Heating method and apparatus.

摘要

Method and apparatus for heating materials such as metal rods whereby hot combustion gases are blown against the material and allowed to pass through a gas-permeable partition located inside the heating apparatus so that the partition is heated to radiate a great amount of heat into the apparatus, further increasing the temperature of atmosphere in the apparatus heated by the hot combustion gases so as to accelerate the heating of the material. After the combustion gases have thus passed through the partition, heat is further transferred from the gases to a recuperator means located inside the apparatus so that the gases are then allowed to discharge into a flue under lowered temperatures.
