A steam boiler is a steam producing heating system; it produces energy by heating water to create steam. A steam boiler burns fuel to heat water. The combination of heat and water produces steam. Steam boilers are defined by their construction, portability, types of tubes, types of fuel, and the pressure they produce.

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C ( Shen and Cheng, 2004 ).
