PURPOSE:To measure the temperature of exhaust gas with high precision at low cost by calculating heating values from data on temperatures and flow rates of exhaustion and suction, and finding the temperature of exhaust gas at the exit of a flue from the sum of the heating values. CONSTITUTION:Respective measurement data of gas turbine exhaustion temperature and flow rate detectors 1 and 2, package exhaustion temperature and flow rate detectors 3 and 4, generator exhaustion temperature and flow rate detectors 5 and 6, and cooling suction temperature and flow rate detectors 7 and 7 are supplied to the CPU 11 of a measuring instrument body 9. The CPU 11 calculates the heating values of exhaustion and suction from those data according to a program which is inputted previously, and calculates the temperature of gas at the flue exit from the sum of the heating values to display it on a display device 13. Consequently, the exhaustion temperature at the flue exit is calculated with high precision and numbers of thermometers need not be installed, so that a measurement is taken at low cost. |
