based on experience and O2 analyzer indications. There are no CO analyzers in the power

3.8 Environmental Issues
Prior to 1988 all environmental checkmg was carned out by central group usmg portable
equipment. After 1988 the statIOn has taken over thIS work. The checks are carned out once
per month usmg portable eqUIpment the locatIOn being determined by the prevailing wmd
direchon. The measurements are taken at 2.5km, 5km, 8km, 15km, 20km and 30km dIstance
from the stahon. SOlI and water monitonng IS carned out local to station, and the cooling water
inlet and outlet conditions are momtored. All water runmng off the ash dump SIte IS monitored.
The test well water is checked for heavy metal contammation. In conJunchon with the KIev
Botanical Institute the area up to 30km distance IS checked. A lattice network IS momtored for
ground condihon and comparIson between areas recorded.
The power plant has made modIficatIOns to the boilers to reduce NOr
3.9 Future Plans
IMPRESSARIO AGRUPADOS, an engineering consulhng firm from Spam conducted a major
rehabilitation study in 1993 for EBRD. They evaluated seven alternatives for rehabilItation,
including rebuilding bOIlers and replacmg bOIlers WIth circulatmg fluidIzed bed (CFB) bOIlers,
and gas turbme combmed cycle repowenng.
The plant is very much mterested m learnmg more about CFB technology as a solution to the
problems resulting from poor coal - S02, NO x , and hIgh maintenance on the old Taganrog PC
bOIlers. They are also mterested m western technology for mstrumentahon and control, and
want to upgrade the automatIOn on the rehabIlItated block 12 as a demonstration project.
Expenence gained from application of a DIstnbuted Control System (DCS) to block 12 would
be applied to the 1995 reconstructIOn of blocks 11 and 7.
They are planning to add one or two gas fired peaker boilers to meet additIOnal hot water district
heating demand from city.
3.10 Inspection. Assessment. Comments
•
•
The stahon IS well managed by expenenced personnel. The engmeenng staff IS
competent. There IS a need for proper analytical eqUIpment to perform to hIgher
standards In a short time.
The CHP plant management gathers detailed informatIOn and performance data
on all aspects of the equipment operatIOn and maintenance. Therefore, data on
gas and mazut fuel consumption, gross and net KW output, steam and hot water
(gcal heat) for monthly (heating periods) and annual baSIS IS eaSIly obtained.
• The statIOn has carned out refurbIshment and development work m the past
