Pengaruh Variasi Pressure Dan Temperature Terhadap Heat Rate Turbine Unit 8 Di Riau Prima Energi

---

ABSTRACT
The consumer's need for electrical power varies from time to time which causes
the mechanical load borne by the turbine to vary. This change in mechanical load
causes a direct change to the work performed by the turbine shaft. Each turbine
has a different efficiency value, depending on operational conditions. One of the
operational conditions that influence is the steam pressure and temperature
parameters that enter the turbine. These parameters will affect the value of the
turbine heat rate and efficiency values. This final project aims to determine the
heat rate in the turbine unit 8 based on the parameters of varying steam pressure
and temperature. For pressure variations, namely 70, 80 - 85 bar abs and
temperature variations of 475 - 480ºC. With this variation it can be seen the limits
that can still be borne by the turbine with the resulting low heat rate. The method
used to calculate the efficiency value and heat rate value is the actual data
collection on the turbine unit 8 back pressure obtained from the DCS (Distributed
Control System) and the actual data processing for calculations. Based on the
calculations that have been done, the higher the pressure, the lower the heat rate
value obtained. In normal conditions, the actual heat rate value is 896.42 kcal /
kWhr and the actual efficiency value is 101.49%. With this condition indicates
that the turbine is very efficient and has a good condition to operate. While the
abnormal condition obtained an actual heat rate of 1012.50 kcal / kWhr with an
efficiency value of 89.85%. With abnormal conditions this turbine is inefficient
because the heat rate obtained exceeds the design value and the efficiency value
does not reach the design value.
