Abstract
Pneumatic control of flow patterns in regenerators is improved by the use of flow amplifier nozzles.
Claims22
A method of operating a regenerative furnace wherein gases are passed through passageways between a combustion chamber and a regenerator bed, injecting a jet of gas into a moving stream of gas in at least one of the passageways so as to affect movement of the stream and to thereby alter the flow pattern of gases between the combustion chamber and the regenerator bed, the jet being a narrow, high velocity jet discharged adjacent to a nozzle surface to flow along the surface and entrain gas within the passageway.
A method of operating a regenerative furnace wherein gases are passed through a passageway between a flue and a regenerator bed which is in communication with a combustion chamber, injecting a jet of gas into a moving stream of gas in the passageway so as to effect movement of the stream and to thereby alter the flow pattern of gas through the regenerator bed, the jet being a narrow, high velocity jet discharged adjacent to a nozzle surface to flow along the surface and entrain gas within the passageway.
