Reliable Coal Fired Boiler Design


Challenges when Converting Coal-Fired Boilers to Natural Gas

Riley Power recently participated in field testing on a wall fired boiler rated at 1,779,000 lb/hr of main steam flow. The boiler is an opposed fired design with two (2) levels of burners on both the front and rear walls. The natural gas supply system to the boiler utilized a single flow control valve for all the burners.

Boiler design for ultra-supercritical coal power plants

Jan 01, 2013 · 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).
