Benefits of technology

[0015]The fuel injection assembly of the second aspect of the burner assembly is adapted to inject fuel into the furnace from one or more fuel tips located outside of the burner throat. The fuel injection assembly includes a main fuel tip and a main fuel riser for injecting main fuel into an ignition zone located within the furnace

Problems solved by technology

Unfortunately, in some applications, the admixture of primary fuel with combustion air in the throat of the burner can generate temperatures therein that are high enough to allow nitrogen oxides to form.
Combining a relatively high concentration of oxygen in

Embodiment Construction

[0048]Referring to the drawings, the inventive burner assembly is illustrated and generally designated by the numeral 10. As shown by the drawings and understood by those skilled in the art, the burner assembly 10 and components thereof are designed to be associated with a furnace 12 (the overall furnace is not shown) and can be used to generate heat in a petroleum refinery, chemical plant or other applications. The burner assembly 10 is attached to a wall 14 of the furnace 12 (for example, a side wall, bottom wall (or floor) or top wall (or ceiling)) and extends into a furnace space 16 of the furnace. The burner assembly 10 can also freely stand in the furnace 12, for example on the floor of the furnace. The furnace wall 14 includes an internal layer of insulating material 14(a) attached thereto.

[0049]The burner assembly 10 shown by FIGS. 1 and 2 is attached to and horizontally associated with a side wall 14 of a furnace and fired upwardly (up-fired) with respect thereto. As discus...

Abstract

A burner assembly for and method of combusting fuel gas in a furnace is provided. The burner assembly includes a burner tile having a burner throat disposed therethrough. Combustion air is conducted through the burner throat into a combustion zone in the furnace. A pilot assembly is used to generate a pilot flame within the burner throat. Fuel gas is injected into an ignition zone located outside the burner throat and ignited therein. The pilot flame generated in the burner throat can be used to ignite the fuel gas in the ignition zone. The ignited fuel gas is admixed with combustion air in the combustion zone. The burner assembly can be operated without admixing a significant amount of fuel gas with combustion air in the burner throat, which can help control the formation of undesirable nitrogen oxides (NOX).

Description

BACKGROUND OF THE INVENTION[0001]Burner assemblies are used in many applications. For example, process burner assemblies are used in connection with industrial furnaces in petroleum refineries, chemical plants and similar facilities. The specific type and configuration of burner assemblies used will vary depending on the specific application, the type of furnace, the applicable emissions regulations and other factors known to those skilled in the art.[0002]A typical process burner includes a burner tile having a burner throat extending therethrough. The burner tile extends into the furnace. Combustion air is conducted through the burner throat to create a combustion zone in the furnace adjacent to the outlet of the burner throat. Fuel is injected into the burner throat, admixed with the combustion air and burned in the combustion zone.[0003]Many government authorities have adopted regulations relating to the amount of nitrogen oxides (commonly designated as “NOX” and primarily inclu...
