    Abstract: Certain embodiments of a nozzle are configured to dispense a first gas, liquid, or combination thereof at a first pressure in a first mode of operation and dispense a second gas, liquid, or combination thereof at a second pressure in a second mode of operation. In some embodiments, the nozzle is integrated in a heat-producing device, such as, for example, a heater, a fireplace, or a stove. In some embodiments, the heat-producing device including the nozzle can operate with a first combustible fuel at a first pressure, or alternatively, can operate with a second combustible fuel at a second pressure. In some embodiments, the nozzle is used in applications other than heat-producing devices.

  • Patent number: 7008218
    Abstract: There is described a method and apparatus for controlling the combustion by-product formation rate in at least one burner of a fossil fuel fired power plant. The burner has an associated flame scanner which is focused on a small area of the burner flame to obtain an image signal of the flame. A flame signal that represents properties of temporal combustion in the visible light spectrum of the burner is generated from the image signal. Combustion turbulence at the burner is analyzed from the flame signal by a dynamic invariant that has a relationship to the combustion by-product values and different combustion by-product levels at the burner and the combustion turbulence is correlated to the combustion by-product formation rate at the burner. The method and apparatus can also be used to correlated the combustion turbulence at a multiplicity of burners to the associated combustion by-product formation rate.

  • Patent number: 6881055
    Abstract: A system for controlling temperature in an enclosure operates in a low heat or a high heat mode with flame always present. The presently intended use is for providing a cooking grill with a controlled temperature cooking space. An electrically controlled valve having high flow rate and low flow rate settings is interposed in the fuel line for at least one of the burners in the grill. A temperature sensor signals cooking space temperature to a controller that may be a microprocessor. The system includes a keyboard allowing the user to communicate a selected set point to the microprocessor and the microprocessor communicates status to a display. The microprocessor selects the setting of the electrically controlled valve. In a preferred embodiment, the electrically controlled valve is placed in series fuel flow with one of the manually adjustable valves commonly found on cooking grills.

  • Patent number: 6758208
    Abstract: A compact, highly flexible and efficient, multi-positionable, multi-dimensional and multi-stage gas-fired heat exchanger system as described. The system is connectable in a forced air duct regardless of the angular position and size of the duct. The heat exchanger comprises one or more heat transfer tubes which are shaped and dimensioned as dictated by the customized use of the heat exchanger. The tubes are secured to a support panel as well as the gas burner associated with each of the inlet openings of the tubes. A position orientable gas valve is secured to a gas distribution manifold. A turbulator may be associated with at least some of the tubes to cause turbulence in the hot combustion flow in each of the tubes to modify the efficiency in heat transfer along one or more sections of the tubes by directing hot combustion gas along an inner circumferential wall of the tubes.
