<p>A method and apparatus for treating gases and/or solid material in a circulating fluidized bed reactor, which is provided with a mixing chamber (12) for introducing gases into and mixing them with particulate solid material, an uptake shaft (14) for leading the gas suspension from the mixing chamber into a particle separator (16) and a duct (18) for returning the separated solid material into the mixing chamber. The uptake shaft is provided with heat transfer surfaces (52, 54) for cooling the gas suspension. The reaction time of the solid material is extended in the reactor by arranging the uptake shaft with at least one enlargement section (36, 38) where the flow rate of the gas suspension decreases.</p> |
