Foaming and priming in boilers - Lenntech

Boiler water carry-over is the contamination of the steam with boiler-water solids. Bubbles or froth actually build up on the surface of the boiler water and pass out with the steam. This is called foaming and it is caused by high concentration of any solids in the boiler water. It is generally believed, however, that specific substances such as alkalis, oils, fats, greases, certain …

4.5 Steam Turbines and Rankine Bottoming Cycle

4.5.2.2 Boilers. Steam turbines differ from reciprocating engines and gas turbines in that the fuel is burned in a boiler that is separate from the power generation equipment, the steam turbo-generator. The energy is transferred from the boiler to the turbine by an intermediate medium, steam under pressure.
