What to do if your boiler loses pressure - British Gas

The position set when the boiler was installed is sometimes shown by a red indicator needle. On most digital gauges, you'll see a flashing pressure reading, if there's a low (or high) pressure warning. If your boiler pressure reads less than 1 bar, it's possible that you might have lost water from the system, which needs to be replaced.

How Is The Low Temperature Corrosion of Boiler Caused

Low temperature corrosion often occurs in the air preheater, but when the fuel sulfur content is higher, the boiler air coefficient is larger, so that SO3 in the flue gas content is higher. The dew point is higher, and the water supply temperature is low, the economizer tube may also occur low temperature corrosion.

Water-tube boiler - Wikipedia

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes

Water Level Controls and Devices - National Board

A low-water fuel cutoff is used on both steam and hot water boilers to shut off the fuel or source of heat when the water drops below a predetermined, safe operating level. The most common type of low water fuel cutoff is a float inside a chamber. The float mechanism actuates an electrical switch when the float reaches a preset level.
