Study of an Experiment System and Flow Measurement of Group Nozzles in A Heavy-Duty Gas Turbine

Study of experiment system and experimental investigation results of the group nozzles in a heavy-duty gas turbine are expatiated. In order to measure gas flows of every flow branch in the group nozzles, flow meter of type SH-1 is specifically developed, The measure system, control system, data display system, data acquisition analysis system subtly combine, the SH-1 gas flow test equipment and these measured flows data are precise, stable, good reproducibility, the errors of the measuring are less 0.5%. Using SH-1 flow meter, gas flows of III,IV,V branches are precisely measured, the combustion testing of the group nozzles in the flame tube is made, its performance is satisfied with the design requirements, these demonstrate: the testing results by using SH-1 flowmeter are reliable, stable.
