Abstract
A pair of pressure sensors having their openings in diametrically opposed positions are mounted in and substantially parallel to the flow stream in a turbine type power plant for obtaining a differential pressure signal indicative of an incipient surge condition. Logic circuitry selects a threshold value, whereupon the signal is utilized to provide an output signal for taking surge corrective action.
Claims7
Apparatus for detecting incipient surge in a gas turbine type power plant having an axial flow compressor comprising a pair of back-to-back disposed pitot tubes extending in the working medium of the gas turbine power plant, each of said pitot tubes oriented so that each of its openings is disposed substantially parallel to the flow of the working medium, means for sensing the pressure differential created by said pair of pitot tubes and means responsive to a predetermined threshold value of said pressure differential below which a signal is produced indicative of an incipient surge in said compressor.
