The restarting injector is the proven power supply for steam generators.
It is a mechanical device whose operation, characterized by being independent of electrical energy, is based on fluid dynamics principles that relate the velocity and pressure of a fluid.
It uses the steam from the generator itself as the motive fluid, transforming its kinetic energy into pressure energy capable of sending feedwater to the boiler. The steam used to operate the injector then condenses and returns to the generator.
It operates within very wide pressure ranges with significant hourly flow rates.
