Direct sorbent injection for combined SO/sub 2//NO/sub x/ removal: Quarterly technical progress report, January-March 1987
1987
With the growing concern over the emission of sulfur and nitrogen oxides from large scale coal fired boilers and the widely held belief that these emissions are precursors to acidic deposition, there is a growing interest in finding effective means of retrofitting existing boiler plants with SO/sub 2/ and NO/sub x/ emission control systems. The project objective is the experimental verification of a low cost system for simultaneous SO/sub 2/ and NO/sub x/ control technology. The system selected will be configured to require minimum capital cost and minimum additional space. SO/sub 2/ and NO/sub x/ reduction to the maximum degree that is economically attractive is sought. The approach taken is to inject active SO/sub 2/ and NO/sub x/ sorbents into a flue gas stream that simulates flue gases from a large scale coal fired boiler. The project will also include mathematical modeling to reduce the data and to extend the results to larger systems. 10 refs., 45 figs., 32 tabs.
