Abstract A hot gas generator system which includes a combustor and a condenser, with the combustor connected to the condenser for condensing the product of combustion from the combustor. A hydrogen supply is connected to the condenser and then to the combustor whereby the hydrogen absorbs heat from the combustion product as it condenses and the hydrogen thereby is preheated prior to entering the combustor. An oxygen supply is connected to the combustor for mixing with the hydrogen during combustion. The combustor is part of an integrated heat exchanger/combustor whereby a minor portion of the hydrogen passing through the condenser is used in the combustor for burning purposes and a major portion of the hydrogen is passed through the combustor for superheating the hydrogen prior to delivering the hydrogen to a prime mover, such as a thruster or a turbogenerator of a space platform or the like.
A hot gas generator system, comprising: combustor means; condenser means; means connecting the combustor means to the condenser means for condensing the product of combustion from the combustor means; hydrogen supply means; means connecting the hydrogen supply means to the condenser means whereby the hydrogen absorbs heat from the combustion product as it condenses and the hydrogen thereby is preheated; means connecting the hydrogen preheated in the condenser means to a heat exchanger portion of the combustor means whereby the hydrogen absorbs the heat of the combustion and the hydrogen thereby is superheated; means supplying at least a portion of the superheated hydrogen to the combustor for combustion therein; oxygen supply means; and means connecting the oxygen supply means to the combustor means for mixing with the hydrogen therein during combustion.
