Webimpulse turbine just strikes on single ring of rotor that cause wastage of steam ranges 10% to 12%. To overcome the wastage of steam compounding of steam turbine is used. Types of compounding In an Impulse steam turbine compounding can be achieved in the following three ways: a. ... the steam velocity is lower than of the previous case. 3 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%.

WebAdvantages velocity compounded steam turbine: 1.This arrangement needs small space. 2. This is very reliable and easy to operate. 3.Initial cost is low for this arrangement. 4. Since nozzle's steam is considerable, the turbine does not need to work in high pressure and turbines structure need not be very strong. WebComputer Science. Computer Networks.
