Abstract
An air liquification system for a combustor or the like, including a condenser having an air intake and a heat exchanger for cooling the air to substantially a liquid state. A first conduit conducts the liquid air to the combustor. A source of hydrogen in a liquid state is provided, and a second conduit conducts the liquid hydrogen to the heat exchanger whereby the hydrogen acts as the cooling medium therein. A third conduit conducts the hydrogen from the heat exchanger to the combustor and includes a compressor for compressing the hydrogen up to a given combustor pressure. A second combustor may be provided for operating at ambient air pressure, with a portion of the hydrogen from the condenser being conducted to the second combustor upstream of the compressor. An air precooler may be provided upstream of the heat exchanger for passing the liquid air therethrough to act as a regenerative cooling medium therein prior to conducting the air to the first combustor.
