US Patent:

58197257, Oct 13, 1998

Filed:

Feb 28, 1996

Appl. No.:

8/608243

Inventors:

Robert A. Borgeson - Cleveland Heights OH

Assignee:

Gas Research Institute - Chicago IL

International Classification:

F23C 118
F23C 1104

US Classification:

126512

Abstract:

A process and apparatus for combustion of a gaseous fuel in a fireplace in which a plurality of periodic vortices are created in the airflow pattern of the combustion air prior to its mixing with the gaseous fuel, thereby producing a more natural looking, flickering flame.

Assignee:

Gas Research Institute - Chicago IL

International Classification:

F23D 1446

US Classification:

431 8

Abstract:

A method and apparatus for producing a gas-fired flame which simulates a wood-burning flame. The apparatus includes an elongated slot which is port loaded to produce a buoyancy controlled flame which flickers and closely resembles a wood-burning flame.

International Classification:

F24H 300

US Classification:

126116A

Abstract:

A control system for a fluid-fuel burner, such as a furnace for an HVAC system. The furnace has a variable flow of fuel into the burner. In addition, the circulating air blower is also variable. The furnace heat exchanger plenum is maintained at a substantially constant temperature, as a means for providing substantially constant temperature air to the spaces to be heated.

International Classification:

F23C 5/00
F24H 3/00

US Classification:

431 8, 126116 R

Abstract:

Premix furnace for heating an occupied space while producing lower NOx emissions and methods of mixing air and fuel delivered to a premix burner and of improving combustion stability. A mixing device may be located within an inlet tube, may have a flat surface that is perpendicular to the direction of fuel flow, or may have two surfaces held at substantially opposite angles to induce swirl. A mixing device may be attached to the fuel injector, may be made from a piece of sheet metal, and may have bends and a hole for attachment to the fuel injector. A fluidic diode in the inlet tube may improve combustion stability and may include a hollow frustum or a frustoconical portion, a cylinder concentric with the inlet tube, or a combination thereof. Some embodiments include refractory insulation lining the combustion chamber or may adjust for elevation or fuel characteristics.
