REPOWERING OF WASTE HEAT USING ORC IN SLOVENIA
KOMUNALNA ENERGETIKA / POWER ENGINERING, 6
The article deals with ORC (Organic Rankine Cycle) process. This is a working cycle for
conversion of low temperature heat into mechanical work. The working fluid is an organic
refrigerant. Due to specific properties of refrigerant also the ORC process has some
peculiarities. The article presents the ORC process, which will be applied in the Slovenian
industry providing a generator power of 120 kW. Some specific features of ORC processes
are addressed and the impact of implementation of heat exchangers is analysed. Analysis of
the impact of cooling water temperature on the operation of ORC process is also provided.

SYSTEM FOR WASTE HEAT RECOVERY FROM COMPRESSORS
KOMUNALNA ENERGETIKA / POWER ENGINERING, 11
In the group Talum heating of production and business premises and sanitary water is largely carried out by steam, bought from the company Silkem. Produced at our gas boiler, steam is conducted to individual heating stations throughout the facilities in the above-ground and underground steam lines. In the substations heat from steam is via the heat exchanger handed over to hot water, which then through the radiators, fan-heaters and floor heating emits its energy to the premises, and heats sanitary water in boilers. The condensate is in the vast majority returned back to the company Silkem.
