Transcripción del resumen presentado por el autor, en inglés: Solutions for simultaneous firing of biomass and other opportunity fuels with coal have gained increasing interest in the recent past. Several utilities are taking advantage of co-firing cost-effective biomass fuels with pulverized coal to reduce SO2, NOx and mercury emissions, and to increase the production of environmentally advantageous, renewable green power. Biomass or opportunity fuel co-firing can be retrofit to most pulverized coal units. Full load coal capability, NOx emissions, boiler performance and equipment integration and long term reliability are major considerations when modifying low NOx combustion equipment to include biomass or other co-firing fuels. The paper presents the design considerations when biomass or opportunity fuels are to be fired in wall-fired pulverized coal boilers. Results of computational fluid dynamic (CFD) simulations are shown to highlight the differences in fuel behavior and the challenges that arise from the dissimilar fuels. Installing a burner specifically designed for firing two or more dissimilar fuels can optimize co-firing. The paper outlines the design concepts applicable to this approach to biomass co-firing.
