Abstract
A fuel system for a liquefied gas drive system. The fuel system has a liquefied gas tank and a cooling system for the vaporized content of liquefied gas, which comprises a liquid nitrogen tank, a nitrogen pump, a heat exchanger, and a nitrogen cooler, which are connected to each other in a pipework circuit. The heat exchanger is arranged in the interior of the liquefied gas tank. Also disclosed are a vehicle, a plant and a machine, in each case with a fuel system, and a method for cooling the vaporized content of liquefied gas of a liquefied gas drive system.
Claims13
A fuel system for a liquefied gas drive system, comprising:
- a liquefied gas tank;
- and
- a cooling system,
- wherein the cooling system comprises a liquid nitrogen tank, a nitrogen pump, a heat exchanger, and a nitrogen cooler, which are connected to each other in a pipework circuit, and
- wherein the heat exchanger is arranged in an interior of the liquefied gas tank,
- further comprising at least one extraction system with a flue, to which the liquefied gas tank is connected via at least one pipe configured to discharge gas from the liquefied gas tank through the flue,
- wherein at least one of:
- the cooling system further has at least one of an outlet that is likewise connected to the flue and that can be closed or opened for discharging nitrogen heated in the heat exchanger through the flue, or a pressure relief outlet connected to the flue to limit a maximum pressure in the pipework circuit by discharge through the flue, or
- the fuel system further comprises a nitrogen purge system connected to the flue to feed nitrogen into the flue.
