Foaming and priming in boilers - Lenntech

Causes, and prevention of foaming and priming in boilers, prevention 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.

KEY COMPONENTS OF BOILERS | Boilers Guide

For example, if the event pressure in the boiler exceeds the pressure limit setting, the fuel valve is closed to prevent an unsafe, high pressure condition. The safety circuit of a flame safeguard control system typically includes switch contacts for low water cutoff, high limits, air providing switches, redundant safety and operating controls, and flame detectors.

Difference Between Low- and High-Pressure Boilers | Hunker

A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.
