embodiment 70

[0039]FIG. 6 discloses an alternate preferred embodiment 70 of the burner apparatus 10. The arrangement is similar to that in FIGS. 1 through 5 with the exception of the introduction of the secondary fuel gas and secondary tail gas or waste gas in conjunction with an alternate arrangement of refractory tile 62. In the alternate embodiment shown in FIG. 6, the secondary fuel gas delivered through secondary fuel gas line 60 mixes with the secondary tail gas or waste gas through secondary waste gas pipe or pipes 50 and then simultaneously mixes with the combustion air, primary fuel gas and primary waste gas.

embodiment 80

[0040]FIG. 7 illustrates a further, alternate preferred embodiment 80 of the present invention. The alternate embodiment shown in FIG. 7 is similar to the arrangement of the foregoing with the exception of the secondary fuel gas and secondary waste gas introduction in conjunction with a further alternate arrangement of refractory tile 72. In the alternate embodiment shown in FIG. 7, the secondary tail gas or waste gas delivered through secondary waste pipe 50 fully or partially mixes with the secondary fuel gas delivered through secondary fuel gas line 60 prior to or before mixing with the combustion air, primary fuel gas through primary fuel gas line 40 and primary waste gas from the primary waste gas pipe or pipes 30. The arrangement disclosed in FIG. 7 will tend to minimize NOx emissions.

[0041]Whereas, the devices and methods have been described in relation to the drawings and claims, it should be understood that other and further modifications, apart from those shown or suggeste...

Abstract

A high efficiency low NOx emission thermal oxidizer burner apparatus. The apparatus includes a plenum chamber having an inlet for introduction of combustion air and includes a combustion chamber in fluid communication with the plenum chamber. A primary waste gas pipe terminates in a lobed tip nozzle through the plenum chamber for introduction of waste gas into the combustion chamber. A primary fuel gas line is in communication with the plenum chamber for introduction of primary fuel gas.

Description

1. FIELD OF THE INVENTION[0001]The present invention is directed to a high efficiency low NOx emission burner apparatus and method. In particular, the present invention is directed to a thermal oxidizer burner apparatus and method which utilizes waste gas or tail gas from an independent source to achieve high efficiency and low emission of nitrogen oxides.2. DESCRIPTION OF THE RELATED ART[0002]Oxides of nitrogen form as a result of combustion emitting from burners. Various prior configurations and designs have been utilized in the past to increase the efficiency of thermal oxidizer burners and to reduce nitrogen oxides content of the flue gas effluent, There are a variety of oxides of nitrogen in flue gas effluent, such as nitrogen oxide (NO), nitrogen dioxide (NO2) and others which arc together generally labeled NOx.[0003]It is known that high oxygen content can increase the formation of nitrogen oxides. It is also known that increasing combustion temperatures may increase producti...
