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 ).

How to Run a Coal Fired Boiler at the Best Efficiency

Jan 28, 2009 · Jan 28, 2009 · Coal burns in the furnace giving out heat and forming flue gases. Induced Draft Fan. The hot flue gases from the furnace is drawn out by the Induced draft fan. The gases passes through the various heating surfaces of the boiler, the Electrostatic Precipitator and discharges to the atmosphere at the top of the stack.

How Power Plant Boiler Works? How Combustion System in

Fuel used in the boiler should be combusted completely to get complete heat of fuel. Due to low oxygen supply or uneven oxygen supply there may be changes of incomplete combustion of fuel. Incomplete combustion will reduce boiler efficiency drastically, it must be checked regularly and controlled by proper combustion system.

ignition, bringing the boiler up to normal operating conditions, and preparing and pressurizing the steam headers. Ignition Although boilers have many different specific ignition systems, they all follow the same basic sequence of steps: 1. Pre-purge of the furnace. 2. Reduction of air flow for stable ignition. 3. Pilot burner ignition 4.
