Experimental Analysis of Thermoelectric Waste Heat Recovery System Retrofitted to Two Stroke Petrol Engine

摘要

The efficiency of the thermal power plants is only around 35% and the remaining 50 - 55% of energy is lost due to many losses. The major source of loss in the conversion process is the heat rejected to the surroundings due to the many inherent constraints. Also further losses of around 10-15% are associated with the transmission and distribution of electricity in the electrical grid. Therefore, the energy saving is one of the key issues, not only from the view point of fuel consumption but also for the protection of environment. So, it is imperative that significant efforts have been made for conserving the energy by recovering the heat dissipated to the atmosphere. The main objective of this paper is to study and analyse the feasibility of retrofitting the waste heat recovery system to a two stroke petrol engine. Finally, the potential of recovery of waste heat as a renewable energy source is assessed.
