The Francis Hydro Turbine Generator is a type of water turbine. It is an inward-flow reaction turbine that combines the concepts of radial and axial flow. The Francis Hydro Turbine Generator is one of the most commonly used turbines today, with efficiencies exceeding 95%.

The design process for modern Francis turbines spanned from 1848 until around 1920. Around 1920, this turbine became known as the Francis Hydro Turbine Generator, named after the American engineer James B. Francis, who created a new turbine design in 1848.

The Francis Hydro Turbine Generator is primarily used for electricity generation. The power output of generators typically ranges from a few kilowatts to 1000 megawatts, though small hydroelectric installations may have lower power. Performance is optimal when the head height is between 100 and 300 meters (330 to 980 feet). The diameter of the pressure pipe ranges from 1 to 10 meters (3.3 to 32.8 feet). The rotational speed of different turbine units ranges from 70 to 1000 revolutions per minute. The guide vanes on the outside of the rotating runner control the flow rate through the turbine to achieve various power outputs. The Francis Hydro Turbine Generator is usually installed with a vertical axis to separate the water from the generator, which also facilitates installation and maintenance.

The main components of the Francis Hydro Turbine Generator are:

  • Spiral Casing: The spiral casing around the turbine runner is also called the volute or spiral casing. The entire length of the volute has many evenly spaced openings to allow the working fluid to impact the runner blades. These openings convert the pressure energy of the fluid into kinetic energy before it impacts the blades. Despite providing many openings for the fluid to enter the blades, the cross-sectional area of the casing decreases uniformly around the circumference to maintain a constant velocity.

  • Guide Vanes and Fixed Blades: The main function of the guide vanes and fixed blades is to convert the pressure energy of the fluid into kinetic energy. They also direct the fluid at the designed angle to the runner blades.

  • Draft Tube: The draft tube is the conduit connecting the runner outlet to the tailrace, where water exits the turbine. Its main function is to reduce the velocity of the exiting water flow to minimize kinetic energy loss at the outlet. This allows the turbine to be placed above the tailrace, without significantly reducing the available head.

The Francis turbine is a reaction turbine, where the working fluid enters the turbine under high pressure, and the turbine blades extract energy from the fluid. Part of the energy is released by the fluid, as the pressure changes on the turbine blades can be quantified by the reaction degree, while the remaining energy is extracted by the turbine’s volute. At the outlet, water impacts the rotating cup-shaped runner and exits at low speed and low swirl, leaving very little residual kinetic or potential energy. The shape of the turbine outlet pipe helps to decelerate the water flow and restore pressure.
