The main problem remaining with utilizing wet
steam with screw expanders therefore lies only with
the large size of machine needed to expand to
low condensing temperatures.However,this can be
largely overcome by raising the condensing temperature
to approximately 100 ◦C or more.At this
value,the vapour pressure of steam is just over
1 bar and,although less than that of the most commonly
used refrigerants and hydrocarbon working
fluids at the same temperature,is of comparable
value.
