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 types of

Feedwater Temperature - Boiler, Cooling and Wastewater

What is a target temperature for your feedwater? Efficiently running systems will maintain a feedwater temperature above 180 degrees F. This maximizes the amount of condensate that is returned and combined with the colder makeup water, resulting in a pre-heated inflow to the boiler. What happens when the feedwater temperature is below 180
