Abstract:

A test was run after incorporation of burner modifications to check the effects of these modifications. Since the heated water supply used previously was not available for this test, tap water at 50 5F was used in the water cooled copper plates. The hot core temperature was lowered approximately 90F to give a temperature difference across the generator approximately equal to that expected during hot day operation with 95F sea water. This lowering of the temperature range results in a slightly higher output from the low temperature thermoelectric modules. This is caused by a higher thermoelectric material efficiency in this lower temperature range. Under these conditions the power output was 119.8 watts at 24 volts. The open circuit voltage was 49.6 volts. Correcting for the higher thermoelectric material efficiency gives a predicted output of 111.8 volts at 24 volts and an open circuit voltage of 48.5 volts. The waste heat sink to be mounted in the hull of the buoy was redesigned.
