摘要： PURPOSE: To enhance the waterproof effect of a spherical portion by arranging a tubular member for delivering relatively high temperature air in the central portion of a rotary front spherical portion of a gas turbine engine, providing a double structure to the spherical portion and communicating the space therein with the tubular member. CONSTITUTION: In a gas turbine 1 comprising low and high pressure compressors 2, 3, a combustion device 4, a high pressure compressor 5 and a low pressure compressor 6, a front spherical portion assembly 10 is arranged at the end portion upstream thereof to form the radial inner wall of an air inlet. A tubular member 14 is arranged in the center of the assembly 10. The rear end thereof is connected to the front end of a hollow drive shaft 7. The assembly 10 is formed by an inner skin 16 and an outer skin 17. A space 20 communicating with the tubular member 14 is formed between the two skins 16, 17. The relatively high temperature air delivered through the tubular member 14 is blown to the central portion of the outer skin 17 and discharged through the space 20 and a hole 22, so that the surface of the assembly 10 is provided with a waterproof property.

摘要： PURPOSE:To make suction air temperature rise and dissolve the freezing of moisture in the atmosphere as well as to prevent any damage to a compressor due to the freezing from occurring, by leading steam by bleed air out of a steam turbine into a compressor inlet of a gas turbine, and mixing this steam with the atmosphere to be sucked in to the compressor. CONSTITUTION:A compound power plate is provided with a gas turbine 1, a generator 2, a steam turbine 3 and a waste head recovery steam generator 4. And, the gas turbine 1 is provided with a compressor 5, a combustor 6 or the like, and the atmosphere 8 is sucked into the compressor 5 from an inlet casting 9. In addition, in this inlet casing 9, there is provided with an inlet guide vane 10 which is opened or closed when a temperature of exhaust gas is regulated. In this case, the specified amount of steam 23 is sprayed to the inside of the inlet casting 9 from a nozzle 13 on the basis of a detection signal out of the temperature sensor 14 installed in the downstream of the guide vane 10. With this constitution, when the guide vane 10 is throttled, such fear of moisture in the atmosphere 8 being frozen and damaging a blade 11 of the compressor 5 is obrated.
