  • Controlling TDS in the Boiler Water | Spirax Sarco

    As a boiler generates steam, any impurities which are in the boiler feedwater and which do not boil off with the steam will concentrate in the boiler water. As the dissolved solids become more and more concentrated, the steam bubbles tend to become more stable, failing to burst as they reach the water surface of the boiler.Learn More

    M alkalinity, or total alkalinity, is defined as the sum of carbonate, bicarbonate, and hydroxide. P alkalinity, or phenophtalein, is defined as one half of the carbonate alkalinity plus all of the hydroxide alkalinity. Carbonate and bicarbonate alkalinities can combine with calcium and magnesium hardness to form scale in boilerLearn More
