METHOD OF AND DEVICE FOR PRODUCTION OF WORKING MEDIUM ON THREE-COMPONENT FUEL Russian patent published in 1998 - IPC

FIELD: production of working medium. SUBSTANCE: proposed method of production of working medium on three-component fuel is designed for production of products of gas generation with excess fuel at combustion of oxygen-kerosene-hydrogen three-component fuel without solid carbon particles and for provision of complete serviceability of gas owing to organization of fuel combustion process with different temperature zones. Method comes to successive delivery of kerosene and hydrogen. Moreover, possibility of fixation of free carbon is used. Free carbon can form during working reactions of oxygen and kerosene with hydrogen with forming of gaseous method ((C+2H₂=CH₄)) by adding 5 - 15% of hydrogen in oxygen and kerosene burning zone. To obtain gas generation products at the second stage of operation of gas generator kerosene is replaced by "warm" hydrogen. Method is realized in device consisting of mixing head 1, outer bottom unit 2, header unit 3, chamber 4, adapter 5, spherical screen 6 and kerosene header unit 7. Mixing head is made three-space, with separate delivery of each component. Head has also three-component nozzles of antechamber type and centered oxygen nozzle. Oxygen nozzle is provided with holes arranged in series and connecting kerosene space with nozzle chamber. Jet channels made on end face around nozzle chamber connect balancing hydrogen space with gas generator chamber. Holes made on wall in outlet part of nozzle chamber connect hydrogen space with nozzle chamber. To provide guaranteed high temperature burning zones and serviceability of gas different design devices are used for delivering balancing kerosene and hydrogen. EFFECT: provision of complete serviceability of gas. 13 cl, 11 dwg
