Heat exchanging system for a heat engine using compressed gaseous fuel as fuel.

摘要

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.
