This presentation discusses the utilization of waste heat. It begins with an introduction that defines waste heat and describes it as a green energy source. The purpose is then stated as providing information on waste heat recovery advantages and identifying potential waste heat sources and applications. Sources of waste heat are listed as power generation, industrial processes, electronics, and biological. Advantages include direct and indirect benefits. Applications of waste heat utilization include agriculture, aquaculture, power generation, and sea water desalination. The conclusion emphasizes that waste heat is currently being wasted but can be used for other purposes, with the strategy depending on temperature and economics.

3. Introduction
waste heat can be defined as any source
of rejected heat that has a portion to
be recovered and re-used economically.
Utilization of waste heat is being
described as a green and carbon neutral
energy source

4. Purpose
To give the information
Advantages of waste heat recovery
To identify the potential recoverable
waste heat sources and applicable areas
of utilization

5. SOURCES OF WASTE HEAT
Power generation
Industrial process
Electronics
Biological

6. ADVANTAGES OF WASTE
HEAT RECOVERY
1. Direct benefit
2. Indirect benefit

7. UTILIZATION OF WASTE
HEAT
Agriculture
Aquaculture
Power generation
Sea water desalination

8. Conclusion
• Till now heat is being wasted as a by product
• Waste heat can be used in other purpose
• The strategy of how to recover this heat
depends in part on the temperature of the
waste heat gases and the economics involved
• Utilization of waste heat is becoming more
important with climate change
