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.

1982/1/1 · Water-treatment Processes. Water-treatment processes for boiler feed preparation are of two kinds: (a) those that remove the calcium and magnesium ions which are the main offenders in scale-forming processes, and (b) those that also remove all or part of the dissolved solids. There are four processes chiefly used: 1.

Caustic corrosion in boilers. Concentration of caustic (NaOH) can occur as a result of steam blanketing (which allow salts to concentrate on boiler metal surface) or by localized boiling beneath porous deposits on tube surface. Caustic corrosion occurs when caustic is concentrated and dissolves the protective magnetite (Fe 3 O 4) layer, causing

Steam Superheaters in Industrial Boilers The Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler. It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to superheat the

The pressure of steam used for heating is limited to 1 barg (15 psig), corresponding to a temperature of 120 C, with the steam saturated rather than superheated. If the flow to the vaporizer is excessive, the heating is insufficient or the heat transfer surfaces are fouled, the chlorine vapor may lose superheat, liquid droplets may be entrained, or the vaporizer may flood.
