The working principle of an impulse turbine involves converting the kinetic energy of steam into mechanical energy. High-pressure steam is directed through nozzles, accelerating the steam before it strikes the turbine blades, causing the rotor to spin. The expansion of steam through the nozzles generates the impulse needed to turn the turbine. Small steam turbine manufacturers like NCON Turbines design efficient impulse turbines to deliver reliable power generation solutions, especially for smaller energy systems.
