A method of combustion and a combustion plant in which absorbent is regenerated is described herein. During the combustion of a fuel in a combustion chamber enclosing a fluidized bed, a fuel and an absorbent are supplied to the fluidized bed. The combustion gases generated during the combustion are collected and purified in a separating member by separation of solid material from the combustion gases. The separated solid material is recirculated to the fluidized bed through a channel, and a gaseous medium is supplied in a controlled manner to the separated solid material present in the channel in order to displace the combustion gases and provide a chemical reaction.

Method of combustion and a combustion plant in which absorbent is regenerated

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.
