What is the control stage in steam turbines?
The control stages are the stages at which steam is admitted to or extracted from the turbine. These "control" the output of the turbine.
How many stages of steam turbine rotor?
It depends upon megawatt of turbine & design of blades.
What is a steam turbine diaphragm?
Steam turbine is comprising of stages, number and size of the stages depands upon the break horse power of the turbine. The stage has set of moving and fixed blades. The moving blades are attached to the rotor while the stationary blades is called Diaphragm. The diaphragm guides the steam to glide over the moving blades for producing rotary motion.
How does a steam engine differ from a steam turbine?
Technically a steam turbine is a particular type of steam engine. A classic steam engine usually refers to a reciprocating steam engine, which uses a piston and crank arrangement, where pressurised steam (from the boiler) forces the piston through its stroke, producing output power. A steam turbine produces power with pressurized steam expanding to high velocity, and impinging on turbine blades which produce rotational output power. A steam turbine can be considered similar to a windmill, although steam turbines typicaly rotate much faster, and often have many stages of steam expansion within a single machine.
What is the cause of High Displacement in Steam Turbine?
High displacement in a steam turbine typically results from the design and operational parameters of the turbine, including the size and number of stages, as well as the steam flow rate. Increased steam flow leads to a larger volume of steam passing through the turbine, which can elevate displacement. Additionally, factors such as changes in steam pressure and temperature can affect the turbine's efficiency and capacity, potentially causing higher displacement. Proper design and operational adjustments are crucial to manage displacement effectively.
How does an extraction turbine work?
An extraction turbine is a type of steam turbine that operates by extracting a portion of the steam at intermediate pressure from the turbine for use in heating or other processes. As steam enters the turbine, it passes through various stages, converting thermal energy into mechanical energy to drive the turbine blades. The extracted steam is typically at a lower pressure and temperature, which makes it suitable for applications like district heating or process heating in industrial settings. The remaining steam continues through the turbine to generate additional power before being condensed and returned to the boiler system.
Why extraction taken from steam turbine?
Why extractions are taken out from steam turbine.
What is the function of super heater?
A superheater increases the temperature of the steam for use in a turbine or an engine. Without the additional heat, a multi-stage turbine or engine will get moisture (water) in the lower pressure stages as the steam cools, causing erosion of the blades or cylinders.
How do you decide number of stages for a steam turbine?
It is generally based on the Type of rotor ( Impulse/ curtis) and the enthalpy drop per stage.
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.
What are the preventive maintenance of steam turbine?
The preventive maintenance of steam turbine mainly entails frequent servicing of the parts. This will ensure a smooth performance of the steam turbine.
What is heat rate of steam turbine How to calculate heat rate of steam turbine?
