Boilers are classified into fire-tube and water-tube types. Steam is generated by heating water in the boiler.
Fire-tube boilers have hot gases from combustion passing through tubes which are surrounded by water.
Water-tube boilers have water flowing through tubes which are heated by hot gases from combustion.
Steam is generated when water is heated in the boiler and the resulting steam is used for various applications su...
Boilers produce two types of steam: saturated and superheated.
Saturated steam is produced when water is heated to its boiling point and vaporizes with no further increase in temperature.
Superheated steam is produced when saturated steam is heated above its boiling point, resulting in a higher temperature and energy content.
Saturated steam is commonly used for heating and power generation, while superheated steam is use...
