High Sulfur Particulate is Hot Topic Hour for Jan. 7, 2010
Control of particulates from utility boilers burning high sulfur coal will be
the "Hot Topic Hour" on January 7, 2010 at 10 a.m. CDT. The selection of the
proper technology to control particulate emissions from plants burning high
sulfur coal is likely to get much more difficult in the near future. It is very
probable that all plants will face a MACT requiring a 90 percent reduction in
mercury, SO3 and other air toxics. It is also probable that fine particulates
will be a surrogate for air toxics. Plants that previously worried about the
effect of SO3 on their particulate emissions and began to worry about the effect
of fine carbon from the injection of activated carbon for mercury reduction will
now need to look at a more complex picture. Bag houses will most likely be
required at many plants in addition to an ESP and the requirements for those
plants already equipped with fabric filters will change. But there is not a lot
of experience with bag houses on large plants burning high sulfur coal (over
2.5%).
In a previous Hot Topic Hour, several speakers discussed the affects of
temperature and moisture on the selection of bag material. Additives to control
acids were also discussed. Are there other technologies available that will meet
requirements of the expected MACT regulations especially for the smaller plants
where a bag house may not be economical? This Hot Topic Hour will build on the
previous discussion and offer additional suggestions on control of particulate
emissions.
The following speakers will discuss the future demands on coal-fired power
plants for particulate control, available technologies for particulate control
and current experience with particulate control systems at plants burning high
sulfur coal.
John R Darrow of W.L. Gore & Associates will discuss GORETM Filter Media for
High Sulfur Coal Applications. GORE expanded Polytetrafluoroethylene (ePTFE)
membrane bags are well suited for use in acid gas environments such as fly from
boilers burning high sulfur coal. This presentation outlines the available
choices of membrane laminates and discusses why membrane bags may be a good
choice for controlling particulate matter (PM).
