Abstract
Abstract A combustion device comprises a combustion chamber (12), means (16) for generating gaseous products of combustion in the combustion chamber, and a passage for the gases which includes an exhaust (30) which has at least one heat recovery heat exchanger (18 to 26) therein, the heat exchanger having a surface coated with a catalytic material for oxidising the gaseous products of combustion to recover heat therefrom.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
81 words
A combustion device comprising a combustion chamber (12), means (16) for generating gaseous products of combustion in the combustion chamber (12), and passage means connected to the combustion chamber (12) and including an exhaust for the gaseous products of combustion, characterised in that at least one heat recovery heat exchanger (18 to 26) is disposed in the passage means and a catalytic material (32) is associated with the heat exchanger for oxidising the gaseous products of combustion to recover heat therefrom.
Claim 2
Dependent Claim
81 words
A combustion device comprising a combustion chamber (12), means (16) for generating gaseous products of combustion in the combustion chamber (12), and passage means connected to the combustion chamber (12) and including an exhaust for the gaseous products of combustion, characterised in that at least one heat recovery heat exchanger (18 to 26) is disposed in the passage means and a catalytic material (32) is associated with the heat exchanger for oxidising the gaseous products of combustion to recover heat therefrom.
Claim 3
Dependent Claim
26 words
A combustion device according to claim 1, wherein the or a said heat recovery heat exchanger includes tubes (34) having a layer of catalyst (32) thereon.
Claim 4
Dependent Claim
37 words

Claim 5
Dependent Claim
37 words
A combustion device according to claim 1, claim 2 or claim 3, which comprises a vapour generator having a said heat recovery heat exchanger in the form of an economiser (24) having a catalytic material associated therewith.
Claim 6
Dependent Claim
31 words
A combustion device according to any one of the preceding claims, which comprises a vapour generator having a said heat recovery heat exchanger in the form of an air heater (26).
Claim 7
Dependent Claim
83 words
A combustion device according to claim 1, which comprises a boiler having a vertically elongate gas pass (14) and one or more gas passages (30) leading off from the vertically elongate gas pass (14) and comprising the passage means, the one or more gas passages (30) including a superheater (18, 20, 22), an economiser (24) and an air heater (26) all having tubes (34) and comprising the at least one heat recovery heat exchanger, the tubes (34) being coated with catalvtic material (32).
