KALINA CYCLE SYSTEM FOR POWER GENERATION USING GEOTHERMAL ENERGY

摘要

The present invention relates to a Kalina cycle system for geothermal power generation, and more specifically, to a Kalina cycle system for geothermal power generation, which can improve reliability and safety of components of a geothermal power generation system. The Kalina cycle system for geothermal power generation according to the present invention comprises: an evaporator (10) configured to vaporize mixed working fluid introduced inside by making heat exchange with high-temperature geothermal water; a primary separator (20) configured to primarily separate a liquid-phase mixture from the gas-phase mixture of the mixed working fluid passed through the evaporator (10); a turbine (40) configured to make the gas-phase mixture passed through the primary separator (20) introduced thereinto; a recycler (30) configured to be supplied with the liquid-phase mixture; a mixer (50) configured to uniformly mix the gas-phase mixture discharged from the turbine (40) with the liquid-phase mixture separated from the primary separator (20) and then passed through the recycler (30); a condenser (60) configured to liquefy the mixed working fluid passed through the mixer (50) by making heat exchange with low-temperature geothermal water and then to supply the liquefied mixed working fluid to the recycler (30); and a secondary separator (80) interposed between a gas-phase mixture outlet of the primary separator (20) and an inlet of the turbine (40) and configured to secondarily separate a remaining liquid-phase mixture, wherein the mixed working fluid consists of ammonia and water.
