Abstract: A computer method for creating optionality of price basis in a commodity contract includes establishing a smart contract for a transfer of a commodity using a distributed ledger and graphical user interface (GUI). The smart contract includes a variable price with a provision for a future determination of a price basis. The computer method includes receiving agreement on the smart contract between a seller and a counterparty, receiving a deposit on a total price from the counterparty, transferring at least a portion of the deposit to the seller, and transferring a token representing the smart contract to the counterparty. The computer method includes, at a future date, receiving a selection of the price basis for the smart contract from one of the counterparty or the seller, and notifying the other of the seller or the counterparty of the selected price basis and a resultant settlement price.

Abstract: A computer method and graphical user interface (GUI) for seller determination of commodity delivery location includes displaying, on an electronic display of a user device, a GUI including a commodity instance object, an ownership indicator, at least one preferred commodity delivery location object, a price indication field, a projected delivery date field, and a transaction wallet indicator. A commit object is displayed via the GUI. A user commitment is received via the commit objected into a server computer. The server computer causes transacting of a commit instance onto a distributed ledger carried by a plurality of non-transitory computer readable memories. An acknowledgment of the transaction commitment from the server is received, and a transaction status is displayed in the GUI.

Abstract: A real estate futures smart contract is established and offered via a GUI on an electronic display of a user device and carried by a distributed ledger. The futures contract may be offered for sale on an electronic exchange. The smart contract may carry a price indexed to a real estate futures price schedule.

Abstract: A method for a combustion system includes outputting fuel from an adjustable-position fuel nozzle onto a perforated flame holder, the fuel being directed for mixture with an oxidant en route to the perforated flame holder. A combustion reaction of the fuel and the oxidant is supported within the perforated flame holder. A position of the adjustable-position fuel nozzle may be changed relative to the flame holder. A first flow of fuel may be output when the adjustable position fuel nozzle is in an extended state, and a second flow of fuel may be output when the adjustable-position fuel nozzle is in a retracted state.

Abstract: Technologies are provided for a method and an adaptor for introducing electricity into a combustion chamber, for the purpose of electrical flame or combustion control. The adaptor may be placed between a conventional burner assembly and a conventional combustion chamber wall. The adaptor includes an aperture for admitting electricity into the combustion chamber.

Abstract: A fuel nozzle assembly includes one or more tapered fuel nozzles. Each tapered fuel nozzle includes an acute trailing edge or tip at a top portion of the fuel nozzle. One or more fuel orifices are arranged proximate the acute trailing edge or tip. A tapered fuel nozzle having a toroidal airfoil structure includes a fuel channel to distribute a fuel to the fuel orifice(s). The fuel nozzle assembly may be provided as part of a burner system, including a perforated flame holder, and associated method, in which the fuel nozzle assembly is oriented to direct fuel from the fuel orifices toward the perforated flame holder.

Abstract: A trapped vortex combustor includes a refractory combustor body defining a combustion volume aligned to receive an air and fuel mixture from an air and fuel source. The trapped vortex combustor includes a trapped vortex channel arranged circumferential to a portion of the combustion volume and/or arranged at or adjacent to a center of the combustion volume. The trapped vortex channel is configured to hold a trapped vortex combustion reaction to provide ignition to the air and fuel mixture. The trapped vortex combustor includes a center body supported near or within the combustion volume.

Abstract: A combustion system includes a perforated flame holder, an oxidant source, and an adjustable fuel nozzle. The oxidant source outputs oxidant. The adjustable fuel nozzle outputs fuel onto the perforated flame holder. The perforated flame holder supports a combustion reaction of the fuel and oxidant within the perforated flame holder. The position of the adjustable nozzle relative to the perforated flame holder can be adjusted to achieve selected characteristics of the combustion reaction within the perforated flame holder.

Abstract: A burner supporting primary and secondary combustion reactions may include a primary combustion reaction actuator configured to select a location of the secondary combustion reaction. A burner may include a perforated flame holder structure configured to support a secondary combustion reaction above a partial premixing region. The secondary flame support location may be selected as a function of a turndown parameter. Selection logic may be of arbitrary complexity.

Abstract: A combustion system supports a swirl-stabilized preheating flame with a preheating fuel and an oxidant. The combustion system preheats a perforated flame holder with the preheating flame. After the perforated flame holder has been preheated to the threshold temperature, the combustion system outputs a primary fuel. The perforated flame holder receives a mixture of the primary fuel and the oxidant supports a combustion reaction of the primary fuel and the oxidant.
