Large-flow liquid oxygen alcohol water vapor generator

The invention relates to a large-flow liquid oxygen alcohol water vapor generator which is composed of a head part and a body part, the working medium is liquid oxygen, alcohol and water, and ignition is carried out by an igniter which is arranged at the head part center specially; the liquid oxygen and the alcohol respectively enter a liquid oxygen chamber and an alcohol chamber through a liquidoxygen entry nozzle and an alcohol entry nozzle which are arranged at the outer bottom and the middle bottom, and enter a combustion chamber for combustion through a liquid-liquid coaxial centrifugalspray nozzle arrayed in a concentric circle mode, and initial high-temperature gas is generated; water enters the generator by dividing into four cross sections, water of the first three cross section enters a water collecting liquid chamber from the front end water inlet nozzle of each section of the body part, and enters the combustion chamber through a cooling ring with a tangential hole, thusa liquid film is formed, in
