Alkalinity Builders | Boiler Water Treatment Chemica
CALCULATE THE LIMITING CONCENTRATION FACTOR BASED ON TDS AND ALKALINITY. In a shell steam boiler operating up to 30 bar (435 psi) we are limited by BS2486 to a maximum TDS of 3000mg/L and a maximum Alkalinity (M) of 1200mg/L. Both of these are usually present in the softened make-up water and both will concentrate up in the boiler.Get a Quote
QUIZ: Boiler Water Treatment Chemical Guidelines — Part
Boiler Water Treatment Chemical Guidelines—Part Il continued Because of the associated corrosion problems, chelants are not the preferred treatment choice.
