what is purpose of nozzle in steam turbine?
It sends hot gases from the combustion chamber to the 1st stage turbine blades at the correct angle and speed
What is the working principle of steam turbine?
The Steam Turbine is the one which steam worked pressured Hot and exited then the shaft of the turbine starts to and fro motion due which energy is injected through nozzle in the receiver.
Why is convergent-divergent nozzle generally used in steam turbines?
A convergent-divergent nozzle is generally used in steam turbines. This is because it drives generators in producing electricity with the use of turbine rotors with curved axes.
Why is nozzle control governing not employed a reaction turbine?
in reaction turbine pressure compounding is employed as every stage has a set of nozzle ring nozzle control is not feasible.
What is different betweeb single stage and multi stage steam turbine?
In a single stage steam turbine the steam is run through a nozzle to give it maximum velocity, thus the blades move at very high speeds, impractical for some applications, and only some of the energy is used, about 85-90%. In multi-stage or compound turbines the steam goes through a nozzle to increase its velocity, then after going through a set of blades, it is run through another nozzle to bring the steam back up to the correct velocity. After multiple stages there is no longer enough pressure left to up the velocity of the steam. This method increases the efficiency of the turbine and also decreases wear on the components caused by the high speed of a single stage.

What does steam do to a turbine?
Steam (under pressure) comes into contact with the blades of the turbine through which it is flowing and, by the direct application of force, causes the blades to move, turning the turbine shaft. The turbine coverts the thermal energy of the steam into (rotating) mechanical energy. Surf on over to our friends at Wikipedia using the provided link and get more info. Oh, and check out the pics! Answer it depends what type of turbine one is using types of steam turbine 1 impulse turbine 2 reaction turbine in 1 st one steam is completely expanded inside nozzle and all pressure energy get converted in to kinetic energy using this impulse force turbine runs. in 2nd steam is multiple stage blades are used where high pressure superheated steam gets expanded inside the turbine in each stage and after each stage velocity of steam increases. very high temperature superheated steam is reaquired because it has very high specific volume which helps in reducing mass flow rate of steam.
Why extraction taken from steam turbine?
Why extractions are taken out from steam turbine.
How does a terry turbine work?
Terry was the name of a steam turbine manufacturer. The company was bought by Dresser-Rand some years ago. I don't think they sell this model now, only spare parts. The basic design is that of an impulse turbine (as opposed to a reaction turbine). The unique feature with Terry is the nozzles feed steam radially inward to a single rotating wheel with blading on the circumference. The blades are semi-circular so the flow path is spiral between the blades and the stationary nozzles. They are arranged in sets of an inlet nozzle with 4 or 5 reversing nozzles before the spent steam is exhausted. The number of nozzle sets depends on the steam rate.
Show and label the components of the Hayward-Tyler-Terry steam turbine?
The Hayward-Tyler-Terry steam turbine consists of several key components: the rotor, which houses the blades that convert steam energy into mechanical energy; the stator, which contains stationary blades that guide the steam flow; the nozzle, where steam expands and accelerates before entering the rotor; and the bearings, which support the rotor and allow it to spin. Additionally, the casing encloses the turbine, maintaining pressure and directing steam flow. Together, these components work to efficiently convert thermal energy from steam into rotational energy.
Why would you not heat the steam coming out of turbine and feedback to turbine?
Steam is redirected back into the boiler from the high-pressure turbine for reheating, but the steam from the low-pressure turbine enters into a condenser to become water again.
Does a steam turbine convert heat energy to kinetic energy?
When one basically sees the flow system in a power plant, then following formula for is-entropic process is important: h+(V2/2) = constant heat energy is related to 'h'(enthalpy). The conversion of 'h' to 'V'(velocity) takes place in a CD (convergent divergent)nozzle, where the steam expands and 'h' is converted into kinetic energy of steam (in turn steam gets a huge momentum)which turn the steam turbine. So basically the kinetic energy for the steam is developed in CD nozzle itself (from decreasing enthalpy which was generated due to heat energy in super heater or the boilers), which turns the turbine.
