| A spray nozzle is provided with upper and lower channels and from respective surfaces, the two channels form a cross shape, and become a fuel spray hole by communication of an intersecting part. A guide member is provided, in contact with the upstream-side channel, in a position overlapped with the intersecting part with respect to the spray direction of the spray nozzle. Spray fluid is branched with the guide member from the fuel fluid duct connected to the spray nozzle, passes through the upstream-side channel, to the intersecting part, and is sprayed. The spray fluid forms opposed flows toward the intersecting part in the upstream-side channel to collide with each other at an obtuse angle of 90° or greater, then is sprayed from the intersecting part, to form a thin fan-shaped liquid film. The liquid film is divided by a shearing force from the peripheral gas, atomized into spray particles. | ||||||

| 48 | Glycerin burning system | US12800661 | 2010-05-20 | US20100233640A1 | 2010-09-16 | Radek Masin |
| A glycerin burning system having a specialized atomizing burner capable of combusting a continuous feed of crude or pure glycerin. The burner preferably includes an impingement nozzle. The nozzle has an internal distributor which mixes two fluid feed streams (glycerin and air) and expels the fluid through an orifice. The distributor has channels which cause the air to swirl before mixing with the glycerin. An impingement pin is provided outside the orifice. The rapidly ejected glycerin/air mixture strikes a target surface on the impingement pin which transforms the mixture into a fine mist having a reduced velocity. The nozzle is located on the central axis of a turbulator which surrounds the atomized spray with rapidly revolving air. An outlet choke is provided on the combustion chamber to limit the speed of the flow so that steady combustion is maintained. | ||||||

| A glycerin burning system having a specialized atomizing burner capable of combusting a continuous feed of crude or pure glycerin. The burner includes a two-fluid mixing nozzle. The nozzle has an internal distributor which mixes two fluid feed streams as the fluids are expelled through an orifice. The distributor has channels which cause the air to swirl before mixing with the glycerin. An impingement pin is provided outside the orifice to diffuse the mixture and reduce combustion air speed. To improve performance, the burner's air feed line is subjected to combustion chamber to preheat the air passing through the feed line before the air is mixed with the glycerin. | ||||||

| A fuel/oxidizer pre-mixing combustion chamber for a turbojet engine is disclosed in which the pre-mixing device is incorporated into the upstream end wall structure of the combustion chamber. The upstream end portion of the combustion chamber, which is in communication with the oxidizer, has a plurality of generally radially extending, "V"-shaped members oriented such that the vertex of the "V" shape faces in an upstream direction. These members extend generally radially between the inner and outer walls which define the boundaries of the combustion chamber. The members define upstream edges and downstream edges which are axially the upstream edges. Fuel injectors extend radially inwardly between these members and are axially positioned between the locations of the upstream and downstream edges so as to spray fuel onto the adjacent sides of each of the members. The downstream edges of the members are circumferentially spaced apart so as to define a passage which is in communication with the oxidizer source and the combustion chamber. | ||||||
