WebAxial flow reaction turbines: If water flows parallel to the axis of the rotation of the shaft, the turbine is known as axial flow turbine. When the head at inlet of turbine is the sum of P.E. and K.E. and during the flow through a part of P.E. is converted into K.E. the turbine known as reaction turbine. WebHence a number of stages vary as per applications. Step 1:-. The high-pressure and superheated steam is first passed through the ring of nozzles where high-pressure steam is converted into higher velocity steam and it also gives direction to the flow of steam. Step 2:-. high school sports player banners

WebThis type of a velocity diagram is considered to have zero-exit swirl. Figure 9-8 shows the various velocity diagrams as a function of the work factor and the turbine type. This diagram shows that zero-exit swirl can exist for any type of turbine. Sign in to download full-size image Figure 9-8. As explained earlier a reaction turbine is one in which there is pressure and velocity loss in the moving blades. The moving blades have a converging steam nozzle. Hence when the steam passes over the fixed blades, it expands with decrease in steam pressure and increase in kinetic energy. This type of turbine has a number of rings of moving blades attached to the rot…
