Annually renewed contract to provide engineering design input and testing
technical support for all combustion related NOx control projects.
 Design and implementation of OFA system (including cyclone burner
modifications), for Indiana and Michigan Power’s Tanners Creek Unit 4,
500 MW supercritical cyclone fired unit. Achieved approximately 80%
reduction in full load NOx emission rate.
 Design and implementation of OFA system and burner zone
modifications for Kentucky Power’s Big Sandy Unit 1, 265 MW opposed
wall, pulverized coal fired unit. Unit achieves an additional 30%
reduction in NOx emissions. Riley Power’s CCV low NOx burners
installed in 1998. Project also included development and application of
hopper purge air.
 Design and implementation of OFA system (including cyclone burner
modifications), for Columbus and Southern Power’s Conesville Units 1
and 2, 2x125 MW cyclone fired units. Achieved approximately 65%
reduction in full load NOx emission rate.
 Design and implementation of burner modifications for Indiana and
Michigan Power’s Tanners Creek Units 1-3 (2x150 MW and 1x200
MW), Ohio Power’s Philip Sporn Units 1-4 (4x150 MW), and
Appalachian Power’s Kanawha River Units 1and 2 (2x200 MW) and
Clinch River Units 1-3 (3x200 MW). All are roof-fired steam generators,
originally designed by B&W. Original low NOx combustion system was
designed and patented while an AEP employee. Recent modifications
were to accommodate deeper staging levels for further NOx emission rate
reductions.
 Provide technical review of Alstom LNCFS Level II NOx control
installation for Columbus and Southern Power’s Conesville Unit 4, 800

granular ash particles to electrostatic precipitator at Ohio Power’s
Kammer Units 1-3, 3x210 MW front wall cyclone fired. Data to date
indicates that LOI reduced by a third at consistent cyclone staging and
NOx emissions. Granular ash carry-over has been reported to be minimal
and slag coating within the cyclone barrels has been notably improved.

Other less recent projects have included:
Arizona Public Service (1999)
Four Corners Unit 2 opacity ascendances due to combustion modifications:
severe levels of unburned carbon in ash particularly during load cycling was
producing very dark stack plume, visible for miles. This problem was attributed
to the operation of the milling system producing end to end flow swings. This
coupled with the segregation of the mill ends to the left and right side of the units
during the burner modifications was creating corresponding excess air swings
left to right on the unit. The rich conditions that resulted produced unburned
char in the flue gas. With no electrostatic precipitator and the wet scrubber’s
ineffectiveness in collecting the carbon, the dark plume conditions were
produced. SAVvy Engineering was contracted to help evaluate the combustion
problem and adjust burners to help mitigate the problem. Elevating the excess
air in anticipation of load swings was recommended as a short term measure.
Restoration of the milling system to help mitigate end to end flow swings from
the ball tube mill were included in long term recommendations. This included
 restoration of heated air to the pocket/overshot feeders to minimize coal
caking within the feeders,
 restoring the inlet crushers and pre-dryer and/or adding specified
perforated inlet plates to the primary air supply ducts to improve
measurement and balance of primary airflow to the two ends of the mill’
 upgrade the original heart style classifier to centrifugal classifiers, and
 restore original coal conduit layout that blends any flow mal-distribution
from a mill within the furnace.
