were starting a bOiler, 370°C, 40 kg/cm 2 and saw there was a problem, valve was<br />
steaming, not normal They measured insulation temperature difference near the valve<br />
and found a 10 cm crack on weld of 325 x 24 mm pipe<br />
We went to the power plant control room to look at the Instromet Encal gas chromatograph<br />
(GC) display mounted In the main panel Above It IS mounted a data logger which can<br />
Input real time heat content from the GC to record total from metered gas flow At present,<br />
they Input a fixed value of KCal/cu m.<br />
We then went to the gas metering substation to see the GC installation They ran new<br />
shielded cable about 3000 ft from GC to control room display control Unit They took a<br />
sample line from downstream of Orifice meter run to control house where GC IS mounted<br />
on the wall They added a filter In the sample line with SIlica gel dlsslcant for removing<br />
mOisture and crude from gas sample All tubing and wIring IS Installed, waiting for<br />
calibration gases to clear customs In Kiev, so the startup engineer can travel to<br />
commiSSion the GC. Their biggest concern IS the need for a spare electrOniCs display<br />
board Attached IS a diagram of the system<br />
We went to look at the installation of oxygen analyzers on one of the two large hot water<br />
heating bOilers The electroniC two-channel analyzer display Unit was mounted In the bOIler<br />
control panel They mounted the probes below the observation ports on backpass of the<br />
boilers They made up an extra pair of flange-nozzles and Installed them In the second<br />
bOiler so the probes could be SWitched to that bOIler when operating.<br />
They mounted the reference air control panel between the two boilers with cable and<br />
copper air tubing run to both They found a very small air blower-compressor salvaged<br />
from an old hydrogen analyzer, which they mounted inside the cabinet<br />
We were prOVided with a table of consumption, heating values and prices for natural gas<br />
and mazut for 1996-1997, attached In-plant cost to produce electriCity IS 5 3 Kp/KWh<br />
(2 91 ¢/KWh), and Kremenergo sells at 711 Kp/KWh (3 91¢/KWh)<br />
