The report gives a projection of the performance and cost of the Exxon Thermal DeNOx Process applied to coal-fired utility boilers. Eight units were selected, representing different boiler manufacturers, sizes, firing methods, and coal types. Thermal DeNOx performance was projected both with and without combustion modifications for all boilers at full load and at one or more loads down to 50%. Three NOx reduction targets were used: the proposed New Source Performance Standards (NSPS), reduction to about two-thirds of the proposed NSPS, and the maximum practical NOx reduction that could be achieved. All costs are for full load. Thermal DeNOx was projected to be equally applicable for all boilers studied, despite significant differences in flue gas temperatures and flow paths. Maximum Thermal DeNOx performance ranged from 50 to 59% for the boilers studied. Costs ranged from 0.25 to 1.23 mills/kWh, excluding preliminary engineering costs and licensing royalties. A full-scale demonstration of Thermal DeNOx on a coal-fired utility boiler is recommended, including investigation of potential downstream effects of the process.
