    摘要: NOx exhaust emissions from furnace or boiler burners are reduced by combusting fuel with low excess air (about 5 percent more air than the theoretically required minimum air volume). The fuel is combusted so that the maximum flame temperatures are less than the theoretically obtainable maximum temperature. This is achieved by cooling flames in the chamber through contact with combustion chamber walls and by combusting central portions of the flames in two stages. Burners in a vertically lower burner bank are initially fired with insufficient air and burners in an upper burner bank are fired with additional air to make up for the air deficiency of the lower burners. The additional air is intermixed with the uncombusted fuel from the lower burners and such fuel is burned at a later stage downstream of and spaced from the burners. The additional air supplied from the burners in the upper row is measured to provide the above stated total of 5 percent excess air for the furnace.

    摘要: A fuel pump unit and burner combination, an air oil mixture being recirculated vertically upwards through a central blast chamber of said burner from there outwardly and downwardly through a surrounding chamber and then again through said blast chamber for preheating prior to combustion, a refractory ring and inversion cap being positioned in the surrounding chamber and spaced above the blast chamber said unit having means for delivering only low pressure primary air and oil at atmospheric pressure to said burner.

    摘要: In an embodiment, a method includes performing a turbine combustor diagnostic routine including operating a first turbine combustor of a plurality of turbine combustors at a substantially steady state of combustion; adjusting an operational parameter of the first turbine combustor to cause a change in combustion products produced by the first turbine combustor; identifying a first sensor response of a first subset of a plurality of sensors disposed within or downstream from a turbine fluidly coupled to the turbine combustor, the first sensor response being indicative of the change in the combustion products, and wherein the first subset comprises one or more first sensors; correlating the first subset of sensors with the first turbine combustor; and diagnosing a condition of the first subset of the plurality of sensors, the first turbine combustor, or a combination thereof, based on the first sensor response.

    摘要: A method for the combustion of ammonia, wherein a first combustion chamber receives ammonia and hydrogen in controlled proportions, and an oxygen-containing gas. Combustion of the ammonia and hydrogen produces NH2 ions among other combustion products. A second combustion chamber receives the combustion products from the first combustion chamber and receives further ammonia and further hydrogen in controlled proportions, wherein combustion produces nitrogen oxides among other combustion products. A third combustion chamber receives the nitrogen oxides along with further ammonia and further hydrogen in further controlled proportions along with further oxygen-containing gas, such that the nitrogen oxides are combusted into nitrogen and water.

    摘要: The pre-mix burner assembly includes a jet pump comprising a combustion air tube, a flue gas inlet, and a suction chamber. The combustion air tube has an inlet and a tapered nozzle, and it is connected to a combustion gas fan. The flue gas inlet is connected to the suction chamber and the furnace chamber or other flue gas source. The suction chamber surrounds the combustion air tube, and it has a jet pump nozzle with a discharge. The combustion air exiting the combustion air nozzle creates a negative pressure in the suction chamber and draws flue gas into the suction chamber. There is a burner housing positioned downstream of the jet pump discharge. There is a fuel gas inlet connected to a mixing tube in the burner housing, and a burner block connected to the outlet of the burner housing.
