【 摘 要 】

The goal of this project was to identify the primary ash mechanisms related to grate clinkering and heat exchange surface fouling associated with cofiring coal and biomass-specifically wood and agricultural residuals-in grate-fired systems, leading to future mitigation of these problems. The specific technical objectives of the project were: Modification of an existing pilot-scale combustion system to simulate a grate-fired system; Verification testing of the simulator; Laboratory-scale testing and fuel characterization to determine ash formation and potential fouling mechanisms and to optimize activities in the modified pilot-scale system; Pilot-scale testing in the grate-fired system. The resulting data were used to elucidate ashrelated problems during coal-biomass cofiring and offer a range of potential solutions.
