日本中部电力公司为了提高火电站的热效率,与日立制作所、东芝和三菱重工三家公司共同从事开发采用钛合金材料的40英寸汽轮机叶片。目前这三家公司均已完成了叶片的制造,正在进行各种分析,将在1987年2月在实际运行条件下进行旋转负荷试验。这项研究开发工作预定在1987年3月结束,汽轮机的长叶片采用钛合金,这在世界上还是第一次。据称,如果能提供实用,则热效率比最新型的火电机组约提高1.5％(相对值),而且每台机组每年可节省燃料费2～3
Japan Central Electric Power Company and Hitachi, Toshiba and Mitsubishi Heavy Industries to co-operate in the development of 40-inch turbine blades using titanium alloy materials in order to improve the thermal efficiency of thermal power plants. At present, all three companies have completed the manufacture of blades and are conducting various analyzes and will carry out the rotation load test under the actual operating conditions in February 1987. This research and development work is scheduled to end in March 1987 and the turbine’s long blade is made of titanium alloy, the first of its kind in the world. Allegedly, if practical, the thermal efficiency is about 1.5% (relative) higher than that of the latest thermal power unit, and each unit can save 2 to 3 fuel costs per year
