Solids and gases in a stream of hot gases and solids entrained in the hot gases are separated by (a) guiding the stream in a cyclone chamber for flow about an axis to separate the solids and the gases in the stream; and (b) diverting the flow of gases through a number of slots formed by tubes constituting a conduit extending ion the axial direction; and (c) flowing a coolant through the tubes. - The flow of the stream is diverted from a circumferential direction about the axis to a flow directed inwardly towards the axis. The method in combination with a boiler having an uptake with the cyclone separator disposed adjacent the upper end of the uptake and including the steps of flowing the stream of hot gases with entrained solids upwardly from the boiler along the uptake, guiding the stream to one side of the uptake for entry into the cyclone chamber along a tangential path and guiding the solids removed from the stream downwardly to the boiler along the opposite side of the uptake. The method also includes forming the tubes to a predetermined cross-sectional shape to increase their contact surface area in heat exchange relation between the hot gases and coolant.
