mechanical cleaning boiler water tubes

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

Mechanical Cleaning of Boiler Fire Tubes- Rotary Cleaning
The mechanical cleaning of boiler (fire) tubes is a very effective method to clean boiler (fire) tubes. This method is based on the use of a tube cleaning machine, flexible shaft (various lengths) and brushes or heavy-duty cleaning tools. The machine powers a flexible shaft, which then rotates a brush in the tube.

Waterside Boiler Cleaning - Controlled Combustion
The waterside of a heating unit is where the boiler water is present, this water is heated through thermal conduction, creating steam. Over time, scale deposits are formed when calcium, magnesium, and silica, commonly found in most water supplies, react to form a continuous layer of material on the waterside of the boiler (boiler tubes, surrounding steel, etc.).
