Title: Bleed air flow control system for axial flow compressor
Inventor: IWATANI JUNJI
IPC: F02C9/00
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To avoid wasteful air emission of compressed air so as to restrain wasteful work by measuring the temperature of a gas turbine and the pressure of a compressor at the time of start, and controlling to release bleed air to the air within the upper limit of the temperature of the gas turbine only when the pressure of the compressor is in the surge generation region. SOLUTION: In an axial flow compressor 10 in the course of starting speed-up operation, the pressure fluctuation of each bleed air stage is measured by pressure sensors 11-13 for the non-stationary state, and the measurement data is transferred to a computer 15 through an amplifier 14. The inlet and outlet temperature of a turbine 30 are measured by temperature sensors 20, 21 for all temperature measurement, and the measurement data is transferred to the computer 15 through an amplifier 22. In the case where the pressure amplitude of the axial compressor 10 is enlarged so that there is no possibility of a surge, close signals for valves 7-9 are sent to a valve motor control device 16, thereby controlling valve opening and closing motors 17-19 to close emission pipes 4-6 and conduct the operation of lowering load of the axial flow compressor 10.  That is, wasteful emission of compressed air is avoided.
