Process Description: The boiler drum made up SS304 contains water which is electrically heated with a PWM
controller and generates steam at 4 bar and 144 ºC. The water for heating is pumped from a boiler feed water tank using
a positive displacement pump. The steam generated flows towards the heat exchanger through an equal percentage
globe valve which controls the steam flow.
The heat exchanger being of tubular counter flow type, water to be heated is pumped from a cold water tank from the
other end using a centrifugal pump. The condensate formed in the heat exchanger during heat transfer is collected in a
separate condensate tank. The hot water is collected in hot water tank which also be either mixed in the cold water tank
or can be added partially/fully to the feed to the boiler to change the feed water temperature.
