Below is a sketch of a typical coal power plant.
The highlighted portion within the red border is replaced with the new Patent Pending Powerdyne Technology. i.e. all equipment from the coal feed pulverizer up to the turbine are replaced with new the Powerdyne system.
On a retrofit, the existing plant is not shut down for the retrofit. The retrofit is built adjacent to the old plant and valved into the steam feed prior to the turbine.
