COAL-FIRED UTILITY BOILERS: SOLVING ASH

The accumulation of slagging and fouling ash deposits in utility boilers has been a source of aggravation for coal-fired boiler operators for over a century. Many new developments in analytical, modeling, and combustion testing methods in the past 20 years have made it possible to identify root causes of ash deposition. A concise and comprehensive guidelines document has been assembled for

Co-firing of biomass in coal-fired utility boilers

Downloadable (with restrictions)! Co-firing tests with sawdust and coal have been carried out at FORTUM's Naantali-3 CHP power plant (315 MWfuel). The Naantali-3 plant is a tangentially-fired pulverised-coal unit with a Sulzer once-through boiler that produces 79 MW electricity, 124 MW district heat and 70 MW steam. Naantali-3 is equipped with roller coal mills (Loesche), modern low-NOx

Prediction of Performance From PRB Coal Fired in

Present regulatory requirements enforces the modification of the firing modes of existing coal-fired utility boilers and the use of coals different from those originally designed for these boilers. The reduction of SO 2 and NO x emissions were the primary motivation for these changes. However, economic considerations played a major role too.
