  • Water for the Boiler - Spirax Sarco | First for Steam …

    A boiler' job is to generate steam, impurities within the feedwater which are not boiled off with the steam will remain present in the boiler water and increase in concentration. As concentration of the dissolved solids increases the foam bubbles tend to become more stable and less vulnerable, this helps to increase foaming as the agitation of the boiling water isn't bursting the bubbles.Get Price
