Developments in Data Acquisition and Processing Using an Advanced Combustion Research Facility,

Abstract

A new combustion rig is described which is designed to acquire rapid and detailed information on the combustion processes occurring within a sector of large annular gas turbine combustors operating over a range of inlet pressures and temperatures representative of engine conditions. Gas samples are extracted using a probe positioned within the volume under examination and transferred to a system designed to perform analyses with a point-to-point cycle time of less than 30 seconds. A computer is used to control and synchronise the probe positioning and gas analysis function and to present co-ordinated results to rig controllers. The system is capable of automatic traversing within a prescribed volume or of control by a dummy traverse gear which permits tracing of air and fuel flows. This paper outlines the main features of the rig, together with the types of instrumentation, the methods and range of operation used and anticipated.
