TURBINE HEAT RATE EVALUATION AND EFFICIENCY
- Turbine heat rate is defined as the heat input (Kcal) required to generate one unit of Electrical output (KWh). The trials are to establish heat rate (Kcal/kWh) and turbine efficiency under, as run conditions have to be carried out.
- The efficiency method given in this procedure is the enthalpy drop efficiency method. This method determines the ratio of actual enthalpy drop across turbine section to the isentropic enthalpy drop.
- This method provides a good measure for monitoring purposes. Each section of the turbine must be considered as a separated turbine.
- Each section should be tested and results are trended separately. While conducting the tests, it has to be ensured that, it is conducted over normal operating load range.
