Gasification vs. Direct Combustion? Which is better ...

Mar 30, 2014· Direct combustion systems are also proven on a much larger scale. For example, the 100 MW facility in Gainesville, FL is a typical size and can be built to produce 300 MW or more. Gasification does not have much experience on that scale.

Direct biomass combustion WISIONS of Sustainability

Direct biomass combustion. Combustion is the oldest and most frequently applied process to extract the energy content from solid biomass. During combustion, most of the energy is released in form of heat. Different thermodynamic processes can be used to transform part of this heat into electric power.
