Abstract :
Every Steam Power Plant needs power and energy to operate their electrical
devices. In PLTU Banten 3 Lontar there are a lot of electrical devices that consumed
power and energy in large amounts, for example boiler furnace?s fans. One of them is FD
Fan, where FD Fan itself has the function to blow outside air to the furnace chamber.
FD Fan is moved by induction motors that consumed large amounts of energy which is
500 kilowatts. From this matter, the writer wants to apply Variable Speed Drive to
decrease the energy consumption of FD Fan with an examination which open the damper
of FD Fan into 100% open. Where Damper has the function to control the amount of air
that flows through the FD Fan into the furnace chamber. From the examination and data
calculation the writer did in this study, the energy consumption is 69% decreased. The
writer also did a calculation of payback period with the estimated investment cost and
calculate the profit of energy consumption cost per month. The result of the payback
period calculation is, the investment cost will return in approximately 5 months.
