Chlorine Vaporizer
Vaporizers are recommended for higher continuous chlorine gas feed rates, when it is not practical to use manifolds for the gas lines of the required number of containers. By withdrawing the chlorine as a liquid and using vaporizer, flow rates can be greatly increased.  
Electrically Heated Vaporizer:
Liquid chlorine from the pressurised tonner flows to the inner chamber of the vaporizer. 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 a solenoid operated 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 upon the temperature of the water bath. To protect the Heat Exchanger and Hot water tank surface exposed to water, from Galvanic Corrosion, Cathodic protection is provided by means of sacrificial carbon anodes.  
Steam Heated Vaporizer:
Chlorine Vaporizer can also be powered by steam. Steam is abundantly available in Paper & Pulp Mills, where steam is used to evaporate liquid Chlorine to form gas Chlorine. A temperature controller opens or closes a steam valve, thus maintaining a constant temperature in the steam chamber.
