  • Water Levels in Steam Boilers | Spirax Sarco

    The task of any steam boiler is to provide the correct amount of high quality steam: safely, efficiently, and at the correct pressure. Steam is generated by heat from the combustion of fuel in a furnace, or by waste heat from a process. The heat is transferred to water in the boiler shell, which then evaporates to produce steam under pressure.Learn More
