Abstract
A gas heating apparatus comprises a duct constructed by a heat insulating material having a heat resisting property, a plurality of honeycombs disposed across in the duct so as to oppose to a direction of a gas flow in the duct, the honeycombs being formed of a material having a heat resisting property, and a plurality of heat radiating members disposed inside the duct so as to oppose to the honeycombs, respectively, for radiating heat to the honeycombs. The gas entering the duct flows therein and is heated during the passing through the honeycombs. The honeycombs are constituted as partition walls.
Claims7
A gas heating apparatus comprising:
- a duct means constructed by a heat insulating material having a heat resisting property;
- a honeycomb means disposed across the duct so as to be opposed to a direction of gas flow in the duct, said honeycomb means being formed of a material having a heat resisting property;
- and
- a heat radiating means disposed inside the duct so as to be opposed to said honeycomb means for radiating heat to the honeycomb means, said heat radiating means being composed of a combustion gas pipe comprising a pipe structure having an upstream side portion with respect to a fuel flow direction which is formed as a venturi, a fuel supply pipe connected to the pipe structure at an upstream side of the venturi and a catalyst portion disposed at a downstream side of the venturi.
