摘要： A treatment system and method is disclosed for heat treating aggregate, for example, an aggregate dryer of the type which uses a burner and rotating drum for veiling aggregate into a thermal flow path. The invention provides a plurality of mixers which safely mix fuel and oxidant into a premix which is delivered to a reaction chamber The premix is combusted and recirculated within the reaction chamber to insure uniform and complete combustion, resulting in lower emissions of pollutants such as carbon monoxide, volatile organic compounds, and nitrogen oxides and also lower combustion roar. This uniform and complete combustion results in a more uniform thermal profile within the rotating drum, resulting a greater throughput of processed aggregate and a more efficient consumption of energy. The invention also includes a "tunability" feature for varying the delivery of fuel to the burner in order to avoid resonant vibration produced by a matching of the combustion frequencies with the natural frequency of the treatment system.

摘要： A burner is disclosed having a burner chamber with heavily insulated heat retaining walls and a series of off-center mixers located at one end thereof. A uniform concentration gas/air mixture to 50% additional fuel above the lean flammability limit coming from the mixer tubes is ignited in the burner chamber due to the recirculation of combusting gas and air back to the end of the burner chamber above auto the ignition temperature for the mixture. The particular mixture disclosed utilizes 0.55-0.7 equivalence ratio. With the present burner, oxidant and fuel are respectively supplied to each mixer by respective common oxidant and fuel plenums. In this way, fuel and oxidant are mixed near the point of combustion, enhancing safety and permitting the construction of larger burners.

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 NOx 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 flow of air is provided from a hot air main into a combustion chamber at a time when a burner is firing into the combustion chamber to heat a bed of regenerative media. The flow of air into the combustion chamber helps to keep products of combustion from flowing into the hot air main. In preferred embodiments, sensors sense pressure in the combustion chamber and the hot air main. A controller shifts a valve back and forth within a range of open conditions to regulate the flow of air in response to the sensed pressures.
