•
• The station has had sIgnificant cracking in the inlet nozzle belt area of the
turbines and they have replaced the existmg umt 12 HP and IP shells and
modified steam path blading for the new uprated 225 MW machmes offered by
the turbine manufacturer.
• Each condenser is cleaned twice per year. At the time of condenser cleanmg,
there IS a loss of condenser vacuum WhICh causes a 5 MW loss m generator
output.
• The Ion exchange resms m the demmerahzer are m such a poor conditlOn that
excessive amount of water, aCId and caustIc are consumed for regeneration whIch
adds to pollution.
• The chemlCallaboratory ungently needs modern analytical equipment.
• Power plant design work is being done by Ukrame Teploelectroproject, L'VIV
Research Institute and TransmisslOn desIgn IS being done by Electrosetproject m
L'VIV.
4.0 DESCRIPTION OF AUDIT ACTIVITIES
The audit activities mcluded the collectlOn of mformatlOn and data from vanous reference
sources and indivIduals working withm the power plant. The activitIes are of two types: one
for specIfic combustion efficiency audIt measurements and calculatIons, and the other for
information of a general natural regarding other energy conservation measures.
4.1 Specific Audit Activities
4.1.1 Scope and Methodology
Individual systems and/or eqmpment were IdentIfied for data collectlOn and analySIS and were
selected based on several cntena, includmg:
• Quantity of energy used withm the system.
• PotentIal for energy effiCIency Improvements.
• Significance of system/component to the power plant.
• PotentIal for replIcation.
The selectIon of systems and eqmpment to audit were made after meetmg WIth power plant
specialIsts to dISCUSS energy conservatIon prionties and a walk through the power plant. In
preparatIOn for the audIt actIvitIes at the power plant, techmcal energy momtonng eqUIpment
was purchased m the United States, ShIpped to Kiev and delIvered to the power plant. The
equipment was purchased to momtor and to make measurements of various systems that were
likely to be encountered WIthin the power plant. The measurements enabled auditors to learn
specIfic informatlOn about the systems bemg investigated. Based on the measurements, the
auditors calculated boiler effiCIency and potentIal energy improvements that could be gamed by
mstallmg energy effiCIency eqmpment. Economic paybacks were calculated and the pnonty of
Items estabhshed accordmg to the shortest payback. Based on estImated cost of eqmpment and
