Abstract
An assembly of coaxial rotor units which form part of a grate in an industrial furnace and serve to transport as well as to admit air to solid fuel in uncombusted and/or at least partially combusted state. Each rotor unit has a shell which is assembled of heat-resistant fuel-contacting rings and has gaps for discharge of air into fuel, a hollow core which is received in and rotates with the shell and whose cylindrical wall has apertures for admission of air into compartments disposed between the shell and the core and communicating with the gaps between the rings. The end walls of the core rotate with or relative to trunnions at least one of which admits air into the core so that such air flows through the apertures of the cylindrical wall, into the compartments and issues via gaps to contact the fuel. The core can receive a cylindrical drum which has a peripheral helix or discrete distancing projections and serves to regulate the flow of air along the inner surface of the cylindrical wall so that the cooling of core is more pronounced in regions which are nearer to fuel. The rings of the shell are assembled of heat-resistant segments which are fastened to the cylindrical wall of the core.
