METHOD OF PREVENTION OF CARBONIZATION OF OIL IN TURBINE SUPPORT OF GAS-TURBINE ENGINE WORKING TOGETHER WITH GAS- TRANSFER UNIT OR POWER PLANT FOR DRIVING ELECTRIC GENERATOR

摘要

FIELD: methods of prevention of carbonization of oil in members of gas-turbine engine supports in case of emergency shutdown of engine. SUBSTANCE: after emergency stop of engine supply of cold air is performed due to cranking of rotor. Air is fed through air exhaust pipes which evacuate supercharging air from seal of turbine oil chamber to supercharging cavity from external source. Air is fed at temperature below 100 C within period of time determined by mathematical expression given in description. Upon expiration of this period of time, temperature of turbine members which are in contact with oil in course of operation reduces to level excluding carbonization of oil, after which normal operation of engine is continued. EFFECT: enhanced efficiency. 3 dwg
