  4. Methods to ReduceSulfur Dioxide EmissionsFrom Coal-Fueled Utilities Cynthia Schmidt Mechanical Engineering Department University of Texas

  5. Three classes of methods exist for reducing emissions of sulfur dioxide pre-combustion methods combustion methods post-combustion methods

  6. 90% removal capability low capital cost—able to use in existing equipment high operating cost ability to use different grades of coal cleaned exhaust separator grid air inlet The most effective combustion methodis an atmospheric fluidized bed

  7. In summary, by using these methods, coal utilities can greatly reduce SO2 emissions coal cleaning coal switching fluidized bed absorption adsorption 40% 40% 80% 90% 95% 80% 25 50 75 Percentage Reduction of SO2 Questions?

  8. Avoid filler information Avoid long lists • Corrosion • Acid rain • Toxic materials • Pulsed combustion • Energetic materials • Pyrogenic materials • Smog Roentgen discovered x-rays in 1895. He found that a cathode-ray tube produced fluorescence in a distant plati- num-barium-cyanide screen. Avoid complex images DEAR- ATOR HOT WELL RGF B A Exclude details that the audiencedoes not need or cannot remember

  9. Presentations can be viewed from three stylistic perspectives Structure and Speech Visual Aids Delivery Archives, Cal-Tech

  10. Delivery is the speaker’s interaction with the audience AIP Cal-Tech Voice Cal-Tech Movement Stage Presence

  11. You have several choices for how you deliver your speech Memorizing the Speech + allows eye contact - difficult for long speeches - room for precision errors - no room for improvising Reading From a Text + ensures precision - does not sound natural - no room for improvising - hinders eye contact Speaking From Slides + insures organization + allows eye contact + allows improvising - some room for error Winging It + sounds natural - has much room for error

  12. In summary, another way to approach presentations is to focus on three critical steps for success AIP Have an acute awareness of the audience Cal-Tech Be genuinely enthusiastic about the subject Cal-Tech Know the subject
