Feb. 26 Through March 1 - In Krivoi Rog Power Plant
On Feb. 27, we brought the equipment to the power plant and set it up in the archIves library.
We then went to meet the Director Valeny Chebotar and the Chief Engineer Vladlmer Ludekof
and gave a brief introduction and description of the Instruments we brought for them and
presentation of our scope of work. The Director gave a description of the power plant. The
Director and Chief Engineer then came with us to the library to look at the instruments. They
then called for specialists to come meet WIth us.
We first met with Vadim Necrasov, Chief of water treatment and chemIcal laboratory and
Svetlana Kikolionkova, Engineer - chemIcal laboratory. We discussed bOller water chemIStry
and fuel analyses and requested data on coal, mazut and natural gas.The most cnttcal need IS
for online monitonng of oxygen in feedwater and SIlica (Si0:J after the demIneralizer for
makeup to the condensers. Each unit has a condensate polisher. They also expressed a cnttcal
need for an online natural gas calorimeter measunng Kca1/Kg and Sp.G. and a laboratory
calorimeter for measuring coal and mazut heating value in Kcal/Kg.
We were then introduced to the boiler engineers and electrical engineers who would be
responsible for the instruments we brought.
We demonstrated the functions and operation of the Enerac and let the two assigned engineers
practice using the instrument. We were given monthly data for 1994 consumptIOn and pnces
of coal, gas and mazut.
HHV ofTP coal, mazut and Russian natural gas was calculated and programmed into the Enerac
with the Texas Instrument computer. We then went to No.5 block nght boiler (TPP-21OA) to
take some tests. We tried to get a sample at the convection backpass (about elev. 26000) where
the existing oxygen analyzer extr3Ction point IS located. This locatton is between the backpass
and furnace above the three back burners. The engineer tned to insert the probe lOto a sample
port, but it hit something and would not go through.
We went back to No.5 unit and took four good tests, one each through the center thermocouple
insertion point ahead of each regenerative air heater.
During dinner meeting, Dr. Osborne (USAID) asked why the CIS has not used Enerac type
analyzer before, to the Director and Chief Engineer. They explained that the former SOVIet
Union did not have the advanced manufactunng capabilities to make this kind of computenzed
analyzer. We explained that it is only in the past few years that the state-of-the-art
electrochemIcal specific gas sensors have been developed In the U.S. and Europe and that the
Enerac is presently the most advanced U.S. made analyzer which is computer programmable.
Up to this time the Orsat flue gas analyzer has been the most accurate method for testmg flue
gas composition by volume for CO, O 2 , CO 2 , and N 2 by difference. The dIsadvantage In It's
