This paper discusses the effect of the atomization characteristics of BioLime (a biomass based pollution control material developed by DynaMotive Technologies Corporation), on the SO{sub 2} and NOx reduction performance. The tests were conducted in a 500,000 Btu/h Down Fired Combustor at The Pennsylvania State University firing pulverized, high sulfur coal. The effect of the temperature at the injection location, atomization air pressure, and the influence of the delay in the supply of air for the combustion of the BioLime were investigated. Atomization was performed using both air and nitrogen. A simultaneous reduction of 90% SO{sub 2} and 50% NOx emissions was obtained during the tests at approximately Ca/S ratio of 1. Optimum temperature for BioLime injection was found to be between 2,000--2,050 F. BioLime atomization air pressure was varied from 20 to 100 psig and the optimum pressure was found to be 50--60 psig. The location of BioLime combustion air injection influenced the reduction of NOx to N{sub 2} by reduction. Carbon monoxide emissions were observed to be lower when using BioLime than the baseline emissions with coal. BioLime is made by processing lime and pyrolysis oil from biomass.
