Francis turbine is a kind of counter-turbine turbine, invented by American engineer Francis in 1849, also known as Francis turbine. The water flows into the runner radially from all around, and then flows out of the runner approximately axially. The runner is composed of an upper crown, a lower ring and blades. The development trends in recent years are high head, large capacity, high specific speed and high efficiency.
Francis turbine is suitable for the range of water head from 20m to 700m, the mechanism is compact and simple, the operation is stable, and the efficiency is high. It is one of the types of water turbines widely used in countries around the world. The output of a single machine ranges from tens of kilowatts to hundreds of thousands of kilowatts.
Horizontal Francis turbine unit, with horizontal shaft, could be 2 or three supports. Which is normally one stair arrangement. Simple structure, easier operation and maintainence.
Vertical Francis turbine unit, with vertical shaft, metal spiral case or concrete spiral case. With adjustable guide vane, and stay ring etc parts, are suit to runner diameter bigger than 1000mm. Our engineer will select the most suitable Francis turbine for your hydro power project.
Francis Turbine Components
1. Spiral Casing
Spiral casing is the inlet medium of water to the turbine. The water flowing from the reservoir or dam is made to pass through this pipe with high pressure. The blades of the turbines are circularly placed, which mean the water striking the turbines blades should flow in the circular axis for efficient striking. So the spiral casing is used, but due to circular movement of the water, it looses its pressure.
2. Stay Vanes
Stay vanes and guide vanes guides the water to the runner blades. Stay vanes remain stationary at their position and reduces the swirling of water due to radial flow, as it enters the runner blades. Thus making turbine more efficient.
3. Guide Vanes
Guide vanes are not stationary, they change their angle as per the requirement to control the angle of striking of water to turbine blades to increase the efficiency. They also regulate the flow rate of water into the runner blades thus controlling the power output of a turbine according to the load on the turbine.
4. Runner Blades
The performance and efficiency of the turbine is dependent on the design of the runner blades. In a Francis turbine, runner blades are divided into 2 parts. The lower half is made in the shape of small bucket so that it uses the impulse action of water to rotate the turbine.
The upper part of the blades use the reaction force of water flowing through it. These two forces together makes the runner to rotate.
5. Draft Tube
The pressure at the exit of the runner of Reaction Turbine is generally less than atmospheric pressure. The water at exit cannot be directly discharged to the tail race. A tube or pipe of gradually increasing area is used for discharging water from the exit of turbine to the tail race.
This tube of increasing area is called Draft Tube. One end of the tube is connected to the outlet of runner while the other end is sub-merged below the level of water in the tail-race.
