A system and fuel system for supplying natural gas to thermal spray equipment

Abstract

Fuel modules are used to supply gaseous fuel at elevated pressure from relatively low pressure gaseous fuel sources such as natural gas supply systems to spray guns, thermal spray, fuel cells, thermal deburring, or fullerene manufacturing equipment. The fuel module may also include an alternatively operable alternative system for supplying such compressed natural gas for other applications, including a refueling facility for one or more storage vessels. The fuel module includes a feature by which its gaseous fuel discharge pressure can be infinitely varied and pre-selectively adjusted within the capacity of the fuel module's compressor equipment. The fuel module also includes features for cooling and filtering the oil from the compressor, which is cooled and filtered to prolong the life of the compressor and to enable operation of the fuel module under severe operating conditions at higher output gas pressures and more Performed under high output gas pressure.

Description

technical field [0001] The present invention generally relates to fuel cell equipment, thermal spray equipment, thermal deburring equipment, fullerene manufacturing equipment, and various torches or similar torches for cutting, welding or thermally processing metallic or non-metallic materials. More particularly, the present invention relates to a fuel device for supplying fuel to said fuel cell device, thermal spray device, thermal deburring device, fullerene manufacturing device and / or spray gun or similar spray gun device. The general term "welding" as used herein includes welding, brazing or other known process by which separate objects or pieces of material are joined to each other or Fusion. Background technique [0002] A fuel cell is a device that converts chemical energy into electrical energy (i.e. electricity) through a chemical reaction with oxygen or other oxidizing agents. Hydrocarbons (such as natural gas) can be used as fuel in some fuel cell devices (such ...

AI Technical Summary

Problems solved by technology

The supply of these fuels for the various processing methods described above tends to be very expensive and inconvenient in many applications because of the need to procure and ship such fuel pre-filled in storage containers, or to refill and ship pre-existing storage containers

Furthermore, these fuels often need to be supplied at different flow rates or at different pressures to spray guns or similar equipment, thermal spray equipment, thermal deburring equipment, fullerene manufacturing, because of different process pressures and other parameters related to the above process equipment or fuel cell equipment, thereby rendering the equipment incompatible or irreplaceable in some of the above operations
