McIlvaine will Present Information from Power-Gen Papers in Various Ways

A number of good papers were presented at Power-Gen Orlando. They included information not already in the Power Plant Air Quality Decisions. A specific agenda as to how we will report on these papers and extract further information follows:

Session: FGD RETROFIT TOPICAL ISSUES

Date: 11/29/2006

Chair: Mr. Michael Salerno, ALSTOM Power

Co-Chair: Richard Dunn

COMPARISON OF ECONOMIC AND TECHNICAL FEATURES OF FLUID BED AND SPRAY DRYER FGD SYSTEMS

Anthony Licata and Richard Abrams, Babcock Power Environmental Inc.;

Douglas J. Roll, P.E., AES Greenridge LLC;

Dr. Harald Reissner, Austrian Energy & Environment AG

· IMPORTANCE:  FIRST U. S. INSTALLATION OF A CFB

SCRUBBER DESIGN BY BABCOCK AND AE&E.

THE REAL COST OF FGD RETROFIT PROJECTS

Thomas Meehan and Peter Kelly, Sargent & Lundy

· IMPORTANCE: VERY GOOD ANALYSIS OF THE VARYING COSTS OF SUB-SYSTEMS ON OVERALL FGD COST. SINCE TOTAL FGD COST IS SOARING, THIS IS VERY TIMELY.

· ACTION:  CONTACT AUTHORS FOR AUDIO/VIDEO USING POWER POINTS, WRITE ARTICLE IN JANUARY FGD NEWSLETTER AND ADD PAPER TO COST SECTION OF FGD DECISION TREE.

THE USE OF FRP (FIBERGLASS-REINFORCED PLASTIC)

IN FGD APPLICATIONS

Don Kelley, Ashland Specialty Chemical

· IMPORTANCE:  FRP IS WIDELY USED IN STACK LINERS AND COULD FIND GREATER USE IN DUCTS AND SCRUBBER VESSELS DUE TO ALLOY COST INCREASES.

· ACTION: CONTACT AUTHOR TO PARTICIPATE IN HOT TOPIC HOUR ON CORROSION MATERIALS, JANUARY 11, 2007.  ALSO CONTINUE TO CONSIDER PARALLEL DISCUSSION IN CHINESE. CONSIDERABLE INFORMATION IS ALREADY IN THE FGD DECISION TREE BUT IT MAY NEED UPDATING.

NEXT GENERATION FGD

Michael T. Hoydick, Wheelabrator Air Pollution Control Inc.;

Ronald Gregory and Duane Braunecker, Western Kentucky Energy

· IMPORTANCE: 99% SO2 REMOVAL OBTAINED. PARTICULATE REMOVAL PERCENT IS ALSO HIGH AND VARIES DIRECTLY WITH THE INLET LOAD.  THIS IS VERY SIGNIFICANT FOR FGD RETROFITS WHERE EXISTING PARTICULATE LEVELS NEED TO BE REDUCED.

· ACTION:  CONTACT AUTHORS AND ARRANGE AUDIO/VIDEO INTERVIEW WITH POWER POINTS FOCUSING ON THESE TWO PERFORMANCE PARAMETERS.

A REVIEW OF DYNAWAVE® FGD TECHNOLOGY
Larry Paschke, MECS, Inc.

· IMPORTANCE:  ALTERNATIVE TO SPRAY TOWER WITH GOOD MASS TRANSFER CAPABILITIES.

· ACTION:  ARRANGE FOR AUTHORS TO PARTICIPATE IN THE HOT TOPIC HOUR ON JANUARY 18, 2007 DISCUSSING VARIOUS LIMESTONE SCRUBBER DESIGNS.

· IMPORTANCE: ABILITY OF SPRAY DRIER TO MEET COMPLIANCE EFFICIENCY REQUIREMENTS IS VALIDATED.

· ACTION: OUR RECENT SPRAY DRIER VS. CFB HOT TOPIC HOUR RAISED QUESTIONS ABOUT SPRAY DRIER EFFICIENCY WHICH ARE PARTIALLY ANSWERED BY THIS EXPERIENCE. WE WILL THEREFORE CONTACT THE AUTHOR ABOUT AN AUDIO/VIDEO USING POWER POINTS. ALSO WE WILL SEEK TO INCLUDE SOMEONE FROM TUCSON ELECTRIC IN THE INTERVIEW AS WELL. THERE WAS NO PAPER IN THE PROCEEDINGS, SO WE NEED MORE DETAILS FOR THE NEWSLETTER AND DECISION TREE.

Alternate Paper

FACTORS IN THE PRODUCTION OF COMMERCIAL-GRADE GYPSUM BY ELECTRIC UTILITY FGD SYSTEMS

Michael L. Meadows, P.E., Black & Veatch Corp.
