Gases containing tar and other condensable components are cleaned by cooling them in a circulating fluidized bed reactor (2) provided with cooling surfaces (8). Into the fluidized bed reactor are led solids separated from the cooled gas in a cyclone separator (3) and other solids. Tar and other compounds condense on the solids in a mixing chamber (9) disposed before the cooling surface in the reactor.
