Abstract A method of treating process gases by cooling the process gas in the reactor so as to bring the process gas into con- tact with fluidized solid particles which are separated from the process gas after treating and mainly recirculated back to the reactor, in which method the process gas to be treated is mixed either simultaneously or at a short interval with both recirculated solid particles and gas, which gas, at least partly, is process gas which has been treated and from which solid particles have been separated after treatment, and in which method at least one of the components, i.e. solid particles or gas, to be mixed with the treated gas is cooler than the process gas to be treated. An apparatus for treating process gases by cooling the process gas in the presence of solid particles, which apparatus comprises a vertical reactor, at the bottom of which there is an inlet opening for the process gas, and in which apparatus a mixing chamber is fitted to the reactor, said mixing chamber having a conical bottom tapering downwards with at least one inlet opening disposed low at the conical bottom or in the immediate vicinity thereof, which opening is in- tended for a gas to be mixed with the process gas or for an evaporating liquid and in which apparatus at least one inlet pipe for solid particles is fitted to the wall or conical bottom of the mixing chamber.
