Abstract

A hot-water storage type power generating unit includes a first tank coupled to a power generating system having a generator, a hot water producting unit for heating medium-temperature water from the first tank with exhaust heat from external equipment to produce high-temperature water, and a second tank for storing the high-temperature water from the hot water producing unit. The high-temperature water is supplied from the second tank to the power generating system for generating electric power to meet peak load demands. The power generating system includes a rotary separator turbine rotatable by the high-temperature water from the second tank for separating steam from the high-temperature water, and a steam turbine rotatable by the steam from the rotary separator turbine, the generator being operatively coupled with the steam turbine for being rotated thereby.
