Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
51 words
A system for delivery of a catalytic material to a combustion chamber (10,41) having a high temperature flame zone (20,44) therein characterised in that the system comprises a) admixing said catalytic material with a fluid medium; b) introducing substantially all of said catalytic material as admixed into the flame zone (20,44).
Claim 2
Independent Claim
51 words
A system for delivery of a catalytic material to a combustion chamber (10,41) having a high temperature flame zone (20,44) therein characterised in that the system comprises a) admixing said catalytic material with a fluid medium; b) introducing substantially all of said catalytic material as admixed into the flame zone (20,44).
Claim 3
Dependent Claim
37 words
A system as claimed in claim 1 in which the catalytic material is mixed with steam which steam and catalytic material are caused to atomize the fuel just prior to its entry into the flame zone (20,44).
Claim 4
Dependent Claim
37 words
A system as claimed in claim 1 in which the catalytic material is mixed with air which air and catalytic material are caused to atomize the fuel just prior to its entry into the flame zone (20,44).
Claim 5
Dependent Claim
31 words
A system as claimed in claim 3 in which the catalytic material is mixed with a stream of air prior to the air and catalytic material entering the flame zone (20,44).
Claim 6
Dependent Claim
18 words
A system as claimed in claim 4, in which the stream of air is normal chamber intake air.
Claim 7
Dependent Claim
24 words
A system as claimed in claim 4, in which the stream of air is a stream of air apart from the normal intake air.
Claim 8
Dependent Claim
22 words
A system as claimed in claim 1 in which the catalytic material is pumped as a liquid into the flame zone (20,44).
Claim 9
Dependent Claim
31 words
A system as claimed in claim 1 in which the catalytic material is mixed with the fuel prior to the mixture of fuel and catalytic material entering the flame zone (20,44).
Claim 10
Independent Claim
21 words
A system as claimed in any preceding claim, in which the catalytic material includes a platinum group metal or compund thereof.
Claim 11
Dependent Claim
91 words
In a system for delivery of a catalyst material to a combustion chamber (10;41) having a high temperature flame zone (20,44) which zone varies in size and volume as the amounts of combustible materials fed to the chamber are varied, said system being characterised in that the system comprises 1) determining the size and volume of the zone (20,44) in the chamber (10,41); 2) introducing catalyst material into the chamber (10,41); 3) controlling such introduction so that substantially all of the catalyst material is fed directly into the said zone (20,44).
Claim 12
Dependent Claim
91 words
In a system for delivery of a catalyst material to a combustion chamber (10;41) having a high temperature flame zone (20,44) which zone varies in size and volume as the amounts of combustible materials fed to the chamber are varied, said system being characterised in that the system comprises 1) determining the size and volume of the zone (20,44) in the chamber (10,41); 2) introducing catalyst material into the chamber (10,41); 3) controlling such introduction so that substantially all of the catalyst material is fed directly into the said zone (20,44).
