wood, agricultural residues, and animal dung because biomass is cheap and its supply is assured. Biomass energy is used in these industries for direct heating (firing of bricks, lime), indirect firing (drying, baking), boiling, steam raising and distillation. The production of generator gas (producer gas) called gasification, is partial combustion of solid fuel (biomass) and takes place at temperatures of abou
