Abstract
The report gives results of work concentrating on characterizing three process operational parameters of a technology that combines sorbent injection and selective non-catalytic reduction for simultaneous sulfur dioxide/nitrogen oxide (SO2/NOx) removal from coal-fired industrial boilers: injection temperature, sorbent type, and reductant/pollutant stoichiometric ratio. Up to 80% reduction of SO2 and NOx at reactant/pollutant stoichiometric ratios of 2 and 1.5, respectively, was achieved. SO2 emission reductions from slurry injection were enhanced moderately when compared with dry sorbent injection methods, possibly caused by sorbent fracturing to smaller, more reactive particles. Emissions from ammonia (NH3) slip (unreacted nitrogen-based reducing agent) and nitrous oxide (N2O) formation were reduced in comparison with other published results, while similar NOx reductions were obtained.
