Abstract: A submerged combustion melting system (90) includes a submerged combustion melter (100) having a housing with one or more side walls (104), a floor (106), and a ceiling (108) which at least partially define a melt chamber (110). The melter has one or more main burners (128) positioned along the floor of the housing and an oxygen/gas burner in a preheat burner system (300) removably attached to one of the sidewalls or the ceiling, the oxygen/gas burner arranged such that a flame from the oxygen/gas burner is directed downward into the melt chamber.

Abstract: A flow meter device that improves a way to obtain an accurate differential pressure across an orifice body situated in line with the flow of gas and liquids. The orifice body is held in place by sealing components integrated into the orifice body. The differential pressure is sensed via openings incorporated into the body of the device, upstream and downstream of the orifice body. The device with its improved accuracy may be used for small and large applications measuring flow. The device is comprised of a meter body; an orifice puck with characteristics; a sealing method; a cover plate, and a way to secure the device into a fluid stream where the device may be used to easily and accurately measure fluid flow in a pipe.

The device 31 is comprised of a meter body 32; an orifice disk 43 with features; a sealing means 50; a cover means 33, and a means to secure the device 31 into a fluid stream where the device 31 may be used to easily and accurately measure fluid flow in a pipe.

Abstract: A burner (10, 210) is provided in accordance with the present invention that includes an outer tube (62), an inner tube (34) positioned to be within the inner tube (34), a power supply (38) coupled to the inner tube (34), and an ignitor pin (70) coupled to the outer tube (62). An insulator (16) is provided that separates the burner (10) from a natural gas supply (28). The natural gas supply (28) provides natural gas to a combustion zone (45) through the inner tube (34). An oxygen supply (58) provides oxygen to the combustion zone (45) through a gap (144) between inner and outer tubes (34, 62). A spark is created between the inner tube (34) and the ignitor pin (70) to ignite the natural gas and oxygen to create a flame (12).
