existing oxygen analyzers on power steam boller 5 - left Side. The bOIlers were burning natural
gas. We took two samples on the left side, then took one sample on the right side and got off
the boiler when the reading showed carbon monoxide went over range with excess aIr reading
moving between°and 2 percent. We were informed that the FD fan on the right Side was not
operatIng because of breakdown. The plant immediately reduced load on this boller.
We ran three tests on the left side ofboiler No.7. The combustion efficiency was fair but could
be improved by reducing excess air.
We continued our discussions With the engineers requestmg mformanon and data required for
our audit report and planning our work for Monday.
On Feb. 20, we met with the Chief of the laboratory, Antomna Ogorodnikova to gather data and
information on natural gas and mazut. We obtaIned test data for 1994 giving monthly average,
maximum and minimum heat contents in KJoules/Nm 3 and Kcal/Nm 3 with total gas consumpnon
by month in million Nm 3 and corresponding pricmg. It appears that Odessaenergo IS being sold
short by an average 115 Kcal/Nm 3 by Gasprom. This IS why they place such a high pnonty m
obtaimng an online recording calorimeter to prove the delivery of gas.
We went to the offsite hot water peaker bOIlers (3) and steam bOIlers (2) to look at locatIOns to
put in-situ oxygen probes and locate flow meters for mazut and get measurements. the assigned
engineers were also made familiar with the operation of "Heat Spy" and Fluke harmomc
analyzer.
Past noon we took the combustion analyzer to get more test data on boilers No.5 and 7, except
this time at the LD. fans. One test was made on each side of boiler No.7. The oxygen and
excess air readings were very high, partly due to air leakage from the air heaters. We discussed
the readings with the Chief Engineer of the power plant Oleg Yarotskiy and boiler expert from
Odessaenergo Nicolai Marenkov. They agreed to make a slight adjustment to reduce excess aIr
to tune the boiler and we took additional readings. The results were sigmficant, provmg to the
engineers the value of thiS Instrument for saying fuel.
We returned to the Director's office to gather the remammg information from the plant. We
were given copies of boiler control diagrams, dimenSIOns for cable runs for oxygen analyzers,
etc. We also were given a letter of receipt for the equipment given to them. The engineers will
provide additional test runs for our use.
1.3.3 Tuesday. Feb. 21. 1995 - Travel to Krymenergo - Simferopol CHP Plant
Feb. 21 through Feb. 24 - In Simferopol CHP Plant
On Feb. 21 evening we arrived at the power plant. The plant Director Alexander Chupnnko
and Deputy Director Oleg greeted us. He gave a bnef descnpnon of the power plant. Andryl
Kononov and Vitali Plotnikov met us and made mtroductlOns.
