Gaseous fueled torch apparatus and fueling module therefor
This patent describes a fueling module for supplying natural gas to a natural gas fueled torch apparatus including a torch adapted for use in cutting or welding operations, the torch apparatus further including a source of oxygen for supplying oxygen to the torch, and the torch being selectively operable for combustion of a mixture of natural gas and oxygen, the fueling module connectable to an electric power source and being supplying natural gas to the torch apparatus at an elevated pressure from a relatively low pressure natural gas supply system, the fueling module comprising: fueling module inlet means connectable in fluid communication with the natural gas supply system; compression means in fluid communication with the fueling module inlet means and selectively energizable for compressing the natural gas from the natural gas supply system in order to increase its pressure, the compression means having a compression intake in fluid communication with the fueling module inlet means and a compression discharge outlet for discharging compressed natural gas from the compression means; lubricant filter means in fluid communication with the compression discharge outlet for substantially trapping and collecting compression means lubricants from the compressed natural gas from the compression discharge outlet and for returning the collected compression means lubricants to the compression intake; cooling means in fluid communication with the compression discharge outlet means for reducing the temperature of the compressed natural gas.
