Waste Heat Recovery

Based on a system that generates electricity from Waste Heat, ORC (Organic Rankine Cycle) technology uses the heat from the hot source to evaporate the organic working fluid inside the evaporator. The working fluid of choice can be silicone-based fluids, or hydrocarbon or coolant-based fluids can be used for low temperatures. Pressurized steam is then sent to the turbines and combined with the generator to generate electricity. The steam is condensed back to a liquid state in the condenser. Here, either a cooling tower, groundwater or river water is used as a means of cooling. The air cooling system can also be used as an alternative. The refrigerant pump then pumps the working fluid back to the evaporator and this closed loop process repeats. Since it is used as a hot liquid fuel source, the fuel cost is zero. Also, since no combustion takes place, there is no emission to the atmosphere in the ORC energy system.

Hot springs are usually hot liquid or gaseous. Heat from such sources is transferred directly or indirectly to the ORC working fluid by means of an intermediary device, depending on the characteristics of the waste heat source or other limitations. Liquid waste heat sources are often combined directly with the ORC unit. Gaseous heat sources are combined indirectly.

As Akterm Group, we are instrumental in bringing this technology to our country by making a distributorship agreement with Triogen ORC, which has proven itself in the field of energy production from waste heat in the world and has signed many important projects.
