Waste heat recovery from exhaust gases of a Diesel engine generator and its effects on emissions

M. Tech. Engineering Technology .Demonstrates through design and experiments the heat transfer effectiveness of energy recovery from waste gases by using a heat exchanger. To use the heat exchanger to intercept the waste gases before they leave the process, extract some of the heat in the gases and use the same for preheating/heating the process water. The experiment is also intended to demonstrate whether or not waste heat unit has an effect on the emissions released to the environment. Diesel engines have been widely used in heavy-duty vehicles for their better fuel efficiency and higher power output than gasoline engines. However, the emissions of gas (CO, HC and NOx) and particulate matter (PM) pollutants from the diesel engine receive much concern from the general public and environmental researchers because of the epidemiological and toxicological investigations suggesting a relationship between exhaust pollutants exposure and adverse health effects
