Energy Saving Industrial Rankine Cycle Power Plant For Waste Hot Water

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 waste heat recovery from hot water

In many industries, a lot of waste hot water will be generated from the processes. Part of hot water can be used for other processes which need to be warmed or heated. However there is still a tremendous amount of hot water to be discharged directly.

An ORC system are normally arranged to recover the waste heat containing in hot water to generate electric power, which contributes to energy-saving and environmental protection.
