Abstract
A powdery substance in suspension state is heated with the high-temperature combustion waste gas exhausted from a glass tank furnace, and the air for combustion is heated with the thus heated powder substance. When the powdery substance employed is a raw material for preparing glass, the raw materials for preparing glass and the air for combustion to be supplied to the glass tank furnace are both heated therewith thereby contributing to effective recovery of the heat of the combustion waste gas.
