ABSTRACT / SAŽETAK:
In 2024, a new thermal power plant within the JSC Elektroprivreda Srbije, the TPP Kostolac Unit B3 with 350 MW and supercritical parameters, was put into operation. The equipment supplier guaranteed the turbo generator gross specific heat consumption, the efficiency of the live and reheat steam pipeline, main steam flow rate, and the pressure and temperature of steam at the boiler outlet. Faculty of Mechanical Engineering, Belgrade – Laboratory of Thermal Turbomachinery performed guarantee testing during October 2024. The contract defined that the testing be carried out according to the ASME PTC 6 standard. The standard requires the use of a calibrated nozzle for flow measurement, with measurement uncertainty not being considered when comparing measured values with guaranteed values. The paper presents specific requirements regarding the applied test standard, measurement techniques, as well as the calculation of measurement uncertainty of test results.
