 Wallis
Harrison
President
Wallis has over 30
years experience in the industry, 28
years with Southern Company Services
(SCS) as Principal Research
Specialist of Research and
Environmental Affairs. He is a long
standing member of the International
Society for Electrostatic
Precipitation (ISESP) and serves on
the Board of Directors of the ISESP.
While at SCS he
directed or participated in the R&D
of numerous solutions for utility
power plant problems, including,
noise and vibration problems, heat
rejection with cooling towers, fluid
and gas flow problems, and air
quality emissions related to SOx,
NOx, and particulate.
Beginning in 1978,
his involvement in problem solving
with the electrostatic precipitators
within SCS, yielded many
improvements to their existing ESPs.
Wallis was the first person to add
Sodium to a Hot-side precipitator to
improve its performance, which is
now a standard treatment for poor
performing Hot-sides.
During his many
years, as a member of the Electric
Power Research Institute (EPRI)
Particulate Control Advisory
Committee, he directed and performed
most of the particulate control
research conducted in the US. Wallis
was principal author for the first
EPRI Electrostatic Precipitator
Guidelines Manuals. He installed the
first COHPAC II pilot facility,
where a pulse jet baghouse is
contained within the same casing as
the ESP and directed the research
that led to the installation of two
250 MW COHPAC I bag houses.
In 2001, Wallis
introduced the Indigo Bi-polar Fine
Particulate Agglomerator technology
to the US, and installed the 2nd and
3rd full scale Indigo Bi-polar Fine
Particulate Agglomerators in the
World.
Among his other
talents, Wallis manufactures and
distributes world wide, the Southern
Research Institute designed,
Point-Plane resistivity probe for
in-situ measurements of fly ash
resistivity. He has also designed
and manufactured a wide variety of
custom test equipment for utility
boiler testing. He took a Plexiglas
model of the 5 port pitot probe, and
manufactured the first 5-port
spherical pitot probe that could be
used in actual power plant
applications for the measurement of
three-dimensional turbulent flow.
The subsequent use of these 5 port
pitot probes convinced the U.S. EPA
to change their measurement
methodology for turbulent flows. |
