GT-ORC Organic Rankine Cycle System
Convert low- and medium-temperature heat from hot water, steam, exhaust gas, or industrial processes into useful electricity.
40-1,000 kW ORC Power Generation Portfolio
The GT-ORC system converts low- and medium-temperature waste heat into electricity through an Organic Rankine Cycle. A sealed working fluid absorbs heat, drives the generator, condenses, and recirculates continuously. Its closed-loop design provides stable performance, easy maintenance, and a long service life.
ORC Power Generation Process
- Fluid Pressurization: The pump pressurizes the low-pressure working fluid and delivers it to the evaporator.
- Heat Absorption: The fluid absorbs heat in the evaporator and enters the expander-generator as vapour.
- Power Generation: The high-pressure vapour drives the expander-generator to produce electricity.
- Condensation and Recirculation: The vapour releases heat, returns to a liquid state, and re-enters the pump to repeat the cycle.

- Working Fluid Pressurization
The pump increases the pressure of the liquid working fluid and delivers it to the evaporator. - Heat Absorption and Evaporation
The fluid absorbs heat from the available heat source, becomes vapour, and enters the expander-generator. - Expansion and Power Generation
The high-pressure vapour expands through the expander and drives the generator to produce electricity. - Condensation and Recirculation
The vapour releases heat in the condenser, returns to liquid form, and re-enters the pump to repeat the cycle.
