<p>PURPOSE: A cogeneration system using a low pressure turbine is provided to reduce the costs for electricity generation by directly using solar energy or thermal energy. CONSTITUTION: A cogeneration system using a low pressure turbine comprises a first working fluid circulating unit which transfers working fluid heated by solar energy, geothermal energy, waste heat, and waste water heat from a high-temperature working fluid circulating part to a low-temperature circulating part, a coolant circulating unit which transfers coolant from a low-temperature coolant circulating part(20a) to a high-temperature coolant circulating part(20b) for heat exchange with the working fluid circulating unit, a first heat exchanger(30) which evaporates coolant through heat exchange between the working fluid circulating unit and the coolant circulating unit, a low pressure turbine(50) which is driven by the coolant evaporated by the first heat exchanger, a second heat exchanger(40) which liquefies the gas coolant discharged from the low pressure turbine into the liquid coolant, a storage tank(60) which stores the liquid coolant transferred from the second heat exchanger, and a pump(70) which transfers the coolant from the storage tank.</p> |
