Abstract

Abstract A heat exchanging system for a heat engine wherein compressed air alone or gas including air as the main part thereof is used as a gaseous combustion supporting medium, working mixture, or the like and compressed gaseous fuel is used as fuel, the system being characterized in that heat recovery is accomplished by a utilization of a multi-phase mixture which is obtained by adding liquid phase water to the compressed gaseous fuel or the gaseous fuel and a part of or the whole of the compressed air or the gas including air as the main part thereof or by contacting the former with the latter, or heat recovery is accomplished while the multi-phase mixture is produced within a heat exchanger with adding the former to the latter or contacting the former with the latter.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 134 words
A heat exchanging system for a heat engine wherein compressed air alone or gas including air as the main part thereof is used as a gaseous combustion supporting medium, working mixture, or the like and compressed gaseous fuel is used as fuel, the system being characterized in that heat recovery is accomplished by a utilization of a multi-phase mixture which is obtained by adding liquid phase water to the compressed gaseous fuel or the gaseous fuel and a part of or the whole of the compressed air or the gas including air as the main part thereof or by contacting the former with the latter, or heat recovery is accomplished while the multi-phase mixture is produced within a heat exchanger with adding the former to the latter or contacting the former with the latter.
Claim 2
Dependent Claim 134 words
A heat exchanging system for a heat engine wherein compressed air alone or gas including air as the main part thereof is used as a gaseous combustion supporting medium, working mixture, or the like and compressed gaseous fuel is used as fuel, the system being characterized in that heat recovery is accomplished by a utilization of a multi-phase mixture which is obtained by adding liquid phase water to the compressed gaseous fuel or the gaseous fuel and a part of or the whole of the compressed air or the gas including air as the main part thereof or by contacting the former with the latter, or heat recovery is accomplished while the multi-phase mixture is produced within a heat exchanger with adding the former to the latter or contacting the former with the latter.
Claim 3
Dependent Claim 39 words
The system of claim 1 wherein the compression is carried out by a multiplicity of gas compressors and the gas compressed in intermediate steps is cooled by liquid phase water which is to be added thereto or contacted therewith.
Claim 4
Dependent Claim 43 words
The system of Claim 1 wherein the compression of gaseous fuel is carried out by a multiplicity of gas compressors and the gas compressed in intermediate steps is cooled by the liquid phase water which is to be added thereto or contacted therewith.
Claim 5
Dependent Claim 37 words
The system of Claim 1 or 2 wherein the liquid phase water which is to be added to or contacted with said gaseous fuel or the like is used as a heat recovering medium and is preheated.
