Assessment of Existing Equipment when Converting to

Generally, during startup of a coal‐fired boiler the operator slowly heats the boiler to avoid problems with boiler expansion and overheating of equipment (e.g., reheaters, superheaters). 9 If the boiler is offline for a short time and does not experience significant temperature declines,

Coal Fired Boiler Emissions Test - EPA

Jun 15, 1994 · Unit One is a pulverized coal-fired, dry bottom boiler with an opposed firing configuration. Low NOx burners are used to control NOx emissions. Normal operating temperature in the combustion zone is approximately 2,000 - 3,000 degF. The boiler produces 4,500,000 lb/hr of steam for a General Electric steam turbine generator rated at 688 MWe.

Evaluation and mitigation of visible acidic aerosol plumes

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 ).
