g) Makeup water temperature.
h) Makeup water flow.
i) Blowdown temperature.
j) Blowdown flow.
As a result of calculations, the cooling tower capability can be
quantified as a percent of design.
19.1.2.5 Evaporators. Evaporators shall be tested in accordance with ASME Performance
Test Code, PTC 14, Evaporating Apparatus.
a) The following are the major measurements which must be made.
1) Evaporator feedwater flow.
2) Evaporator feedwater temperature.
3) Evaporator vapor sample.
4) Evaporator vapor pressure.
5) Evaporator vapor temperature.
6) Steam supply pressure.
7) Steam supply temperature.
b) As a result of tests and determinations based on PTC 14 methods, the
following performance parameters can be quantified.
1) Maximum capacity.
2) Total solids in vapor.
19.1.2.6 Deaerators. Deaerators shall be tested in accordance with Performance Test
Code, PTC 12.3, Deaerators. ASME PTC 12.3 Part II describes several methods of
determining the dissolved oxygen content in deaerated water. These methods include the
titration method and the colorimetric method. Continuous oxygen analyzers are also
commercially available.
19.1.2.7 Pumps. Centrifugal pumps shall be tested in accordance with ASME Performance
Test Code, PTC 8.2, Centrifugal Pumps.
a) The following are the major measurements which must be made for each
pump.
1) Inlet flow.
2) Inlet temperature.
3) Inlet pressure.
