摘要： A grate-kiln pelletizing furnace includes a grate that conveys pelletized material to a rotary kiln, a cooler that cools pelletized material from the rotary kiln, and a gas flow apparatus that directs a stream of gas from the cooler to the rotary kiln to provide preheated process air for pelletized material in the rotary kiln. The gas flow apparatus also directs a stream of gas from the grate to the rotary kiln to vitiate the preheated process air.

摘要： A method directs fuel-oxidant premix into a reaction zone through a first total premix inlet flow area, and causes the premix to combust and form a stable flame projecting into a process chamber through an outlet from the reaction zone. At a time when the process chamber has a temperature at or above an auto-ignition temperature of the fuel, the flame is blown off to initiate diffuse combustion in the process chamber without a stable flame. The flame is blown off by directing the premix into the reaction zone through a second total premix inlet flow area greater than the first total premix inlet flow area.

摘要： A method delivers fuel gas to a furnace combustion chamber from a premix burner having a reaction zone with an outlet to the furnace combustion chamber. This includes the steps of injecting a premix of primary fuel gas and combustion air into the reaction zone, and combusting the premix to provide combustion products including vitiated combustion air in the reaction zone. Further steps include injecting staged fuel gas into the reaction zone separately from the premix, discharging the staged fuel gas and vitiated combustion air from the reaction zone through the outlet to the furnace combustion chamber, and combusting the staged fuel gas and vitiated combustion air in the furnace combustion chamber. This enables low NO x combustion in the furnace combustion chamber to be achieved as a result of interacting the staged fuel gas with the vitiated combustion air in the reaction zone.

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.
摘要翻译：燃烧非气体燃料以加热处理室中的负载的方法包括将反应物流注入燃烧室的步骤。燃烧室不包含要加热的负载，而是通过燃烧器端口与处理室连通。第一反应物流包括非气体燃料，并且被注入到燃烧室中以使非气态燃料在燃烧室中挥发。包括气体燃料和初级氧化剂的预混物的第二反应物流也被注入到燃烧室中。第一和第二反应物流然后燃烧在一起以产生燃烧产物，该产物从燃烧室流过燃烧器端口至处理室。重要的是，将第二反应物流注入与第一反应物流相邻的燃烧室。这导致第二反应物流在非气态燃料的挥发开始时与第一反应物流相邻，这被发现抑制了NOx的产生。

摘要： A method of firing a burner into a furnace process chamber supplies the burner with fuel and combustion air at a ratio that provides a level of excess air. The method includes the steps of reducing the flow rate of combustion air, and maintaining the level of excess air when the flow rate of combustion air is being reduced. Other steps include withdrawing exhaust gas from the process chamber, and supplying the burner with the exhaust gas at an increasing flow rate when the flow rate of combustion air is being reduced.

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 directs fuel-oxidant premix into a reaction zone through a first total premix inlet flow area, and causes the premix to combust and form a stable flame projecting into a process chamber through an outlet from the reaction zone. At a time when the process chamber has a temperature at or above an auto-ignition temperature of the fuel, the flame is blown off to initiate diffuse combustion in the process chamber without a stable flame. The flame is blown off by directing the premix into the reaction zone through a second total premix inlet flow area greater than the first total premix inlet flow area.
