Usually this maximum temperature is 900 to 100O0F (480 to 54O0C). At higher heat transfer rates, and in high-pressure boilers, the problem is more severe: at temperatures in the 900 to 135O0F (482 to 7320C) range, carbon steel begins to deteriorate.Get a Quote
Controlling TDS in the Boiler Water | Spirax Sar
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.Get a Quote

Boiler Water Treatment Guidelines; Columbia Boiler
The pH should be maintained between a minimum of 10.5 and a maximum of 11.0 to prevent acidic corrosion of boiler tubes and plates, and to provide for the precipitation of scale forming salts before scale is deposited. Below a pH of 5.0 the water is acidic enough to dissolve the steel boiler plates.Get a Quote
