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

Jul 05, 2009 · Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss. There are a few minor losses in boiler which can also

Improve Your Boiler's Combustion Efficiency

On well-designed natural gas-fired systems, an excess air level of 10% is attainable. An often-stated rule of thumb is that boiler efficiency can be increased by 1% for each 15% reduction in excess air or 40°F reduction in stack gas temperature. Suggested Actions Boilers often operate at excess air levels higher than the optimum.
