Professional Organic Rankine Cycle System For Waste Heat Recovery

Principle of ORC system

• The low boiling point organic working fluid makes heat exchange with the heat source through evaporator, then absorbs heat and is evaporated to high temperature & high pressure steam.
• The high temperature & high pressure steam drives the turbine expander & generator set for electric power generation.
• The temperature and pressure of organic steam is decreased after work.
• The organic steam with low temperature & pressure flows into the cooling system to be condensed to fluid.
• The organic working fluid is pressurized by the fluid pump for next cycle.

ORC system for waste heat recovery from kiln in cement plant

* The temperature of flue gas after its direct utilization for other process will be at approximately 250°C-350°C.

* ORC system can recover this medium-low grade waste heat for electric power generation.

* By means of gas-oil heat exchanger (heat conducting oil stove), the heat conductive oil can absorb the heat containing in flue gas. The hot oil is directed to ORC system for power generation.

* Rated power: 1 – 6.5 MW
