In biofuel drying in industrial power plants, a new multistage drying system (MSDS) can now be applied before combustion. By reducing the drying air mass flow, MSDS makes it possible to use a proportion of the combustion air in drying, and to lead that moist drying air into the combustion stages of the power plant boiler. MSDS increases the power-to-heat ratio and capacity of the power plant compared to power plants without drying systems. Previous increases came from biofuel homogenization and increased energy efficiency. Biofuel homogenization also reduces unburned organic emissions as a result of more complete combustion. © 2002 Elsevier Science Ltd. All rights reserved.
