Abstract: A baffle for a regenerative burner has a primary reactant port, secondary reactant ports, and internal flow paths. The primary port is centered on an axis. The secondary ports are arranged in an array that is asymmetrical relative to a plane containing the axis. The internal air flow paths convey secondary air streams from the regenerative bed to the secondary ports. A reactant delivery structure for use with the baffle includes a pilot burner, a main fuel conduit, and a primary air conduit. The pilot burner projects a pilot flame toward the primary port. The main fuel conduit has an annular outlet that directs a main fuel stream over the pilot flame and outward from the primary port. The primary air conduit has an annular outlet that directs a primary air stream outward from the primary port over the main fuel stream.

Abstract: An actuated air valve includes a valve body in line with a flow passage for admitting a flow of fluid. A valve member is pivotally mounted about the centerline of the valve body and is pivoted between high flow and low flow positions. A diaphragm and linkage is in mechanical connection to the valve member. A pressure tap from the flow of fluid provides an impulse to the diaphragm which displaces the linkage, thus varying the position of the valve member. A three-way solenoid valve is used to selectively admit the impulse to the diaphragm, thus governing the displacement of the linkage, and thereby varying the position of the valve member.
