STEAM TURBINE OPERATING PRINCIPLE In this video I will talk about the principle of operation of a STEAM TURBINE and remember some principles of thermodynamics that work in TURBINE A STEAM, but take it easy, it won't be too heavy or too long. First, let's remember the energy of the fluids. Every fluid basically has 3 basic forms of energy: speed (kinetic energy), temperature and pressure. Now let's remember a little how these forms of energy relate to STEAM TURBINE. You will see that STEAM TURBINE is basically a closed thermodynamic system where we have a certain fluid, in this case the steam, at a certain speed, temperature and pressure During the operation of a STEAM TURBINE the rotor blades absorb part of the steam energy , then these three forms of energy decrease, namely: Speed, temperature and pressure fall throughout the operating cycle. In this video we’ll see how it happens. A turbine vane has an aerodynamic profile, when the high energy vapor passes over it, this profile creates a pressure difference, which results in a lift force, aided by the principle of Newton's law (action and reaction). This holding force causes the STEAM TURBINE rotor to rotate. Remember that we said that the reeds absorb energy from the steam and that the 3 forms of energy decrease (speed, pressure and temperature?) So, we can already imagine that the low speed of the steam is not effective and sustainable in the lift force and do the rotor remains rotating. This is where the secret behind the STEAM TURBINE principle comes from, which is to pressurize the steam to extract its maximum energy through the ENTALPIC JUMP, transforming it into mechanical energy by increasing its speed. And those who play this role in the STEAM TURBINE are the diaphragms and expansion plates that have the function of increasing the steam speed. How do these pieces do this? In this video you will understand. So on, the process is repeated for as many stages as there are in the STEAM TURBINE ... note that there is a perfect meeting angle between the flow of steam that leaves the diaphragms / expansion plates and enters the vanes and vice versa. As the steam pressure is drastically reduced during the operation of the STEAM TURBINE, its volume increases proportionally to accommodate all this expansion of the steam. And for that, the flow passage area has to be increased to maintain the system speed, otherwise the speed at the outlet or discharge as we call it would be very high. For this reason, the blades in the last stage are much larger than those in the first stage. Larger blades will need to withstand much greater mechanical stresses and stresses.
