Abstract:

PURPOSE: To improve heat producibility in a furnace and contrive the reduction of the space occupied by the furnace as well as the shortening of the furnace temperature-raising time.
CONSTITUTION: The fluidized bed heating furnace 1 is provided with a furnace body 2 having an opening part formed at its upper part, a retort 3 installed vertically in the furnace body 2, the finely divided particles 11 filled in the retort 3 to form a high temperature fluidized bed in the retort 3 and the gas burners 12A and 12B having disposed below their lower ends a combustion gas blowout tube 14 which blows out the combustion gas against the finely devided particles 11 to heat and fluidized them. This furnace is further provided with a vertical continuous carrying device 16 which carriers the material W to be heated retained by a work retaining pipe 17 in the vertical direction from an opening of the furnace body 2 and, in the course of carrying, immerses and heats the material W in the fluidized bed, a porous cast plate 9 for uniformly dispersing the fluidizing auxiliary air blown in from a hearth part to fluidize the finely divided particles 11 and an external burner 21 for heating the retort 3 from outside.
