  1. Status Report to the Stationary Sources Joint Forum: Task 2: Control Technology Analysis February 23, 2005 Presented by: Eastern Research Group, Inc.

  2. Overview Objective: Provide costs and impacts for options used to control emissions of NOx, SO2, PM, VOC, and Ammonia NOx from EGUs • EGUs firing coal – focus of work has been on this category. • EGUs firing oil and gas - Database of sources has been assembled. Includes baseline NOx emissions and existing controls. Other • Analysis will start after NOx control options for coal-fired EGUs have been identified • NOx from non-EGUs • SO2 • PM, VOC, and ammonia

  3. NOx From Coal-fired EGUs • Assemble database of all EGUs in WRAP • Profile state of the art NOx combustion controls • Identify control scenario’s • Calculate costs and impacts of scenarios

  4. Assemble Database of All EGUs in WRAP • Data obtained from EPA databases • CAMD • EIA 767 • EIA 423 • Data from telephone contacts w/utilities • Coal and combustor properties • Database is available on website

  5. Information in Database • Location • Capacity (actual/nameplate) • Combustor type • Baseline emissions • Heat input • Coal moisture and nitrogen content • Combustor volume, volumetric heat rate, and residence time • CO limit • Coal mine origin • NOx regulations applicable • In-service date • Primary fuel • Wet/dry bottom • Low NOx control equipment and manufacturer

  6. State of the Art Combustion Controls • Contacted vendors and conducted literature search to identify latest NOx combustion controls • Cost and performance data • Sources in commercial use • Profiles of the newest technologies and tables summarizing their performance and costs are available on the website. • Next step • Summary table of emission limits/reductions for combinations of controls with coal type, combustor type, and combustor parameters.

  7. Control Scenarios • Control scenarios can be based on requiring a specific control technology, or meeting target emission reductions or emission limits. • One set of options can be applied to all units, or separate options can be applied to different subcategories • Next steps • Summary of initial control options

  8. Costs and Impacts of Scenarios • Costs for LNB and OFA from CAMD analysis have been updated to 2004 $. • Costs and emission reductions/limits for new state of the art controls have been provided by vendors. • After initial control scenarios are set, costs and impacts of control scenarios will be calculated
