Abstract
A method of combustion in a pressurized, fluidized bed and in the freeboard thereof. The combustion method is further characterized by the recirculation of solid sulfur absorbing materials. A gas channel, designed so as to prevent fluidizing gas from entering the channel from below, is provided such that it opens to the freeboard and to a separating member which separates particulate matter from the combustion gasses.
