The objective of this project is to demonstrate gas reburning-sorbent injection (GR-SI) emission control technology on three pre-NSPS coal-fired utility boilers in Illinois. The goals are to achieve NO{sub x} and SO{sub x} emission reductions of 60 and 50% respectively. During this quarter, work progressed on all tasks of this project, except for Task 3, Engineering Design, which awaits NEPA approval. The selection of the three primary host sites was confirmed through site characterization and SO{sub x}/NO{sub x} control performance predictions. All three boilers selected (tangentially, wall and cyclone fired units) can meet the NO{sub x} and SO{sub 2} targets of 60% and 50% respectively. Internal and external communications were established and meetings to be held in December were planned. EER continued its dialogue with potential boiler manufacturer subcontractors and electrostatic precipitator specialists. The latter area was necessitated by the need to upgrade ESP performance when using sorbent injection. Process design studies are in progress to achieve the process specifications required for detailed engineering design. In the environmental area, good progress was made in generating Environmental Information Volumes for each site, the Environmental Monitoring Outline and defining the permitting assistance to be provided to the host sites.
