Patent
John Zink Company | Date: 2017-07-05

The present disclosure includes air spinners for use in duct burners, and duct burners and duct burner kits including a plurality of air spinners. Air spinners may include a plurality of blades extending radially outward from a fuel path and configured to impart rotation to air flowing between the blades, where the air spinner is configured to be coupled to a fuel runner of a duct burner such that the air spinner encircles a fuel outlet of the fuel runner with the axis of the fuel path extending at a non-parallel angle from an axis of the fuel runner. Duct burners can comprise a plurality of air spinners coupled to a plurality of fuel runners. Duct burner kits can comprise a plurality of air spinners configured to be coupled (e.g., without welding) to a plurality of fuel runners.

An apparatus and method are provided for controlling the introduction of air into a burner. More particularly, the invention provides for a damper system that controls the introduction of air into a burner system by altering the size of a peripheral flow path for the introduction of air into the plenum of the burner.


Patent
John Zink Company | Date: 2012-01-18

A method of operating a flare assembly is provided. If it is determined that the injection of primary steam into the combustion zone is necessary to achieve smokeless operation, primary steam is injected through a steam injector assembly into the combustion zone. If it is determined that steam is not necessary, an alternative gas is discharged though the steam injector assembly into the combustion zone. In one embodiment, the alternative gas is heated. In another embodiment, if it is determined that steam is necessary, a maximum allowable flow rate of steam is calculated, and the flow rate of steam is modulated to achieve smokeless operation and avoid a flow rate of steam in excess of the maximum allowable flow rate of steam. A flare assembly is also provided.

Patent
John Zink Company | Date: 2012-06-07

An apparatus and method are provided for improved gas pilot burners, which are capable of simultaneous flame ignition and flame detection. More particularly, the invention provides for an apparatus and method capable of simultaneous high-energy ignition and flame ionization detection in a high-energy igniter that utilizes a spark rod located in a fuel channel.


Patent
John Zink Company | Date: 2015-08-26

A low NO_(X )burner in which the amount of air flow to the low NO_(X )(nitrous oxides) burner can be adjusted (e.g., based on determinations related to the TEG air flow to the low NO_(X )burner). A low NO_(X )burner capable of operating in a TEG mode that uses a mixture of fresh air and turbine exhaust gas (TEG) as an oxidizer, and also in a fresh air mode in which fresh air (but not TEG) is used as an oxidizer (e.g., and that may be configured to switch seamlessly between these modes). A method of operating a low NOx burner that that includes using TEG and fresh air as an oxidizer to burn fuel, in a TEG mode and, when conditions dictate, such as when the TEG flow has decreased to a pre-determined level (e.g., zero or close to zero), switching from the TEG mode to a fresh air mode.

The disclosure pertains to ignition systems and more particularly to spark igniters for burners and burner pilots. The spark igniter provided, is configured such that an electric field concentration between two electrodes increases while keeping output voltage unchanged.


Patent
John Zink Company | Date: 2012-03-28

A gas burner apparatus for discharging a mixture of fuel gas, air and flue gas into a furnace space of a furnace is provided. The burner tile includes at least one gas circulation port extending though the wall of the tile. The interior surface of the wall of the tile includes a Coanda surface. Fuel gas and/or flue gas conducted through the gas circulation port follows the path of the Coanda surface which allows more flue gas to be introduced into the stream. The exterior surface of the wall of the tile also includes a Coanda surface for facilitating the creation of a staged combustion zone. Also provided are improved burner tiles, improved gas tips and methods of burning a mixture of air, fuel gas and flue gas in a furnace space.
