✦ Synopsis
Nitric oxide reduction by carbon monoxide over calcined limestones is enhanced by the coexistence of sulphur dioxide over a temperature range pertinent to fluidized-bed combustion. This demonstrates that the reduction of nitric oxide formed in fluidized-bed combustion of coal is promoted by simultaneous sulphur retention under a staged air firing. Thermogravimetric analysis indicated that the enhanced reduction of nitric oxide was attributed to the increase in catalytic activity of the calcined limestones used partially for sulphur retention.
