Abstract
The paper reports the progress principally of design-related phases of a demonstration of reburning on a large cyclone-fired boiler, for which coal is the primary fuel and natural gas, the reburn fuel. Reburn system design criteria are presented, as well as the methodology and results of the cold-flow modeling evaluation which was used to identify existing boiler aerodynamics and help to determine the optimum configuration for reburn fuel and additional air injectors. Mathematical modeling was conducted to determine potential effects of a reburn system on boiler thermal performance. Experience is cited regarding effects of low air/fuel stoichiometric conditions on boiler tube wastage. Finally, a current-day economic analysis is presented which is specific to the described demonstration.
