Liquid chlorine from the tonner is transferred
to the inner chamber of the vaporizer due to tonner pressure.
This chamber is immersed in a water bath, which is heated
by 3 Nos. heaters. The water to the water bath is supplied
via pipe which is controlled by an on-line solenoid Valve,
which opens once the water level falls below the preset level
and closes once the water reaches the higher preset level.
The temperature of the water is controlled by a thermostat,
which switches on or off depending on the temperature reached,
by the water bath. Cathodic protection is provided where,
DC current is passed through sacrificing carbon anodes to
protect, the Heat Exchanger and Hot water tank surface exposed
to water from Galvanic Corrosion.
