Abstract
The influence of noncondensables on the output work from geothermal steam power plants was studied. Two problems were addressed: the effect of CO/sub 2/ on the exergy (available work) of a given mixture of steam and CO/sub 2/ and secondly, the effect of CO/sub 2/ on the expansion work of an ideal turbine exhausting at a given back pressure. The results in the latter case were modified to account for the influence of CO/sub 2/ on the dryness of the exhaust mixture and the corresponding effect on the expansion efficiency.
