Controlling TDS in the Boiler Water | Spirax Sarco

Conventional shell boilers are normally operated with the TDS in the range of 2 000 ppm for very small boilers, and up to 3 500 ppm for larger boilers, provided the: Boiler is operating near to its design pressure. Steam load conditions are not too severe. Other boiler water conditions are correctly controlled.
