ECO-06 MAZUT SONIC FLOW METERS
The audit team learned through intervIews with station personnel that one area whIch has
hampered the stations progress m energy Improvements IS the mabilIty to accurately measure the
decrease m fuel consumption due to any changes in operation or equipment motivated by
efficiency improvement ThIS is because the eXIsting fuel flow mstruments in place at the statIon
are maccurate or don't work. If only modest gams m effiCIency could be realIzed due to the
mcentIve proVIded by the abIlIty to more accurately evaluate such Improvements, such flow
momtonng equipment could pay for Itself m a very short penod.
Lme sizes and design informatIOn were obtained for speCIfying somc flow meters for two supply
and two return mazut lines serving the boilers.
ECO-07 ON-LINE NATURAL GAS CALORIMETER
The most important concern and pnonty at Burshtyn was the urgent need for analytical
instruments for momtonng fuel qUalIty (coal, mazut, gas). The data mdIcates that the plants are
paying large sums of money for fuel energy content (heatmg value) whIch they do not receIve.
Instruments for measuring the fuel heat value m Kcal/Kg and other parameters would prOVIde
the documentation necessary for making claIms agaInst suppliers.
They urgently need an on-Ime gas calorimeter to verify the heat content supplIed by Gasprom.
Their laboratory calorimeter is not commercial (certified), the tests are not contmuous so they
cannot make a claim for credIts. We were given test results for monthly averages for 1994, as
well as gas consumption. The plant claims losses of about 1.905 X 10 10 Kcal (7.559 X 10 10
BTU's) which results in $159,000 loss per year. Although thIS loss of expenSIve gas fuel
heatmg value has nothmg dIrectly to do WIth "combustIOn" efficiency, this IS also a pnority m
reducing the large sums of hard currency they must pay for fuel gas.
ECO-08 COAL FLOW METER
The audIt team learned through mterviews WIth plant personnel that one area WhICh has
hampered the plant progress in energy improvements IS the mabilIty to accurately measure the
decrease In fuel consumption due to any changes m operatIOn or eqUIpment motivated by
efficiency Improvements. This is because the plant does not have instruments to measure the
fuel flow for eIther mazut and coal to each boiler. Natural gas flow meters already exist per
each bOIler and work well. If only modest gaIns m effiCIency could be realized due to the
mcenhve prOVIded by the abIlIty to more accurately evaluate such Improvements, such flow
momtonng eqUIpment could pay to Itself m a short period of hme. Instruments to measure raw
coal consumption to 200 MW Umt #4 on belt conveyors, located between raw coal bunkers and
mills (coal feeder) are recommended.
For detailed calculations see Appendix A-I.
