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.

Method of recovering heat of combustion waste gas arising from glass

A method of melting the raw materials for preparing glass, which method comprises feeding powdery or granular raw materials for preparing glass successively into flames jetting out of burners along the sloped furnace bed of a melting furnace, letting said raw materials fall onto the furnace bed at a location away from the position of the inlet for raw materials while heating them with said flames as well as the combustion gas, melting the raw materials for glass that land on the furnace bed by heating with said flames, and pouring the thus melted raw materials into a glass tank furnace from the side of the melting furnace where the burners are provided.
