A Hogger is a device to remove the Air from Turbine inside for creating initial vaccume for start up the turbine means create negative pressure inside Turbine or say creates less pressure than atmospheric pressure in Turbine.
An Ejector is a device used in Power plant to remove Undissolved gases from Condenser to avoid any harm to system from these gases.
If any correction is required pl. correct it.

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 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 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
How much steam is required to produce 5 MW power in steam turbine?
How much steam is required to produce 5 MW power in steam turbine?In fully condensing turbine we will need 20 TPH steam required to generate for 5MW
What difference between clockwise and anticlockwise rotation of steam turbine?
1- it is amatter of preference 2- considered under gyroscopic precession

What is the difference between back pressure steam turbine and condensate steam turbine?
In a back pressure turbine all available energy from the inlet steam is NOT used to generate power; steam exhausts at a tangible pressure and is then used for, usually, heating or chemical processing. In a condensing turbine, all the inlet steam does mechanical work right down to the lowest pressureafter which it is condensed in a heat exchanger
What is hogging ejector?
First is the "hogging ejector," which I prefer to call the "start-up ejector" because I think it is more descriptive of what this does. It is usually a large and rather inefficient brute-force ejector used to pull vacuum quickly on a process vessel. Once vacuum is attained, this ejector is shut off and taken off-line. The vacuum is maintained by the "holding" system. The hogging - or start-up- ejector is usually used in a batch process or on a steam turbine, an application where it is important to get the main vacuum system on-line quickly. Hogging ejectors are usually single-stage, but they have also been built as two- and even three-stage non-condensing systems.
What are the different types of steam engines?
Depends on how you want to catigorize them ... mobile or stationary piston or turbine condensing or non-condensing and weither the power comes from the steam pressure or from the vacumm you get when you condence the steam.
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.
What is the difference between turbine turning gear and barring gear?
both are same using for rotating the turbine initially
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 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?
it is difference between the water level from head race and tail race
What is vaccume breaker in steam turbine?
A vacuum breaker is a check valve installed on the exhaust casing of a turbine. It opens to prevent the collapse of the exhaust hood when the turbine cools and the condensing steam produces a vacuum.
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.
