Abstract
A tank is configured to store a supply of cryogenic liquid and a heat exchanger has a main line and a reheat line. A liquid pickup line directs cryogenic liquid from the tank to the main line of the heat exchanger. A trim heater exit tee receives fluid from the main line of the heat exchanger. Fluid exits the trim heater exit tee through an engine outlet and a trim heater outlet. Fluid exiting through the engine outlet flows through a flow restriction device and to a primary inlet of a trim heater return tee. A trim heater line receives fluid from the trim heater outlet of the trim heater exit tee and directs it to the reheat line of the heat exchanger after the fluid passes through a portion of the trim heater line positioned within the tank. Warmed fluid leaving the reheat line of the heat exchanger travels to a trim heater inlet of the trim heater return tee.
