Roos C.J. Biomass Drying and Dewatering for Clean Heat & Power

WSU Extension Energy Program, 2008. — 35 p.As prices for biomass fuels increase, it is especially important to use them efficiently. In both incineration and gasification, biomass drying increases efficiency, improves operation, and can increase steam generation by up to 60%. This guide provides general information about drying biomass fuels, one element of getting the most out of biomassfired combined heat and power projects.
Dryer types used in drying biomass fuels include rotary, conveyor, cascade, and flash dryers. When selecting a dryer and designing a system, it is important to consider many factors in addition to energy efficiency, such as environmental emissions, operation and maintenance concerns, and recovery of marketable co-products.
