Abstract: An injection nozzle utilizing nitrous oxide to aid in the introduction and atomization of fuel into a combustion chamber. The present invention comprises a Y shaped nozzle having a pair of input ports and a single output port. One input port is utilized to introduce nitrous oxide into a hollow sleeve of the nozzle and ultimately exiting at the output port. The second input port introduces fuel to the nozzle. A fuel line coupled to the second input port extends the length of the hollow nozzle, terminating at the output port extends the length of the hollow nozzle, terminating at the output port. The nitrous oxide is introduced at high pressure, approximately 500-1000 PSI. The fuel is introduced at approximately 3-12 PSI. As the nitrous oxide exits past the end of the fuel line, it creates a vacuum which aids in drawing the fuel from the line.

Abstract: A burner and method is disclosed in which a first oxidizing gas containing a high oxygen concentration is injected as a stream into the central zone of combustion tunnel, and part of the fuel is injected into said central pyrolysis zone to mix with said first oxidizing gas to create a highly luminous, high temperature flame core containing microparticles of carbon of the proper size for maximum luminosity and high temperature, and a relatively small amount of hydrocarbon radicals. In addition, the remaining part of the fuel is injected in a plurality of streams about said flame core to mix with a second oxidizing gas containing a lower oxygen concentration than the first oxidizing gas and injecting said second oxidizing mixture about said flame core and said remaining fuel flow to mix with said remaining fuel flow. This creates a plurality of fuel lean flames which are directed toward said luminous flame core to form a final flame pattern having high temperature, high luminosity and low NO.sub.x content.

Abstract: A nozzle that consists of a pipe (4) with the end that extends into the treatment space surrounded by a hood (6) is employed to inject solids into a reaction space, a fluidized-bed combustion chamber for example, pneumatically. There are outlet bores (12) in the wall of the pipe (4) and below the lower edge of the hood (6). Inside the pipe (4) is an inner pipe (13) that is connected tight to pipe (14) above the outlet bores (12) and that creates in conjunction with the pipe (4) a space (14) for air to flow through. The air flowing through this intermediate space (14) and emerging from the outlet bores (12) ensures transverse intermixture of the solids inside the reaction space.

Abstract: The present invention relates to a combustion method for reducing the emission of nitrogen oxides. More particularly, the quick mixing of the air and fuel in the early stage of combustion is suppressed by setting the direction of fuel injection at an angle to the direction of the air stream axis and a position of a burner, in a preferable range resulting in the consequent effective use of a combustion exhaust gas, thereby minimizing the emission of nitrogen oxides to a great extent.

Abstract: A spray head suitable for spraying thickened colliery tailings onto a fluidized combustion bed includes a central aperture for the egress of gas directed towards and surrounded by an annular orifice for the discharge of the material to be sprayed. As the material issues forth in use from the orifice a gas flow from the central aperture impinges upon it to generate the spray the characteristics of which may be varied by altering the size and/or location of the central aperture. An annular aperture located around the orifice provides for the discharge of a gas in the form of a curtain which protects the head from excessive heat which might otherwise cause agglomeration of material on the head.
