摘要： A catalytic tank heater includes a catalytic heating element supported on an LPG tank by a support structure that holds the element in a position facing the tank. Vapor from the tank is provided as fuel to the heating element, and is regulated to increase heat output as tank pressure drops. The heating element is internally separated into a pilot heater and a main heater, with respective separate fuel inlets. The pilot heater remains in continual operation, but the main heater is operated only while tank pressure is below a threshold. Operation of the pilot heater keeps a portion of the catalyst hot, so that, when tank pressure drops below the threshold, and fuel is supplied to the main heater, catalytic combustion quickly expands from the area surrounding the pilot heater to the remainder of the catalyst.

摘要： Disclosed herein is a pressure control system for a liquid natural gas (LNG) storage tank. The pressure control system comprises a second heat exchanger, comprising a first inlet fluidly coupled with the LNG storage tank and a first outlet fluidly coupled with the LNG storage tank. The pressure control system also comprises a coolant, fluidly coupled with a second inlet of the second heat exchanger. The heat exchanger is configured to transfer energy from the coolant to the LNG from the LNG storage tank to vaporize the LNG into compressed natural gas (CNG). The pressure control system also comprises a first control valve selectively operable to allow LNG to flow from the LNG storage tank to the heat exchanger and to allow CNG to flow from the heat exchanger to the LNG storage tank when a pressure within the LNG storage tank is below a lower pressure threshold.

摘要： A cryogenic tank system includes a plurality of heat exchangers for heating an interior volume of a storage container. Heat transfer to the interior volume of the storage container by the plurality of heat exchangers pressurizes the interior volume of the storage container. The system further includes a valve assembly mounted to the storage container and positioned substantially within the storage container. The valve assembly includes an inlet portion and an outlet portion. The outlet portion is positioned outside of the storage container, and the inlet portion is positioned within the storage container. The inlet portion is sealable by a fail-closed powered sealing mechanism.

摘要： A method for starting gas delivery from a liquefied gas fuel system includes a fuel tank filled with liquefied gas by a filling procedure and the filling procedure resulting in the pressure in the tank being at least at an operational pressure required by the engine. The method pressure in the tank is controlled by controlling the operation of a pressure build up system including the pressure build up evaporator which is arranged in a conduit leading from the bottom section of the tank to the upper section of the tank. The pressure build up system is controlled by controlling the flow rate of the evaporated gas in the conduit while the heat transfer medium is allowed to flow unconstrained through the pressure build up evaporator.
