Water Levels in Steam Boilers | Spirax Sarco

Water Levels in Steam Boilers. 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

What is a Waste Heat Boiler? (with picture)

A waste heat boiler uses the heat formed as a byproduct of another process, heat which would normally be wasted, and uses it to create steam. The steam can be used to drive turbines which produce electricity. Alternatively, the boiler can simply be used to heat water or other kinds of fluid.

Thickness of Inconel Coatings on Boilers | Heat Recovery

Energy that would otherwise be lost in discharged exhaust is captured and reclaimed in waste heat recovery boilers. The hot flue gas is fed into the boiler where it heats up water flowing through pipes within the housing, producing either hot water for use in other industrial purposes or, depending on the temperatures involved, steam that powers a gas turbine to generate electricity.
