Abstract
An indirect heating furnace heats a substance in a reaction tube with a high-temperature combustion gas without contact between the substance and the combustion gas. The reaction tube is a stationary ceramic tube. A combustion device for supplying said heating high-temperature combustion gas into the furnace in comprised of at least one pair of regenerative burners.
Claims5
An indirect heating furnace system for heating a substance in a reaction tube with a high-temperature combustion gas without contact between the substance and the high-temperature combustion gas, said indirect heating furnace system comprising:
- an indirect heating furnace including a stationary ceramic tube as the reaction tube, and
- a combustion device which comprises at least one pair of regenerative burners, wherein each regenerative burner has a heat reservoir and a fuel introduction port, and combustion air is heated to form heated combustion air by introducing the combustion air into the heat reservoir, and the heated combustion air and a fuel supplied through the fuel introduction port are burnt to generate the high-temperature combustion gas, and wherein the high-temperature combustion gas is then supplied into the indirect heating furnace.
