The objective of this report was to provide an evaluation of boiler performance and environmental emissions when combusting densified forms of refuse-derived fuels (dRDF) in a military scale (40 to 300 MBTUH capacity) spreader stoker fired boiler. The boiler tested was located in Building 1240, Heating Facility at Wright-Patterson Air Force Base, Ohio. The field tests were designed to investigate: the material handling characteristics of RDF; boiler performance, i.e., boiler efficiency, spreader limitations, HTHW production, combustion properties, slagging, fouling, and clickering; and, environmental emissions, i.e., electrostatic precipitator performance, particulate emissions (size, mass rate, and resistivity), gaseous emissions, and trace metal emissions. The test demonstrated that firing unblended dRDF can be performed with minimal impact on the operational performance of a military hot water generator operated at one-third of its capacity. The boiler burned well with adequate fuel burn-out and boiler response. A 3.5% percent decrease in efficiency occurred during RDF firing. There was no significant change in electrostatic precipitator removal of particulate emissions as a result of firing RDF compared with coal. Some heavy metal emissions (nickel, zinc, chromium) were higher for RDF than coal.
