STARTING FUEL SYSTEM OF SHIP GAS TURBINE ENGINES Russian patent published in 2003 - IPC

FIELD: shipbuilding. SUBSTANCE: proposed starting fuel system of ship gas turbine engine consists of engine fuel filter, starting fuel shutoff device, igniter body and nozzle and pipeline connecting pipeline behind engine fuel filter with igniter. Starting fuel shutoff device is made in form of valve. Starting fuel system incorporates restrictor. Igniter id provided with filter and spark plug. Union installed before igniter filter is connected by pipeline with check valve through shutoff valve with ship air and system. Invention improved reliability of operation of starting fuel system owing to higher quality of prestarting preparation of engine systems and decreases amount of non-combusted fuel particles into atmosphere through engine passage part owing to reduction of number of starting failures. EFFECT: improved reliability of starting. 1 dwg
