Francis Turbines - an overview ScienceDirect Topic

  1. Francis Turbines are generally installed with their axis vertical. Water with high head (pressure) enters the turbine through the spiral casing surrounding the guide vanes. The water looses a part of its pressure in the volute (spiral casing) to maintain its speed. Then water passes through guide vanes where it is directed to strike the blades on the runner at optimum angles. As the water flows through the runner its pressure and angular momentum reduces. This reduction imparts reaction on the runner and power is transferred to the turbine shaft.
  2. Guide vanes are also known as wicket gates. The main function or usages of the guide vanes are to guide the water towards the runner. The water flow must be an angle and that is appropriate for the design.

For power generation using Francis Turbine the turbine is supplied with high pressure water which enters the turbine with radial inflow and leaves the turbine axially through the draft tube. The energy from water flow is transferred to the shaft of the turbine in form of torque and rotation. The turbine shaft is coupled with dynamos or alternators for power generation. For quality power generation speed of turbine should be maintained constant despite the changing loads. To maintain the runner speed constant even in reduced load condition the water flow rate is reduced by changing the guide vanes angle.Parts: file came from: http://www.usbr.gov/power/data/fist/fist4_1a/4_1af5.htm, Public Domain, https://commons.wikimedia.org/w/index.php?curid=61660967

Francis, an American civil engineer comes up with his turbine called Francis turbine. What’s different he is doing!!!Today, hydropower contributes to 16% of the world’s power generation. In the 19th century, water turbines were predominantly used for industrial power before electrical grids became widespread. Currently, they are used for electric power generation and can be found in dams or areas where heavy water flow occurs.A water turbine, with the Kaplan, Pelton, and Francis turbines being the most common ones, is a large rotary machine that works to convert kinetic and potential energy into hydroelectricity. These modern equivalents of the water wheel have been used for over 135 years for industrial power generation, and more recently hydropower energy generation.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.

Francis Turbine is a combination of both impulse and reaction turbine, where the blades rotate using both reaction and impulse force of water flowing through them producing electricity more efficiently The Francis turbine operates a head range of 10 meters to several hundred meters and is primarily used for electrical power production.

Once you’ve established what kind of water pressure you can harness, you can then decide if an enclosed “reaction turbine design” like the Francis turbine or an open “impulse turbine design”, like the Pelton turbine is a better fit.

The stay vanes being stationary at their place, removes the swirls from the water, which are generated due to flow through spiral casing and tries it to make the flow of water more linear to be deflected by adjustable guide vanes.Lost your password? Please enter your email address. You will receive a link and will create a new password via email.As the water crosses the specially curved blades of the runner, the water is deflected sideways slightly. This causes the water to lose some of its "whirl" motion. The water is also deflected axially, so that it exits out of a draft tube to the tail race. This tube reduces the exit velocity of the water to obtain the maximum amount of energy from the input water. The process of water being deflected through the runner blades results in a force that pushes the blades in the opposite direction as the water is deflected. This reaction force (like Newton's third law) is what causes power to be transferred from the water to the turbine's shaft, maintaining rotation. Because the turbine moves as a result of this reaction force, Francis turbines are known as reaction turbines.[4] The process of changing the direction of the water flow also results in a decrease in pressure within the turbine itself.[2]

Water after passing through stay vanes, glides through guide vanes to enter the runner blades. Guide vanes can change their angle thus can control the angle of attack of water to the runner blades, making them work more efficiently. Moreover 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.

Mechanical efficiency:

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 means the water striking the blades of the turbine should flow in the circular axis for efficient striking. So, the spiral casing is used, but due to the circular movement of the water, it loses its pressure. It is the ratio of work done on the wheel to the head of water (or energy) supplied to the turbine.

These two forces together make the runner rotate.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. ANDRITZ HYDRO Francis Turbine. Bulb turbines. The solution for very low head and low output. ANDRITZ Hydro Francis turbines are characterized by incomparable longevity, durability, reliability.. The draft tube decelerates the fluid from the exit of the runner to the discharge to increase pressure and minimizes the loss of kinetic energy. The simulation found that the design could be improved upon to make this change more gradual to save energy. This aspect of the design was then chosen for optimization.

Evaluating the flow around the blades is imperative to decrease recirculation, which expends energy that could have been extracted for power. The simulation found that this appeared to be the case in the initial turbine design.The water coming out of runner blades would lack both the kinetic energy and pressure energy, so we use the draft tube to recover the pressure as it advances towards tail race, but still we cannot recover the pressure to that extent that we can stop air to enter into the runner housing thus causing cavitation.

The upper part of the blades use the reaction force of water flowing through it.  Thus runner blades make use of both pressure energy and kinetic energy of water and rotates the runner in most efficient way. Francis turbine is radial flow turbine but in case of modern Francis turbine water enters radially and leaves the turbine axially which is called as mixed flow turbine Difference in the pressure of water entering the turbine and that exists after striking the runner blades is too high, due to this pressure difference the air molecules which are relatively at high pressure then water coming out, enters the turbine casing in the form of bubbles. These bubble keeps on exploding near the surface of the runner blades continuously causing a shock wave, which produces a kind of defect at runners surface called cavitation, thus causing a serious problem for turbines efficiency. So what can we do is to prevent blades from cavitation? One solution is to use a really hard surface material like stainless steel or we can also go with surface Hardening of the runner blades, to prevent them from cavitation.The angle of guide vanes determines the angle of strikes of water at the runner blades thus make sure the output of the turbine. The runner blades are stationary and can-not pitch or change their angle. In short, the guide vane controls the power output of a turbine.
