HFC-245fa ORC UNITS IMPROVE COGENERATION GAS TURBINES ENERGY EFFICIENCY IN SLOVAKIA

Ten new Organic Rankine Cycle (ORC) generators using HFC-245fa as working fluid have been installed in a Slovakian district heating plant to increase the on-site efficiency of two cogeneration gas turbines.

The turbines produce steam and warm water to feed the town’s district heating network, and the remaining lower temperature exhaust gases, that would otherwise be released to the atmosphere, are handled by ten 50 kW machines, generating low cost electric power and improving the efficiency of the whole system.

The Slovakian plant is the first in Europe to use ORC units to improve combined cycle gas turbines efficiency by recovering energy from low temperature (77-116 C) waste gases.
