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.

Aerodynamic device for increasing the flickering of a natural gas flame

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.

Slotted burner for gas fireplace

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.

Control methods and apparatus for gas-fired combustors

A pulse combustion space heater and burner are disclosed. The heater has an exterior cabinet enclosing an interior housing having the burner mounted therein. The burner includes a plurality of generally flat elements which cooperate with the interior housing to provide a tortuous path for air circulated through the chamber during heat transfer. A labyrinthine air flow passageway lined with sound attenuating material is provided immediately upstream of the heater air discharge. The burner tailpipe comprises a weldment of two identical sheet metal pieces which cooperatively define a tailpipe conduit. A fuel gas inlet orifice is mounted in the wall of the mixer head to effect both regulation of the average flow rate and injection of the fuel to enhance its mixture with the air.
