TUBULAR-ANNULAR COMBUSTION CHAMBER OF GAS-TURBINE ENGINE Russian patent published in 2008 - IPC F23R3/14 

FIELD: mechanical engineering; gas-turbine engine combustion chambers.

SUBSTANCE: proposed tubular-annular combustion chamber of gas-turbine engine has annular space formed by casing which accommodates fire tubes with burning zone and mixing zone, fuel feed system and igniter. Annular space and front part of each fire tube are made hermetically sealed. Fuel feed system is made in form of nozzle to deliver ordinary water into casing space and nozzle provided with cavitator to deliver mixture of water solution of electrolyte and fuel into each fire tube. Igniter is made in form of arc electrodes with possibility of striking and blowing out of arc, dissociating, ionization, igniting and converting into plasma vapors of mixture passing through zone of arc burning said electrodes being installed in each fire tube. One of electrodes is made for displacement at striking of arc, and the other is made conical and provided with conical channel.

EFFECT: improved economy and ecological characteristics.
