Webb28 okt. 2024 · In effect, it's a cross between a simple de Laval impulse turbine and a multi-stage Parsons reaction turbine. Steam enters through nozzles at the top (yellow) then passes between a series of moving (blue) and stationary (red) blades before exiting at the bottom. It hits each blade and bounces off—just like in a simple impulse turbine. WebbSharing is Caring :)-As we all know about the turbine. They have vast application and can be classified in different ways.
