Answer Posted / naik muhammad
Most boilers of medium to high pressure today use a “3-
element” boiler control strategy. The term “3-element
control” refers to the number of process variables (PVs)
that are measured to effect control of the boiler feedwater
control valve. These measured PVs are:
▪ liquid level in the boiler drum,
▪ flow of feedwater to the boiler drum, and
▪ flow of steam leaving the boiler drum.
