What should be the TDS of water used for boiler operation to prevent from spoilage of boiler vessels?

This depend on the type and pressure of the boiler:
Low-Pressure Boilers (0-300 psi): 500 – 3,500 ppm
Medium-Pressure Boilers (300-600 psi): 100 – 2,500 ppm
High-Pressure Boilers (Above 600 psi): 10 – 100 ppm

Good Question Muhammad Ashir , Appreciated

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.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.

The TDS should be kept as low as possible, ideally around 100 ppm, to prevent rust and corrosion in the boiler system…

To prevent spoilage of boiler vessels, controlling the Total Dissolved Solids (TDS) in boiler water is crucial. The TDS levels should be maintained within specific ranges to avoid issues such as scaling, corrosion, and carryover.

To prevent boiler vessel spoilage, boiler water, ideally less than 1.0 ppm for pressures up to 600 psig, and even lower for higher pressures.
