DIFFUSION INJECTOR-TYPE BURNER (VARIANTS) Russian patent published in 2008 - IPC F23D14/24 

FIELD: the invention refers to the field of incineration of fuel particularly to the construction of a fuel-feeding arrangement.

SUBSTANCE: there are two proposed variants of fulfillment of diffusion injector type burners consisting of a body from one side rigidly connected with a nozzle fulfilled in the shape of a diffuser and from the other side- also rigidly- with a control mechanism having a branch pipe for feeding gas. Inside the body there is built-in from the side of the nozzle a throttle fulfilled in the shape of a truncated cone, with its large foundation directed into the side of gas movement, moreover the correlation of the diameter of the nozzle to the large diameter of the throttle does not prevail 1,4. On the throttle there are blades rigidly fixed in such a way that the projections of the lateral walls of the blades overlap free section of the burner. At that the throttle is connected with the control mechanism with the aid of a rod connected with the control mechanism movably. According to the first variant the rod is fulfilled hollow and the throttle is fulfilled with a hollow axis channel, at that the throttle and the rod are connected between themselves hermetically and a regulated shutter is installed in the rod from the side of the control mechanism. According to the second variant the rod is fulfilled hollow. The throttle is fulfilled with a hollow axis channel, at that the throttle and the rod are connected between themselves hermetically. In the channel formed with the cavity of the rod and the axis channel of the throttle there is the second burner for liquid fuel and (or) a tube each of which has one end on the edge of the throttle and with the other end the burner for liquid fuel is connected with an alternative kind of liquid fuel, and the tube is connected with liquid combustible wastes. Besides a regulated shutter fulfilled with possibility of overlapping the free section of the hollow rod and for possibility for passing through it of the second burner for liquid fuel and the tube is installed in the rod from the side of the control mechanism. The invention is directed on increase of intensification of incineration of fuel and besides on providing incineration of several kinds of fuel including utilization of liquid combustible gases.

EFFECT: allows reduce consumption of materials in the process due to replacement of part of the main fuel on more cheap residues of production.
