<p>PURPOSE:To provide improved efficiency in heat transmission and economized energy by heating an object to be heated by the radiation heat of open radiant tube burners and the radiation heat from air permeable solid materials generated when the combustion flame of said burners and the waste gas thereof flow through the air permeable solid materials. CONSTITUTION:An object 4 to be heated is placed on beams 2, 3, moves in an arrow direction, and is heated by the combustion flames and waste gas of burners 5. While the bottom surface side of the object 4 is heated by the radiation heat and combustion flames of open radiant tube burners 7, a part of the waste gas thereof is passed through air permeable solid materials 9a by the suction effect of an ejector 13 and is deprived of its heat by the materials 9a. The heat is converted to radiation heat which is then irradiated to the bottom surface of the object 4.</p> |
