Energy Conservation by Waste Heat Recovery Methods
As per the first law of thermodynamics, 100% energy utilization is prohibited. Thus, some utilized energy always becomes waste heat, and is normally discharged into the environment. Many energy applications in various industries have faced the same situation. Utilizing the waste heat for other purposes is sustainable utilizing. Examples of the waste heat recovery system are described below.
• Vented steam WHR (Waste Heat Recovery): In the sterilization process or retorts, most steam is vented to the atmosphere after the process is ended. But the vented steam still remains a potential source of heat energy. The potential heat energy can be
used for hot water production feeding to a boiler or other process.
