Heat Energy Recovery System

UJJAWAL KOHLI, Vaibhav Mishra, Sparsh Singh Kotwal


Energy demands in today’s world have increased and the main area of concerns is that approximately 90% of world’s oil reserves are expected to be depleted within two generations. We are trying to build a technological system where the by-product of conventional fuel i.e., exhaust heat of fuel, will be converted into another form so that it can further be used again. Mainly, recovery of heat energy is our prime motive. According to our motive, we are going to recover the heat of the hot exhaust gases from chimneys of factories which usually dissipate into the atmosphere and thus that exhaust heat left unused. So, we are making a water storing tank i.e., water jacket that will surround the chimney through which heat from hot exhaust gases will come in contact with water present in water jacket. Through the process of conduction, heat transfer will take place. Therefore, due to heat, the temperature of the water will increase to a very high extent, and hot water can be used in boilers as a pre-heater for household or commercial purposes. Furthermore, global warming will also be controlled if we start implementing this technology at a huge scale.
