Abstract :
Steam power plants (PLTU) are a series of equipment whose work
processes utilize steam power to produce electricity. In a steam power plant
system (PLTU), which plays an important role is the boiler. The main purpose of
this system is to stabilize the pressure in the boiler using a pressure switch. This
final project was carried out for 4 months at the Bengkalis State Polytechnic
Electrical Engineering Department. The main method used is setting the
maximum pressure limit in the boiler. The results show that for a boiler pressure
of 1 bar, the blower on from the beginning of combustion is up to 67.29 seconds
and on again after the pressure drops to 0.5 bar. The pressure in the boiler is
always in intervals of 0.5 to 1 bar.
