摘要： A flat spray fuel nozzle comprising a generally spherical tip with an elongated fuel discharge slot extending from a spherical chamber. A fuel splitter is adjustably positioned in the chamber, by means of a sleeve-like shim, to divert and reunite fuel at the slot to increase turbulence. An air shroud surrounds the exterior of the tip and has a discharge slot in line with the slot in the tip. A splitter element is positioned in the shroud so that air passing through the shroud is divided into separate streams which impinge on either side of the liquid film adjacent the fuel slot to further increase atomization of the fuel.

摘要： Implementations of a combustor assembly yield low emissions, require low power, are suitable for alternate liquid fuels, including highly viscous fuels, and are scalable for various heat release rates. The combustor assembly includes a fuel injector and a swirler. The fuel injector may include a choke portion and a spacer. The choke portion is disposed just upstream of an outlet of a liquid fuel conduit and prevents atomizing gas from interrupting continuous flow of the liquid fuel through the liquid fuel conduit. The spacer is disposed downstream of the outlet to precisely control the gap and thus, bifurcation of atomizing gas flow, between the outlet of liquid fuel conduit and an inlet of an orifice plate. The swirler is disposed radially outwardly and adjacent the fuel injector and includes a plurality of angled vanes.

摘要： A method for oxy-fuel combustion, the method comprising the steps of: introducing a liquid fuel into an emulsion chamber through a liquid fuel conduit having an effective diameter, the emulsion chamber having a length that is 2 times or less than 2 times of said effective diameter of said liquid fuel conduit; introducing an atomizing gas into the emulsion chamber through at least one atomizing gas conduit; mixing the liquid fuel and the atomizing gas in said emulsion chamber to create an emulsion mixture that has a mean residence time in said emulsion chamber of from 500 to 800 μs, the emulsion mixture having an emulsion mixture velocity less than or equal to 12 m/s; and discharging said emulsion mixture through a generally rectangular-shaped orifice into an oxygen-enriched oxidizer stream. A nozzle and burner for oxy-fuel combustion are also disclosed.

摘要： A liquid fuel burner head features an axially movable primary air assembly carrying a centrally disposed nozzle spraying fuel radially of the burner head. Primary air ports surround the nozzle and include means for progressively increasing swirl of the primary air as radial distance from the nozzle increases and for adjusting the location of flame origin. Metering of secondary air and adjustment of its direction of swirl are both accomplished rearward of the secondary air outlet, the primary air assembly moving rearwardly to increase the secondary air as firing rate rises. A simple metal, frusto-conical flame holder is secured to and spaced forwardly of the burner head.
