A two phase fuel oil atomizer utilizing a secondary media such as high pressure steam or air to assist in the atomization of heavy fuel oil, while reducing NOx and other polluting emissions. The fuel oil atomizer comprises a mixing plate and a sprayer plate which are configured to discharge atomized fuel oil at varying spray angles in order to provide staging of the atomized fuel as it exits the sprayer plate with the surrounding combustion chamber air to provide a fuel/air ratio that is appropriately rich and lean in order to allow lower flame temperatures. NOx generation is accordingly reduced at the lower flame temperatures. With atomized fuel droplet size small enough to enable rapid fuel evaporation and complete combustion, low CO, opacity and particulate generation are achieved with minimum excess oxygen.

An atomizer spray plate is provided for discharging fuel oil. The spray plate has a cylindrical rear portion and a conical front portion. A frusto-conical whirl chamber extends from the rear portion to the front portion with a decreasing radius. The rear portion includes a number of whirl slots extending radially inward from an outboard region of the rear portion to the whirl chamber to provide the fuel oil with rotational energy. A discharge slot is provided in the front portion of the spray plate for receiving fuel oil from the whirl chamber with rotational energy. The discharge slot includes a cylindrical through-hole with a diameter d, and at least three lobes (slots) equally spaced about the through-hole and oriented in a radial direction, each lobe having a semi-circular cross-section with radius r and extending approximately perpendicular to a central longitudinal axis of the through-hole.

Pulverized coal and air flowing-in a coal nozzle are distributed for combustion with low NOX generation by a concentric central duct with long exterior spiraling vanes which extend upstream and attach to a support pipe extending further upstream in the nozzle. The space from the downstream end of the support pipe to the upstream end of the central duct, and the cross section of the pipe relative to the cross section of the central duct regulate the entry of coal and air into the central duct from which the flow emerges with reduced velocity as a central stream stabilizing the flame. The central duct also has an exterior short vane attached to each long vane to separate the pulverized fuel and air outerflow into fuel-enriched swirling streams and fuel-depleted recirculation zones.

Apparatus is disclosed for minimizing the infrared radiation emitted at the aft end of a bypass fan type turbine engine. Minimization is accomplished by ducting cool air from the secondary bypass airstream through an annulus to form a sheath of cooler air around the gas stream as it is discharged from the engine tailpipe. The sheath of air educted along the inside surface of the engine tailpipe minimizes infrared radiation in two ways. First it reduces the operating temperature of the tailpipe thus keeping radiation therefrom to a low level. Second, the cool outside air becomes entrained in the hot gas stream discharged from the turbine. This results in a reduction of the effective temperature of the gas plume and suppresses infrared radiation therefrom.
