CONCLUSIONS AND RECOMMENDATIONS
2. RECOMMENDAT IONS (CONTD)
(2) Tube out a preheater bundle with CDA 194 to expose the alloy
to tube velocities between 7 and 10 feet per second on the
brine side.
(3) Use CDA 194 alloy evaporator tubes in one of the high-temperature
effects.
(4) Install stainless steel test spools in hot brine piping exposed
to considerable turbulence.
(5) Put cement liners in high-temperature effects.
D. Improved Level of Precision of Data Gathering Equipment
(1) Replace main plant input and output fluid orifice meters with
turbine meters.
(2) Discard all existing high-accuracy thermocouples. Carefully
and selectively reinstrument the entire plant with precision
grade platinum-resistance thermometers. The temperature measuring
elements should be positioned in the effect steam chest rather
than the steam transfer line. Attempts to measure brine tempera-
ture at the top and bottom of tube should be discarded. At least
one effect should be instrumented in such a way as to determine
the temperature profile in the steam chest.
(3) Obtain the equipment necessary to enable the keeping of the temper-
ature sensing elements in proper calibration.
(4) Discard the absolute pressure manometers. Relocate the differen-
tial pressure manometer systems to the top deck so as to minimize
problems with liquid in impulse lines.
(5) Defer any further work on the data logger until the new instru-
mentation is installed, calibrated, and proved out.
E. Staff the Plant to Accomplish the Development Engineering Objectives
in the Field
(1) Provide the Development Engineer with field process engineering
help.
(2) Provide the Development Engineer with the services of technicians
for the purpose of data gathering and routine calculations.-90-
