Abstract

The present invention relates to a heating apparatus having an object to form a construction of high thermal efficiency so that a heat transfer area of a surface to be heated in a heating chamber may be made small so as to miniaturize the whole equipment, and to utilize the whole quantity of supplied oxygen effectually thereby to suppress generation of polution materials. The heating equipment has a combustion gas inflow port (19) and an exhaust gas outlet (14a) at the bottom portion and in the vicinity of an upper opening end, respectively, and is provided with a heating chamber (14) installed with a cover body (4) on the top portion thereof, a plurality of pipe bodies (11) which are supported by a can plate provided in the cover body (4) and hung vertically in the heating chamber, a plurality of buffle plates (16) which are penetrated with these pipe bodies and disposed so as to form a labyrinth ranging in upward and downward directions in the heating chamber, a main catalytic combustion equipment (18) connected to the combustion gas inflow port (19), a plurality sheets of partition plates (17) provided in the heating chamber so as to partition the labyrinth into a plurality of chambers in upward and downward directions and a plurality of auxiliary catalytic combustion equipments (21a, 21b) provided so as to connect both chambers on the down side and the up side of each of these partition plates.
