A cooking appliance and method of operating the same utilize a variable electromechanical valve to regulate an output power level of an oven broiler gas burner for a cooking appliance. Among other benefits, in some instances broiler control during cooking may be decoupled from oven warm-up, and in some instances support may be provided for automatic and/or user controlled broiler output power levels and/or automated broil profiles.

The present disclosure relates to systems and methods that are useful for controlling one or more aspects of a power production plant. More particularly, the disclosure relates to power production plants and methods of carrying out a power production method utilizing different fuel chemistries. Combustion of the different fuel mixtures can be controlled so that a defined set of combustion characteristics remains substantially constant across a range of different fuel chemistries.

An assembly for injecting a gaseous combustion agent into a combustion zone, the assembly having a chamber having an inlet, through which the agent is introduced into the assembly; at least one primary injector configured to convey a primary flow of the agent from the chamber toward the combustion zone, at least one secondary injector for conveying a secondary flow of the agent from the chamber toward the combustion zone, a pressure detector; a regulating; and a control system connected to the pressure detector and to the regulating system, the control system controlling the regulating system so that the flow section of the at least one secondary passage is regulated as a function of the pressure or of the variation in pressure detected by the pressure detector.

A hydrogen chloride loop fuel reaction is designed and configured for turbine/generator combination which can be used for automotive propulsion or as a standalone electrical generation or for auxiliary equipment. A method for providing a hydrogen chloride loop fuel reaction includes creating hydrogen chloride fuel in a sealed furnace vessel, wherein at start up, the sealed furnace vessel is vacuumed out and hydrogen and chlorine are injected into a burner and ignited resulting in the hydrogen chloride fuel in an exhaust stream of the sealed furnace vessel; and looping the hydrogen chloride fuel leaving the sealed furnace vessel in the exhaust stream of the sealed furnace vessel.

The premixing device includes a first and a second venturi having a pressure reducing portion for air, and a gas supply passage for supplying fuel gas to the venturis, and generates air-fuel mixture by mixing fuel gas with air flowing in the venturi by using a fan and supplies the air-fuel mixture to a burner. A first and a second nozzles for reducing pressure of fuel gas are disposed in the gas supply passage, and the first and the second nozzles are formed in the same nozzle shape as the pressure reducing portion of the first and the second venturis.

The invention relates to a system for treating hydrogen and/or oxygen gas produced by water electrolysis and serving to supply a combustion process, characterised in that it comprises at least one heat exchanger, in which the one or more gases circulate so as to be cooled or heated, said heat exchanger being submerged in a reactive compound through which the one or more gasses pass in turn.

The present invention is a system that utilizes high pressure gas (greater than ½ psig) to control flow rate and gas discharge velocity to enable interchangeability between a plurality of gases without having to change the gas/air mixing venturi size or air opening. A new approach is to use the available incoming higher gas pressure to the appliance then control the volumetric flow rate with the first orifice and then use a second orifice to change the velocity of discharge into the gas/air mixing venturi of the burner and therefore have adjustability of gas air mixing conditions without having to change the burner system or air flow control even when changing between very different fuel gases.

A charging system for charging a reactor with air used energy produced by the reactor and includes a vessel having a hollow interior cavity partially filled with a liquid slug, a first air pocket within the cavity on a first side of the liquid slug, and a second air pocket within the cavity on a second side of the liquid slug. The liquid slug forms a water trap seal in the cavity between the two pockets and moves within the vessel in a cycle in which gas is loaded into the first air pocket in a first stroke and gas in the first air pocket is compressed in a second stroke. Movement of the liquid slug during the second stroke is caused by an increasing pressure in the second air pocket due to introduction of high-pressure gas from the reactor into the second air pocket.

A burner includes a distal flame holder, first and second fuel nozzles, a fuel and oxidant source, and a mixing tube disposed upstream from the distal flame holder. Fuel emitted from the first fuel nozzle mixes with oxidant from the oxidant source to form a fuel and oxidant mixture to support combustion in the distal flame holder. A non-reactive fluid source such as recirculated flue gas provides a non-reactive fluid for dilution of the fuel and oxidant mixture to prevent flashback.
