METHOD OF FUEL BURNING Russian patent published in 2010 - IPC F23D5/06 F23C99/00 

FIELD: power engineering.

SUBSTANCE: method of fuel burning consists in separate jet supply of fuel and oxidiser by forming fuel film distribution and combustion. Notably, jets of fuel and oxidiser are supplied to separate, inclined to each other and distanced plates. The jets impact surface of the plates so, that film spreads over after the impact of fuel and oxidiser against the plates and thin films descent off surface of the plates into distance between them. The fuel film is directed towards the oxidizer film and they merge in the distance between the plates. Merging films are ignited creating burning vortexes beyond the film bounds. Burning fuel in vortexes heats back sides of impact places and due to transfer of heat through walls of the plates it warms films of fuel and oxidizer before their encounter. Also rate of fuel and oxidiser jet spreading over is maintained within 6-80 m/sec and angle of encounter of jets with the plate is held within 92-120 degrees in the direction of film descent. Distance between the outlet section of the nozzle and the point of encounter of jets and the plate is 4-25 of diametre of the nozzle of the output cross section; while distance between axial lines of jets at point of encounter with surface of the plates and the edge of the plate is 2-15 of nozzle diametre in outlet section. This distance increases from outlet section of the nozzle to the point of encounter with the plate.

EFFECT: increased efficiency of fuel burning, raised temperature in jet, decreased length of jet, improved heat transfer from jet to heated material, upgraded efficiency ratio of heat facility, and decreased fuel consumption for material heating.
