Abstract: A method and system in which a waste gas or liquid product is combusted or otherwise used at a well site or other source location to drive a generator to produce electrical energy which is then stored in a portable storage device, such as rechargeable battery or an array of rechargeable batteries, which can subsequently be transported, for example, to a charging station for vehicles or other electrical devices or systems, or to a delivery location for downloading the portable stored electrical energy to a power supply grid.

Abstract: A plugging resistant, highly stable free jet burner and method which provide Ultra-Low NOx emissions for any fuel using angular ejection, large ejection ports, auxiliary burner tips, and wide tip-to-tip spacing, and which also permit the use of a high-hydrogen or 100% hydrogen fuel to reduce or substantially eliminate carbon dioxide emissions.

Abstract: A staged, lean pre-mix radiant wall burner having an internal staged fuel discharge tip and an internal flow diverter, and a method of using the radiant wall burner, which allow the combustion of a high hydrogen content fuel without the occurrence of flashbacks and which also provide reduced NOx emissions and allow a closer spacing of the burners when installed in a wall, floor, or ceiling of a fired heater in a multiple burner arrangement.

Abstract: A plugging resistant, highly stable free-jet burner and method which provide Ultra-Low NOx emissions using (a) large free-jet ejection ports, (b) a wide tip-to-tip spacing, and (c) auxiliary stabilization tips in the throat of the burner which are highly resistant to plugging and also produce very low levels of NOx emissions.

Abstract: A burner tip apparatus which is resistant to plugging, and a staged air method of operation which reduces the peak temperature of the flame of the burner tip to provide low levels of NOx and other emissions. The burner tip can be used as an auxiliary burner tip for stabilizing a main burner flame, or for other purposes.

Abstract: A burner apparatus and method which provide an increased amount of internal flue recirculation for reducing NOx emissions by ejecting a series of surrounding primary fuel streams and also ejecting on one or more subsequent series of surrounding fuel streams outside of the burner wall toward the burner combustion wherein each succeeding series of surrounding fuel streams must travel a greater distance to the combustion zone and each series of surrounding fuel streams must contact one or more radial impact structures provided on the exterior of the burner wall.

Abstract: A system and method in which (i) a flame scanner provides UV and/or IR wave period and amplitude information for a burner flame and (ii) a flame stabilization metering module determines whether the wave period and amplitude of the flame have reached warning and shutoff set points for the burner, thus indicating that the operation of the burner is unstable, or that a flame out event is likely, and, in which event, corrective actions are taken, or the burner is shut down, to restore stable operation and prevent a flame out from occurring.

Abstract: An assisted flare apparatus and method which increase the amount of air which is inducted into each of the flare combustion tip assemblies used in the apparatus by injecting the steam or other assist media used in each tip assembly into an inner conduit of the tip assembly which is configured such that at least a lower portion of the inner conduit is in the form of a venturi flow structure in which a straight venturi flow section is followed by a diverging venturi bell outlet section.

Abstract: A flow momentum enhancing device having an airfoil shape is used in a new or refurbished burner to increase the momentum of the burner combustion air stream and create a reduced pressure region which pulls inert products of combustion into the combustion process. The inert products of combustion mix with the burner air and/or fuel streams to lower the peak flame temperature of the burner and provide reduced NOx production.

Abstract: A burner apparatus for a fired-heater system and a method of burner operation wherein the burner fuel is ejected outside of the burner wall from a surrounding fuel discharge ring, or from a lateral elongate ejection bar in the case of a flat flame burner, to a combustion zone projecting from the forward end of burner wall. The burner apparatus and method reduce NOx production by a combination of enhanced internal flue gas recirculation and staged fuel operation.

Abstract: A burner apparatus for a fired heating system and a method of burner operation. The burner provides stable operation when burning gas fuels having heating values ranging from low to high and accommodates sudden wide changes in the Wobbe value of the fuel delivered to the burner. The burner apparatus includes a plurality of exterior fuel ejectors and has an exterior notch which extends around the burner wall for receiving and combusting a portion of the gas fuel. At least a portion of the hot combustion product gas produced in the exterior notch is delivered through channels formed in the burner wall to the combustion area at the forward end of the burner. As the Wobbe value of the gas fuel decreases, one or more outer series of addition ejectors can be automatically activated as needed to maintain the amount of heat output desired.

Abstract: A burner apparatus for a furnace system and a method of burner operation wherein a non-symmetrical positioning of one combustion fuel discharge tip or a grouping of fuel discharge tips within the burner wall produces side-by-side lean and fuel rich combustion stage zones and also produces internal flue gas recirculation.

Abstract: A burner apparatus for a furnace system and a method of burner operation. The burner has a series of fuel ejection structures which at least partially surround the burner wall for ejecting fuel into a combustion region projecting from the forward end of the burner wall. The ejection structures preferably eject fuel outside of the burner wall at alternating angles. Further, the burner apparatus preferably includes at least one additional series of fuel ejection structures which is spaced radially outward from the first series of ejection structures.
