Answer Posted / pramod d.gaur
Three element means to control three parametes,i.e.
feedwater flow in to the drum, steam flow and level
control of drum,now in a three element, the set point of
level control track the ratio of steam flow to the
feedwater flow,i.e, as much as amount of steam flow flow
out of drum or in other word steam consume by process
equall amount of feedwater flow in to the drum.In such
cases there is very least chances that water from the drum
get carried away with steam in to the turbine when there is
load fluctuation
