R. …Boiler tubes tend to accumulate soot from the combustion of coal in the furnace and the deposits made impede the heat transfer process hence reducing the efficiency of the thermal plant. To counter soot build-up on the tubes, thermal power plants make use of sootblowers that blow either water, steam or air on the deposits thus disintegrating them from the tubes.

Scaling in boilers - LenntechThis ratio depends on two factors: boiler pressure and boiler water pH. The value of the ratio increases almost logarithmically with increasing pressure and decreases with increasing pH. If the silica enters the boiler water, the usual corrective action is to increase boiler blowdown, to decrease it to acceptable levels and then to correct the condition that caused the silica contamination.Chemical cleaning of furnaces, heaters and boilers …The present invention is applicable for any type and size of furnaces or boiler such as square or cylindrical, with horizontal or vertical tubes and with or without convection section or economizer. The cleaning can be performed on both radiant section and convection section of the furnace or boiler as well as on the incoming air pre-heater, the economizer, the super heater and other parts of

A boiler is a pressure vessel that is designed to generate heat, produce steam or cool gases. Typically built as a rectangular or cylindrical tube, the vessel is closed at both ends and is fully insulated. Fuels such as wood, coal, oil, or natural gas power the device, making it possible for pressures of 30 bar and more to be created inside.
