In a hot gas generating apparatus coal is fed to a first gasifying fluidized bed wherein it is partially gasified to generate a combustible gas and char. The char is circulated to a second combustion fluidized bed for burning in the presence of excess air. The combustible gas is mixed with the oxygen rich gases from the second bed and burnt to give a hot gas product.

A heating chamber for pellets of glass batch material has a pellet inlet in one wall of the chamber and a pellet outlet at a lower part of the chamber so that a bed of pellets is formed with an upper surface inclined at an angle of repose of the pellets. Hot gas is fed into the bed of pellets through a plurality of outlets arranged in a plane parallel to the surface of the bed so that gas emerging...
