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 ).

•Start ID/FD/APH Systems as per normal start up procedure. •(Respective Testing Schedules or O&M manual to be referred) and establish required furnace draft (Around –5 to –10 mmwc) •Charge SCAPH and raise the air temperature to around 600C. •Adjust the boiler …
Coal fired boilers are major energy consuming equipment's for process industry and care to be taken to improve performance of coal fired boiler. Boiler performance depends on various operation parameters and external factors.
The boiler should be safe under operating conditions. (ii) Accessibility. The various parts of the boiler should be accessible for repair and maintenance. (iii) Capacity. The boiler should be capable of supplying steam according to the requirements. (iv) Efficiency. To permit efficient operation, the boiler should be
