Co-gasification of oil palm biomass in a pilot scale downdraft gasifier

Experimental Studies on Gasification of Pine Wood Shavings in a Downdraft Biomass Gasifier

Biomass is the oldest form of energy used by human beings, mainly in the form of wood. It is a renewable source of energy and has many advantages from an ecological point of view. The direct combustion of biomass generates concern among environmentalists, as it is incomplete and inconsistent and may produce organic particulate matter, carbon monoxide and other organic gases. Biomass gasificatio...

Modeling and Simulation of Downdraft Biomass Gasifier

Kinetics-free equilibrium models can predict the exit gas composition, given the solid composition and the equilibrium temperature, but they cannot be used for reactor design Hence, there is a need to develop a combined transport and kinetic model which takes into account of the kinetics of homogeneous and heterogeneous chemical reactions, transport of volatiles produced, heat and mass transfer...

Experimental Studies on Downdraft Biomass Gasifier

A process of conversion of solid carbonaceous fuel into combustible gas by partial combustion is known as gasification. The resulting gas, known as producer gas, is more versatile in its use than the original solid biomass. In the present study, a downdraft biomass gasifier is used to carry out the gasification experiments with the waste generated while making furniture in the carpentry section...

Pilot-scale gasification of woody biomass

The gasification of pine and mixed-hardwood chips has been carried out in a pilot-scale system at a range of gas flow rates. Consuming w17e30 kgh 1 of feedstock, the producer gas was composed of w200 dm m 3 carbon monoxide, 12 dm m 3 carbon dioxide, 30 dm m 3 methane and 190 dm m 3 hydrogen, with an energy content of w6 MJ m 3 for both feedstocks. It was found that the efficiency of the system ...
