摘要： A method heats a furnace process chamber with the combustion of fuel gas. The method heats the process chamber in a preheat mode when the temperature of the process chamber is below the autoignition temperature of the fuel gas. The preheat mode forms preheated combustion air by directing the combustion air through a regenerative bed. A stream of the preheated combustion air is directed into the process chamber in a condition unmixed with fuel gas. The preheat mode also forms a fuel rich mixture of the fuel gas and unheated combustion air. The fuel rich mixture is directed into the process chamber adjacent to the stream of preheated combustion air.

摘要： A method of using internal combustion engine exhaust in a combined cycle power plant is disclosed, wherein the quality and distribution of exhaust to the boiler space of a steam generated electric power plant is controlled to achieve greater system efficiencies. Outside air is blended only with that portion of the exhaust that passes through the burner ports as secondary or higher level combustion gas. The remainder of the exhaust is provided to the boiler space by a route other than through the burner. The highest overall system efficiencies are achieved where the amount of outside air blended with the portion of exhaust that passes through the burner is such that the blend contains about the minimum amount of oxygen required for complete and stable combustion of the selected fuel, where a substantial percentage of the total exhaust is routed to the boiler space by a route other than through the burner, and where the amount of fuel is sufficient to achieve a desired boiler entering temperature upon its combustion.

摘要： A device for an oil burner has a ceramic tube (1) inside which a shorter tube (61) is arranged, so that there is a slot between the tubes. The device stands freely in the combustion room of the boiler, and it is coaxial with an oil burner (66) that is mounted in the boiler room wall. Combustion fumes mixed with fresh air from the fan of the oil burner is sucked into the slot that ends inside the ceramic tube. The oil burner flame in the inner tube (61) heats this inner tube that in turn heats the air that is sucked through the slot and is secondary combustion air. The slot has screw-formed ridges that impart a heavy rotation to the secondary air; a rotation that is counter to the rotation of the primary air of the burner. Since the secondary air is hot and rotates heavily, the final combustion will be very efficient.

摘要： Past systems have attempted to provide a combustion system to reduce NOx pollution, however, such methods have failed to attain adequate reductions in NOx pollution. The present system or structure for for reducing NOx includes a pilot fuel system and a premixed supply system to reduce the NOx to a workable level. The pilot system uses a device for supplying combustible fuel to the fuel injection nozzle generally along a combustion axis during all or a portion of the operating conditions of the engine. Low NOx is maintained by using a device for supplying combustible fuel into each of a plurality of spaces formed between a plurality of swirler vanes. Low NOx is further maintained by having the cooling fluid used to cool the fuel injection nozzle mixed with the fuel and air from the spaces prior to entering the combustion chamber.

摘要： A gas burner is described having a cylindrical combustion chamber having at least two spaced apart counter-rotation stationary tangential air injectors and at least three sets of radial injection holes in between for admitting air under pressure in the combustion chamber to cause adjacent counter-rotation air turbulence regions in said combustion chamber. The combustion chamber has a closed end and an open end with a gas injector tube extending in the chamber from the closed end and disposed centrally therein. The injector tube has combustion gas injection ports at least upstream and downstream of the at least two air injectors to create a combustion mixture which is initially fuel-lean to generate a flame having a lower temperature and producing less nitrogen oxide than with conventional gas burners of this type. An air chamber is provided about at least a portion of the combustion chamber and communicates with the tangential air injectors.
