ADVANCED STEAM TURBINE POWER PLANT TECHNOLOGIES AND THE MATERIALS IMPLICATIONS
Assuming the background of a relatively conventional scenario of steadily rising energy costs and increasing environmental constraints, steam turbine cycles employing primary and reheat temperatures in the range of 750 to 800 degrees C at pressures of 500 to 600 bar appear to be reasonable to strive for as thermal efficiency gains of at least 5% may be realized. In terms of feasible cost increases of plant both with respect to invested per kWh and tolerance limits for R & D money expendable over a period of about 10 years, R & D towards this goal seems interesting. Before starting out on a conscious effort in "materials and technologies for post-next-step steam power plant" (the "next step" is currently well underway on a national effort basis at least in two economic world regions: USA and Japan), another 3- year period of more detailed preparatory studies seems appropriate. This may mean entering looking for new materials technologies or switching from one to another class of materials processing or, in effect, taking on new processing sequences ("technology mix") not heretofore practized. The advent of CAD-CAM makes computer simulation and modelling an important partner of this R & D effort.
