REDUCTION OF NOx VIA COAL COMBUSTION CATALYSIS

The primary objective of this investigation is to determine the effect of different iron catalysts on the production of NO{sub x} during fuel-rich and fuel-lean combustion of coal. Iron in various forms and quantities will be introduced with the pulverized coal and tested in a laboratory-scale combustion furnace. The testing protocol is based on simulation of the near burner region in a full-scale boiler. This semi-annual report describes the selection of the iron catalysts used in the program as well as catalyst preparation. A detailed description of the combustion reactor and ancillary equipment is provided combined with a discussion of the test procedures. The first preliminary data have been collected and are presented followed by the plans to complete the project over the next six months
