Abstract:
A burner (10) for use in both high O. sub. 2 environments and low O. sub. 2 environments comprises an outer tube (24) and an inner tube (26). The outer tube (24) defines a flow passage (53) and includes an inlet portion (42), an outlet portion (46), and a nozzle portion (44) interconnecting the inlet portion (42) and outlet portion (46). The inlet portion (42) has a larger effective cross-sectional area than the outlet portion (46) so that air (20) or an air-and-fuel mixture (35) moving through nozzle portion (44) is accelerated. The inner tube (26) is positioned to lie in the flow passage (53) of the outer tube (24) and is formed to include fuel-injection holes (78) to conduct fuel (33) into the flow passage (53).
