摘要： An indurating furnace has a heating station and an air passage leading to the heating station. A draft of preheated recirculation air is driven through the passage toward the heating station, and is mixed with fuel gas to form a combustible mixture of preheated recirculation air and fuel gas that ignites in the passage. This is accomplished by injecting the fuel gas into the passage in a stream that does not form a combustible mixture with the preheated recirculation air before entering the passage.

摘要： A NOx suppression apparatus is configured for use with a burner that injects fuel into a stream of process air flowing into and through a rotary kiln. The apparatus comprises a premix injection system that forms a premix of fuel gas and air, and injects the premix into the stream of process air upstream of the burner port. This enables premix products of combustion to suppress the production of NOx by vitiating a combustion air portion of the process air before the combustion air portion combusts with fuel injected from the burner port.

摘要： A low NOx burner and related method are disclosed including the steps of supplying a first reactant stream and introducing a second reactant stream into the first reactant stream at a first point so as to produce co-flowing streams. This resulting fuel/oxidant stream is discharged into a furnace environment having inert combustion products substantially equilibrated to furnace temperature, so as to entrain the combustion products and mix them together with the co-flowing stream. The temperature of the co-flowing stream is increased by the entrained products until it ignites in a combustion region displaced from the first point. Thus ignition cannot occur until the reactant stream has been diluted by inert products of combustion, reducing both oxygen concentration and peak flame temperature, so as to suppress NOx production.
摘要翻译：公开了一种低NOx燃烧器和相关方法，其包括以下步骤：在第一点处供应第一反应物流并将第二反应物流引入第一反应物流中，以产生共流。将所得到的燃料/氧化剂流排放到具有基本平衡于炉温的惰性燃烧产物的炉子环境中，以便夹带燃烧产物并将它们与共同流动物料混合在一起。共同流动的温度由夹带的产物增加，直到其在从第一点移位的燃烧区域中点燃。因此，直到反应物流被惰性惰性产物稀释后才能发生点火，降低氧气浓度和峰值火焰温度，以抑制NOx的产生。

摘要： A method of combusting non-gaseous fuel to heat a load in a process chamber includes the steps of injecting reactant streams into a combustion chamber. The combustion chamber does not contain a load to be heated, but communicates with the process chamber through a burner port. A first reactant stream includes the non-gaseous fuel, and is injected into the combustion chamber to cause the non-gaseous fuel to volatilize in the combustion chamber. A second reactant stream, which includes a premix of gaseous fuel and primary oxidant, also is injected into the combustion chamber. The first and second reactant streams then combust together to yield products of combustion that flow through the burner port from the combustion chamber to the process chamber. Importantly, the second reactant stream is injected into the combustion chamber adjacent to the first reactant stream. This causes the second reactant stream to adjoin the first reactant stream at the onset of volatilization of the non-gaseous fuel, which is found to inhibit the production of NOx.
