A reciprocating piston cryogenic pump has been suspended from stroking when process fluid discharge temperature from a vaporizer dropped below a threshold to prevent freezing of a heat exchange fluid circulating through the vaporizer and damage to downstream components. Suspension of the pump results in a decrease of process fluid pressure downstream of the vaporizer, which is undesirable. In the present technique, a temperature is monitored correlating to process fluid temperature downstream of the vaporizer. The amount of process fluid discharged from the pump in each cycle is adjusted as a function of the temperature such that the average residence time of the process fluid in the vaporizer is increased as the discharge amount decreases, increasing process fluid discharge temperature. The average mass flow rate of the process fluid through the vaporizer is unchanged regardless of pump discharge amount such that process fluid pressure downstream of the vaporizer is maintained.

A quick-disconnect gas pipeline comprises a quick-disconnect device (QDD) which comprises a QDD male end and a QDD female end, and a gas hose. The QDD male end is connected to the gas pipeline inside the heating system and the QDD female end is connected to the gas hose outside the heating system. When the heating system is not used, it is easy to disconnect the QDD to prevent people from tripping over the long gas pipeline.

The heater block of the present disclosure can transfer heat from a heat transfer fluid to a received fuel fluid, air passing in proximity to the heater block or combinations thereof. These heat transfers reduce, substantially prevent or prevent the freezing of water within the received fuel fluid and/or the air as it enters an intake member of a gas burning unit.

The present invention consists of a saving gas device which, being placed downstream of the pressure regulator and upstream of the consuming devices, in a natural gas or liquefied petroleum gases supply facility, improves the gas consumption efficiency by means of a recirculation, filtering and centrifugation process. The action exerted on the steam trap of the device, retains the impurities the gas contains, thus improving retention of particles and achieving the gas to come out substantially pure, as well as achieving gas molecules rearrangement by means of a centrifugation coil, obtaining flow stabilization and improving the circulation thereof.

A hydrogen powered cooker burner is provided, having an inlet duct for the hydrogen through a burner body connected to the inlet duct up to a flame spreader. A sealed fluidic hydrogen connection is made by a nozzle coupled to a nozzle holder. In an embodiment, the nozzle has a second thread opposite a first thread. The cooker burner has a tubular sealing tie rod provided with a thread and sealing surfaces. The tubular sealing tie rod is configured so that, while screwing, the sealing surfaces of the tubular sealing tie rod are forced against an element of the burner.

The fuel preheater includes a first mixer provided in a fuel supply line connected to a combustion facility that combusts fuel including ammonia, the fuel supply line supplying ammonia to the first mixer, the first mixer being connected to an oxidizer supply line that supplies an oxidizer and mixing the ammonia flowing in the fuel supply line with the oxidizer from the oxidizer supply line to produce a mixed gas, and a reactor provided downstream of the first mixer in the fuel supply line, the reactor including a catalyst that promotes a reaction of the ammonia and that causes an exothermic reaction, the catalyst causing the exothermic reaction with at least a part of the ammonia in the mixed gas that is supplied from the first mixer and heating the mixed gas.
