Cryogenic pump system for converting fuel

摘要

A system for converting liquid fuel into gaseous fuel is provided. The system may have a supply of liquid fuel. The system may also have a combustor, and one or more pumps in fluid communication with the supply. The one or more pumps may be configured to pump liquid fuel from the supply into the combustor. The system may also have a compressor in fluid communication with an inlet of the combustor, and a turbine in fluid communication with an outlet of the combustor. The turbine may be connected to drive the compressor and the one or more pumps. The system may also have a heat exchanger in fluid communication with an outlet of the turbine and an outlet of the one or more pumps.

1. A system for converting liquid fuel into gaseous fuel, comprising:
a supply of cryogenic liquid fuel; a combustor, the combustor including a cryogenic liquid fuel combustion chamber configured for combusting a fuel/air mixture derived from the liquid fuel without having to first gasify the liquid fuel; one or more pumps in fluid communication with the supply and configured to pump the liquid fuel from the supply into the combustor in liquid form; a compressor in fluid communication with an inlet of the combustor; a turbine in fluid communication with an outlet of the combustor to receive heated exhaust flow from the combustor and connected to drive the compressor and the one or more pumps; and a heat exchanger in fluid communication with an outlet of the turbine to receive the heated exhaust flow from the turbine, and in fluid communication with an outlet of the one or more pumps and an outlet of the heat exchanger in fluid communication with an inlet of the combustor to supply the heated exhaust flow into the liquid fuel upstream of the combustor.
