WebIn most designs, the reaction of the turbine varies from hub to shroud. The hub is close to an impulse turbine. The impulse turbine is a reaction turbine with a reaction of zero (R = 0). The shroud is usually above a reaction of 50%. The utilization factor for a fixed nozzle angle will increase as the reaction approaches 100%. WebThere are three methods of compounding of steam turbine: Method # 1. Velocity-Compounded Impulse Turbine: This type of turbine consists of a nozzle or sets of nozzles and a wheel fitted with two or more rows of moving blades.

WebIn impulse turbines, the steam expands through the nozzle, where most of the pressure potential energy is converted to kinetic energy. The high-velocity steam from fixed nozzles impacts the blades changes its direction, which in turn applies a force.The resulting impulse drives the blades forward, causing the rotor to turn. The main feature of these turbines is … WebCompounding of steam turbines is the strategy in which energy from the steam is extracted in a number of stages rather than a single stage in a turbine. A compounded steam turbine has multiple stages e.g it has more than one set of nozzles and rotors. These are arranged in series either keyed to the common shaft or fixed to the casing.
