High Pressure HRSG and Co-Generation Water-Steam

2015-9-29 · Boiler Water Treatment . In the 1930s as steam generator technology evolved and high-pressure units grew in numbers, tri-sodium phosphate (TSP, Na 3 PO 4) became the common chemical for boiler water treatment as it generates alkalinity (caustic, NaOH) to protect against corrosion. Also, phosphate reacts with hardness compounds to reduce the

Why is steam condensate corrosive? – Akvante

Make-up water and subsequently boiler feedwater contain alkalinity (here we are referring to low-medium pressure boilers that use softened water). Alkalinity is the acid neutralizing ability of the water and it mainly consists of carbonate (CO 3 2-) and bicarbonate (HCO 3 –) ions.
