Boiler water can permeate the porous deposit resulting in localize corrosion. When it is coupled with significant heat flux, concentration of the boiler water occurs rapidly speeding the corrosion. The corrosion action is a result of the formation of caustic-ferritic compounds through the dissolving of the protective magnetite film.

If your steam boiler has only a manual valve for adding water, until you know the system's rate of water usage, you should check the water level at least once a week during the heating season. You'll want to add water whenever the sight glass shows that the water level has dropped to the "add" mark and you should always see some water in the sight glass.

Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.

2021/10/21 · If the boiler pressure is only raised to 1½ bar, with the system cold no water enters the expansion vessel as the water pressure is not enough to compress the air within the expansion vessel. However, as the system heats up, the water pressure will increase and water will start to enter the expansion vessel, compressing the air pocket on the other side of the diaphragm.

In addition, some boilers also have a blowdown off take located slightly below the water level in the steam release area. A small amount of water is continuously removed through these connections. The use of continuous blowdown in addition to manual (bottom) blow down maintains the residuals at more consistent levels in the boiler water.
