What is HP and LP turbine expansion?
HP Turbine is High Performance Turbine LP Turbine is Low Performance Turbine
What to do about turbine rotor differential expansion?
my LP turbine differential expansion increase ,when rated gland steam temperature maintain.
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.
Why you keep condenser rupture disc in steam turbine?
You want the rupture disk located at the LP exhust side of the steam turbine. This is placed here to prevent over pressure of the condencer in case loss of vacuum occurs. It is not placed in the condencer because the condencer is not rated for pressure.
Why vacuum is created in condenser on steam turbine?
Firstly, vacuum is being created in turbine exhaust and condenser rather than being required. It is created to reduce the back-pressures and to improve the turbine efficiency. Also, with vacuum the designers can design large size last stage blades of LP turbine for maximizing the turbine output.
What is HP and LP turbine expansion?
HP Turbine is High Performance Turbine LP Turbine is Low Performance Turbine
When two or more turbine wheels are used in a jet engine what is placed in front each turbine wheel?
turbine stator (nozzle diaphragm)
What to do about turbine rotor differential expansion?
my LP turbine differential expansion increase ,when rated gland steam temperature maintain.
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.
Why vacuum breaker is provided in condensing turbine exhaust?
it is mainly provided to save the difram of lp turbine, it is initially use to seal d vacuum's.
What is lp and hp heaters?
In regenerative cycle LP/HP heaters are used to raise condensate/feed water temperature by extracting/bleed steam from LP and Hp stages of steam turbine in order to improve the efficiency of the plant
Why lp heater have no qcnrv?
non-return valves of swing check type provided with a forced closing mechanism. They are installed in turbine extraction lines. The purpose of these valves is to prevent the back flow of heavy specific weight and low temperature steam to turbine during a turbine trip
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.
If the diaphragm in the booster is bad and the breaks are not working great will your vehicle pass emissions?
yes but it will not pass the safety check
Why do we need th diaphragm?
Because if it is not fully lined and you don't use a condom or it breaks there is a high chance that you can and will get pregnant.
How does air tools work?
They have a turbine that acts as motor, and when air pressure turns it they rotate. Air nailers use air pressure on a diaphragm to fire a small shaft that does the action.
Why you keep condenser rupture disc in steam turbine?
You want the rupture disk located at the LP exhust side of the steam turbine. This is placed here to prevent over pressure of the condencer in case loss of vacuum occurs. It is not placed in the condencer because the condencer is not rated for pressure.
