Abstract
The operation of valves in steam turbines, especially main stop valves and control valves, requires oil as a working fluid, which flows in the hydraulic system and then flows to the control oil radiator to be cooled. There is a disturbance in the control oil radiator, namely, the performance in cooling the oil is not optimal, so it is assisted by a blower, caused by damage to the fins due to corrosion. The radiator output oil temperature reaches 59 °C while the recommended temperature based on the design standard is 45 °C. One way to solve the problem is to install a Plate type Heat Exchanger (HE) to replace the control oil radiator, so that the HE installation is appropriate, a simulation is carried out for the HE, to get the HE characteristics. The simulation resulted in an oil fluid channel velocity of 0.15m/s, a water fluid channel velocity of 0.2 m/s, an oil pressure drop of 34000 (N/m²), a water pressure drop of 23557 (N/m²) with a plate configuration of 30o and an outlet oil temperature of 45 °C.
