Drying of Biomass Biosolids and Coal: For Efficient

Mar 08 2019Drying of Biomass Biosolids and Coal: For Efficient Energy Supply and Environmental Benefits provides insight into advanced technologies and knowledge of the drying of biomass biosolids and coal in terms of improved efficiency economics and environmental impact It comprehensively covers all the important aspects of drying for a variety of biomass

The amount of heat that is produced varies depending on species climate and other factors but it is generally about 20 Megajoules of energy per dry kilogram of biomass In order for combustion to be efficient and clean the ingredients must be well mixed at the right temperatures for the right amount of time
