Abstract
If the nation is to continue to use one of its major indigenous energy sources, coal, for power generation, cost effective emission control technologies must be found for acid rain precursors in order to safeguard the environment. Gas reburning with sorbent injection (GR-SI) is a retrofittable technology which is generally applicable to a wide range of both wall-and corner-fired boilers. GR-SI reduces both acid rain precursors and is therefore an effective acid rain control strategy. It is a combination of two technologies: reburning for in-furnace NO/sub X/ control and the injection of a calcium-based sorbent in the furnace or convective path of a pulverized coal-fired boiler for in-situ SO/sub X/ removal. The cost effectiveness of GR-SI is dependent upon two factors - the cost of natural gas and sorbent cost/utilization. 7 references, 4 figures.
