Title
Three classes of methods exist forreducing emissions of sulfur dioxide
post-combustionmethods
combustionmethods
pre-combustion methods
Mapping
Middle
Coal switching and coal cleaningare two pre-combustion methods
Coal CleaningCoal Switching
High Sulfur Mine Low S ulfur Mine
Middle 1
The most effective combustion methodis an atmospheric fluidized bed
separator
airinlet
cleanedexhaust
grid
90% removal capability
Low capital cost—can usein existing equipment
High operating cost
Ability to use differentgrades of coal
Middle 2
Ending
By using these methods, coal utilitiescan greatly reduce SO2 emissions

Presentations can be viewed from three stylistic perspectives

Archives, Cal-Tech
Visual Aids
Delivery is the speaker’s interaction with the audience

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
