Cynthia Schmidt Mechanical Engineering Department University of Texas Methods to Reduce Sulfur Dioxide Emissions From Coal-Fueled Utilities

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

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

Percentage Reduction of SO 2 coal cleaning coal switching fluidized bed absorption adsorption % 80% 90% 95% 80% In summary, by using these methods, coal utilities can greatly reduce SO 2 emissions Questions?

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

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

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 Winging It + sounds natural - has much room for error Speaking From Slides + insures organization + allows eye contact + allows improvising - some room for error

In summary, you can improve by practicing and by critiquing the presentations of others Cal-Tech Linus Pauling Chien-Shiung Wu AIP Richard Feynman Cal-Tech
