  • Patent number: 11187622
    Abstract: An apparatus, system, and process for testing a gas turbine engine or other test object under a cold condition, such as a compressor of a gas turbine engine, a combustor of a gas turbine engine, or an afterburner of an aero gas turbine engine, using compressed air stored in an underground storage reservoir of a CAES system along with an air turbine or an air injector. High-pressure, but low-volume, compressed air from a CAES system can be converted into a low-pressure, but high-volume, flow of compressed air using an air injector to supply enough compressed air to test a combustor or an afterburner. High pressure compressed air from the CAES system can be used to drive an air turbine that then drives a compressor for testing.

  • Patent number: 11181432
    Abstract: A method for diagnosing a differential pressure line of a differential pressure measurement arrangement includes capturing a first set number of differential pressure values, which represent a difference between a first media pressure and a second media pressure within a process, and checking whether the differential pressure measurement arrangement and/or the process are in a state that allows a diagnosis of the differential pressure line. Where it is determined that the differential pressure measurement arrangement and/or the process are not in a state that allows a diagnosis of the differential pressure line, the differential pressure values are captured anew such that the previously captured differential pressure values are deleted or overwritten. Otherwise, a diagnostic function to determine whether a differential pressure line is blocked is carried out.
