What is cylinder in turbine?
Function of turbine cylinder in turbine operation:- Its function is to isolate the flow passage from the atmosphere to form the closed space for transferring the steam energy and the other static part (such as clapboard, nozzle room and so on) supporting the steam turbine.
What is multi cylinder turbine?
Multi cylinder turbine which have their rotors mounted on one and the same shaft and coupled to a single generator are known as single shaft turbines. Multi axial turbines have separate rotor shafts for each cylinder placed parallel to each.
What is double flow turbine?
In a double flow rotor, the blades in each half face opposite ways, so that the axial forces negate each other but the tangential forces act together. This design of rotor is also called two-flow, double-axial-flow, or double-exhaust. This arrangement is common in low-pressure casings of a compound turbine.
What is the pressure in a gas cylinder?
Most compressed gas cylinders, whether they are ultra-high purity or industrial grade, will be pressurized to around 2000 psi. This represents an enormous amount of potential energy.
What is a multi stage turbine?
a gas or steam turbine in which the expansion of the steam or gas from its initial pressure to its final pressure and the conversion of its thermal energy into mechanical work takes place in a number of stages arranged in tandem, rather than in one stage.
What is single stage steam turbine?
Single stage turbines are generally used to protect the plant against electrical power outages that would shut down critical pump or fan services.
What is steam chest in turbine?
Definition of steam chest : the chamber from which steam is distributed to a cylinder of a steam engine.
How many HP and LP cylinders are in a gas turbine?
These turbines consist of one double flow HP cylinder and three double flow LP cylinders. The LSBs are 1320 mm (52 in) long, providing an annular exhaust area of 16.7 m2 per flow.
How does a single cylinder steam turbine work?
Single cylinder construction or Single Flow Turbine Single cylinder turbines have only one cylinder casing (although may be is multiple sections). Steam enters at the high pressure section of the turbine and passes through the turbine to the low pressure end of the turbine then exhausts to the condenser.
What are the types of steam flow turbines?
9. 1. Type of Steam Flow Turbines may be classified according to the direction of steam flow in relation to the turbine wheel or drum-Axial. – Radial. – Mixed-Tangential Or Helical. – Reentry Prepared by Mohammad Shoeb Siddiqui Senior Shift Supervisor.
What is the reverse flow of a steam turbine?
12. Reverse Flow In some modern turbine designs the steam flows through part of the high pressure (HP) cylinder and then is reversed to flow in the opposite direction through the remainder of the HP cylinder.
