WhatsApp: +86 18203695377The workings of a boiler are very simple and easy to understand. As we know, a boiler is a closed vessel where water is stored first. Fuel is burned in a furnace, and water is converted into hot gases. These hot gases come into contact with water vessels, where the heat of such gases transfers to the water. Hence, steam is produced in the boiler.
WhatsApp: +86 18203695377Coalfired boilers are mainly operated at either subcritical or supercritical conditions. From a thermophysics 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 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).
