INDIRECT HEATING SYSTEM

Indirect heating system is provided for phosphate tank. It mainly consists of PHE, 3- way pneumatic valve and warm water tank. Water in warm water tank is heated using direct fired heating system. Heated water then circulated to PHE using 3-way pneumatic valve. Phosphate chemical is also circulated to PHE and heated chemical returns to chemical tank. Chemical gets heated due to heat transfer from warm water in PHE. Once desired temperature reached, 3-way pneumatic valve cut off the flow of warm water to PHE.
