SISTEM KENDALI TEKANAN UDARA SEKUNDER PADA FORCED DRAFT FAN DI PLTU PAITON

Abstract

This research aims to assess the effectiveness of using Pressure Transmitters on the Force Draft Fan in a
Steam Power Plant. The evaluation is conducted through a series of tests to measure air pressure and analyze
the response of the Inlet damper position in regulating airflow. Data were collected through literature
studies, direct field observations, and interviews with relevant practitioners. The measurement results show
significant pressure variations. For a set point of 100 mmWG, the measured air pressure values range from
94.37 mmWG to 111.31 mmWG, and the percentage opening of the Inlet damper for FDF A & B varies
between 58.28% to 63.07%. There are some measurement errors that need to be further evaluated, with error
values ranging from -11.31 to 7,72 mmWG. Nevertheless, the system still operates within acceptable limits.
