TURBINE UNIT OF GAS-TURBINE POWER PLANT

摘要

mechanical engineering; gas-turbine power plants. SUBSTANCE: turbine unit has container, gas-turbine engine enclosed in casing, and draft facility communicating with casing interior. Container inner space communicates with draft facility through air duct that has choke and communicates with casing interior and with cooling air source. Container does not incorporate separate cooling system but turbine unit is designed so that excessive temperature rise within container during both idle running and full-load operation of gas-turbine engine is made impossible. EFFECT: enhanced operating reliability of turbine unit. 1 dwg
