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).
