   ocr: 4) High etticiency is possibie, but at the expense of much greater complesity in the boiler, particulariy the boiler controis. It is also difticult to design cost ettective boilers which will withstand the high temperatures (for efficiency) and pressures (for small size) required. 5) - Iti is interesting to note that many electric generating powerplants use the steam turbine cycle, which is limited in its efficiency in the same ways as the reciprocating steam engine. However, by using very high temperatures and a more sophisticated steam cycle, they achieve very high etticiencies, on the order ...
