Abstract
Moist combustible matter is burned in a fluid bed reactor following a drying treatment in which the combustible matter is brought into contact with hot sand circulated from the fluid bed reactor. The water in the combustible matter is evaporated at a relatively low temperature in the drying treatment, thereby conserving heat in the system. The exhaust vapor from the drying treatment is handled separately from the reactor exhaust gases to condense the vapor therein before subjecting the remaining gas to odor-destroying high temperature.
