日本三菱石油化工有限公司与神户制钢所联合研究开发的一种螺旋式膨胀动力回收装置,成功地投入生产使用。据报道,这种高效能的节能设施具有划时代的重要意义,目前处于全世界领先的行列。此装置用于回收高压蒸汽设备在减压释放时的蒸汽能量,为别的设备(如发电机等)提供动力,其工作热效率为70％左右。过去,一般采用汽轮机装置回收上述 Japan’s Mitsubishi Petrochemical Co., Ltd. and Kobe Steel joint research and development of a spiral expansion power recovery unit, successfully put into production. It is reported that this high-performance energy-saving facilities have epoch-making significance and are currently leading the world. This device is used to recover the steam energy of the high-pressure steam equipment at the time of decompression and release, and to power other equipment (such as a generator). The thermal efficiency of the device is about 70%. In the past, steam turbine plants were generally used to recover the above
