METHOD FOR PREVENTING OIL CARBONIZATION IN TURBINE SUPPORT OF GAS-TURBINE ENGINE INCORPORATED IN GAS-TRANSFER PLANT OR POWER UNIT IN CASE OF THEIR EMERGENCY (ACCIDENTAL) STOPPING

摘要

FIELD: power-plant mechanical engineering; turbine supports of gas-turbine engines used for driving gas-transfer plants or power units. SUBSTANCE: in case of emergency stopping of gas-turbine engine, cooling air having temperature t≅ 100C is supplied within time τ through pipes dumping air supercharging seals of turbine support oil space to pre-oil charging space or through breather pipes, to oil space from external energy source; upon expiration of this time, temperature of support parts drops to point at which oil carbonization is impossible. EFFECT: improved reliability of turbine supports of gas-turbine engines incorporated in gas-transfer plants or power units.
