SYSTEM FOR FUEL SUPPLY FOR GAS-TURBINE PLANT

摘要

FIELD: gas-turbine engine engineering. SUBSTANCE: gas is supplied to passive nozzle 6 of additional ejector 7 from pipe line 9 under a low pressure. Inside the ejector the gas is mixed with water vapor that is supplied to active nozzle 11 from high-pressure steam pipe line 12 and its pressure rises at the outlet. The steam-gas mixture enters additional condenser cooler 6 where it is separated into gas and water components. The water component is supplied to the inlet of steam boiler 17 through outlet 19, whereas the gas component enters the inlet of ejector 5 through outlet 18. Being mixed inside the ejector with water steam supplied to active nozzle 10 from high-pressure steam pipe line 12 the gas rises its pressure at the outlet. The steam-gas mixture enters condenser-cooler 4 where it is separated into the gas and water components. The water component enters water batcher 15 through outlet 14. A portion of water flows to the nozzles 16 for water supply and the other portion of water is supplied to the inlet of steam boiler 17. The gas enter controller 3 of fuel supply through outlet 13 and further fuel nozzles 1 of combustion chamber 2. Controller 3 of fuel supply and water batcher 15 maintain a required condition in combustion chamber 2. EFFECT: enhanced reliability.
