Principles of fuel blending applied to cofiring of biofuels in coal-fired boilers
- Foster Wheeler Environmental Corp., Sacramento, CA (United States)
Cofiring of biofuels with coal in cyclone and pulverized coal (PC) utility boilers is becoming commercial practice in areas with abundant wood waste or other biomass materials, as a means for achieving one or more goals: providing customer service, reducing SO{sub 2} and No{sub x} emissions, reducing fossil CO{sub 2} emissions to meet voluntary greenhouse gas reduction targets, and reducing fuel costs when possible. Significant testing of cofiring has been performed by Foster Wheeler Environmental for the Tennessee Valley Authority (TVA) and the Electric Power Research Institute (EPRI). This testing has occurred at the Allen Fossil Plant, a cyclone boiler of TVA. It has occurred at the Kingston Fossil Plant, a tangentially-fired (T-fired) PC boiler of TVA. It has occurred at the Shawville Generating Station of Penelec/GPU. From these tests, and from extensive laboratory research and engineering studies, certain principles of fuel blending have emerged: (1) focus upon the objectives of cofiring and fuel blending, (2) focus upon the techniques required to achieve the desired results, (3) focus upon fuel and boiler limitations that may be impacted by blending, and (4) carefully evaluate the fuel chemistry involved in the blending. Within these principles, Foster Wheeler has defined certain mechanisms of combustion that can be manipulated by fuel blending, either to address the boiler limitations or to achieve desired goals. 6 refs., 1 tab.
