Direct Combustion - an overview | ScienceDirect Topics

The combustion process is largely affected by moisture content of the fuel. A biomass with high moisture content is not suitable for direct combustion. In order to sustain the combustion in a boiler, biomass is often burnt at a moisture level below 55 – 65 wt% ().
