With the exhaust nozzle pointed at the sky, the engine will be placed near the smokestack and turned on.
As the engine roars to life, it will generate a nozzle speed of 400 metres per second (1,440km/h; 900mph), which is more or less the speed of sound.
The exhaust will create powerful updrafts that will, to put it simply, blast the emissions from the plant to higher altitudes, above a meteorological phenomenon called temperature inversion, where a layer of cold air is held in place by a warmer "lid" trapping smog.
The jet exhaust will act as a "virtual chimney", drawing in and transporting the smog, which makes Delhi's air some of the most toxic in the world. A single jet engine can deal with emissions from a 1,000 megawatt power plant.
