This invention is related to the usage of waste energy in flue or exhaust gases to produce electricity. in internal combustion engine, the exhaust gases possess some kinetic energy, which discharge waste in environment. so,by using the turbocharger, this kinetic energy will be used for producing electricity by means of turbocharger and alternator. in thermal power plant, flue gases have kinetic energy which is waste in environment. so. using turbocharger this kinetic energy will use for produce electricity by means of turbocharger and alternator. the turbocharger is put between the forced draft fan and inlet of chimney. forced draft fan sucks the flue gases from the plant and release them into the turbocharger inlet. this flue gases have some kinetic energy. by using kinetic energy, the turbocharger is rotated and it converts kinetic energy into mechanical energy. the alternator is connected to the turbocharger, which converts mechanical energy into electrical energy. this conceptual equipment is eco-friendly. it decreases air pollution, caused by exhausting gases. it runs with waste energy. so, input expenditure of raw material can be neglected. only installation of turbocharger and bypass way expenditure is needed.
