bleed is amount of steam output from turbine through pipe and exit from final stage of turbine . this bleed enter to feed water heater (low and high) and deaereator to increase unit efficiency
or rather bleed is the amount of steam drained out of the steam turbine during the expansion of steam and this rejected heat energy is used to heat the feed water supplied to the boiler...........

What is the difference between volute centrifugal pump and turbine centrifugal pump?
voloute convord the pressure into volicity and the mixtur of propallere and impeller is called turbine pump
What difference between clockwise and anticlockwise rotation of steam turbine?
1- it is amatter of preference 2- considered under gyroscopic precession
What is difference between pelton wheel and turgo turbine?
pelton turbine is used for high head low flow but the turgo turbine is used for low head high flow, in pelton turbine number of jet can increased but in turgo it can't be done, in pelton the water hits the bucket once at a time but in tugo it hits more than one
How ESV in turbine works?
The Emergency Stop Valve (ESV) in a turbine is placed between the steam engine and the turbine structure. It is designed to rapidly close and prevent steam from reaching the turbine in case of emergency.
Why extraction taken from steam turbine?
Why extractions are taken out from steam turbine.
What is controlled and uncontrolled extraction in double extraction steam turbine?
The extraction of steam can either be controlled or uncontrolled. In an uncontrolled extraction the pressure of the extracted steam will decrease with an increase in extraction flow from the turbine. In a controlled extraction the extraction pressure is kept constant as extraction flow is increased or decreased.
What is the difference between turbine and machine?
the machine is the one that operates or makes the turbine work. the machine is the one that operates or makes the turbine work.

both are same using for rotating the turbine initially
What is the difference between generator turbine?
RADITOR * Small generators either air cooled or water cooled 2 stroke. Autos are mainly 4 stroke and the majority watercooled.
The gross head in turbine installation is difference of level between?

What is the difference between a Gas turbine engine ignition system and a piston engine ignition system?
Main difference is that in a gas turbine, combustion is continuous. In a piston engine, combustion is pulsed.
What is difference between radial flow turbine and axial flow turbine?
in a radial flow turbine the steam enters the turbine in the direction of its radius and leaves it in the direction of the axis of the shaft. in a axial flow turbine the steam enters the turbine in the direction of the axis of the shaft and leaves the turbine in the same direction.
What is the difference between volute centrifugal pump and turbine centrifugal pump?
voloute convord the pressure into volicity and the mixtur of propallere and impeller is called turbine pump
What is the difference between 500MW and 600MW power station?
The ans is with respect to Thermal Power plants: the basic difference between a 500MW plant and 600MW palnt is in the turbine design. the 600MM turbine has 1 HPT, 1IPT and 2 LPTs, 2 Condensors and a generator. the 500MW turnbine has 1 HPT, 1IPT and 1 LPT, 1 condensor and a generator. HPT: high pressure turbine IPT: intermediate pressure turbine LPT: low pressure turbine
What is the difference between back pressure and absolute pressure in steam turbine?
Back pressure is the small amount of vacuum that is created when the used steam condenses from the turbine back into re-usable water.
Difference between francis and kaplan turbines?
The comparison kaplan and francis hydro power turbine is as under: 1. Efficiency of Kaplan hydro power turbine is higher. 2. Kaplan turbine is more compact in cross-section and has higher rotational speed to that of francis hydro power turbine. 3. In Kaplan turbine, the water flow is axia and in francis trubine it is radial. 4. The runner blades in the kaplan turbine is less in number. 5. Specific speed of Kaplan turbine is 2 to 3 times that of Fancis turbine. 6. Friction loss in Kaplan turbine is less. 7. Francis turbine requires medium head while Kaplan trubines are low head hydro power turbines.
