Coal-Fired Boiler - an overview | ScienceDirect Topics

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).

Coal fired boiler: How to derive optimum efficiency

Boiler efficiency is based mainly on the quantity of loss suffered by the system. In case of pulverized, high-capacity coal fired boiler, loss amounts to approximately 12-14 percent. 50 percent of losses are governed by different fuel properties such as moisture present in fuel, hydrogen in fuel including ambient air conditions.The remaining 50 percent losses are attributed to dry gas loss and
