THE THREE ELEMENT IN BOILER IS
(1)STEAM FLOW
(2)FEEDWATER FLOW

we use multiloop controller with cascade facility to
control drume level, in this level is use as a primary
setpoint SP, the out put of primary loop is being setpoint
of secondary loop and this is water flow, so that if our
primery setpont is maintain automaticaly steam pressure
maintain. so we use three element in boiler drume level.
