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.
What else can I help you with?
Cause of increase in LP Turbine differential expansion?
1. Low vacuum at high loads 2. High HRH temp 3.High steam flow 4. high gland steam temperature
What is the uses of packing steam in turbine?
The main uses for packing steam in a turbine are to produce electricity and power. The steam creates pressure when in turn spins a turbine at very high rates of speed.
What happen if the pressure get high inside the steam turbine condenser?
There has to be a built in expansion chamber or release valve. Otherwise the expansion would cause an explosion.
What is purpose to spray in exhaust hood of steam turbine?
The purpose of exhaust hood spray is to decrease the temperature of steam turbine last stage that is probably LP. This is operate on low load specially at start up and shut down of steam turbine when the temperature at the outer most edge of the turbine blades of that stage is very high and As we know that the steam flow also decrease The temperature of turbine blade.
What is difference bw condensing and non condensing steam turbines?
A condensing turbine uses all the energy from the steam going from high pressure turbine to secondary turbine to condensing turbine then sends the condensate back for reheating. where a non condensing turbine just uses the high pressure aspect of the steam then returns the low pressure stream back to be reheated. Condensng turbines utilises the entire available drop from high pressure to the vacuum in the condenser; a back pressure turbine only utilises only the top part, whereas an exhaust steam turbine utilises only th bottom part of the pressure drop. Hope that helps.
Why upon high axial displacement of steam turbine vacuum breaker opens?
The vacuum breaker in a steam turbine system opens upon high axial displacement to prevent damage to the turbine and maintain operational safety. High axial displacement can indicate abnormal operating conditions, such as excessive thermal expansion or load changes, which may lead to a vacuum forming in the turbine. By opening the vacuum breaker, it allows atmospheric pressure to equalize, thus protecting the turbine from cavitation and structural stress that could result from a vacuum condition. This mechanism ensures the turbine operates within safe limits and prolongs its lifespan.
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.
Cause of increase in LP Turbine differential expansion?
1. Low vacuum at high loads 2. High HRH temp 3.High steam flow 4. high gland steam temperature
How TO generate electricity from steam?
To generate electricity from steam, a steam turbine is typically used. High-pressure steam is directed onto the turbine blades, causing the turbine to spin. The spinning turbine is connected to a generator, which converts the mechanical energy into electrical energy.
What is the uses of packing steam in turbine?
The main uses for packing steam in a turbine are to produce electricity and power. The steam creates pressure when in turn spins a turbine at very high rates of speed.
Why to out bleed steam in turbine?
When steam contains liquid droplets while doing work at high temperatures, the water droplets can etch metal. To combat this, steam can be superheated or the pressure of the system is reduced.
What is turbine windage protection?
when steam flow blockage occured in steam turbine due to damage of blades/nozzles than steam temperature will increase so protect the turbine from high temperature this protection is introduced.
What is turbine blade angel?
turbine blade angle is that angle with which,a high presseure & high temprature steam is made to empenge on it.
High pressure steam turns the blades of?
High pressure steam hits the blades of a TURBINE and turns its shaft.
What should be the possible reasons of vacuum drop of turbine?
In the low pressure side of a steam turbine, the vacuum is maintained by the condensation of steam in the condenser. At high loads, the condenser may not satisify the demand, allowing steam to remain gaseous for a longer period of time. This can cause pressure to rise.
How does steam turbine works?
Steam or water, it works the reverse of a fan, where the fan pushes air down, the turbine is turned by the steam or water. there's a shaft leading from the turbine to the generator, which produces the electricity
Steam turbine if hot well level hig high what will happen?
If the hot well level in a steam turbine system is high, it can lead to several issues, such as reduced efficiency and potential damage to the turbine. High water levels can cause water carryover into the steam system, leading to water hammer and turbine blade erosion. Additionally, it may affect the operation of pumps and other components, potentially leading to operational disruptions or system failures. Proper monitoring and control are essential to prevent these complications.
