Difference between hogger and ejector of condensing turbine?
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.
The principle of an air ejector?
The primciple of the air ejector is to exhaust the air remaining from the processor in excess amount.
Why used hogger and ejector in steam turbine?
A steam turbine condenser equipped with ejectors is usually fitted with two ejectors. The larger of the two is called the hogger and the smaller the huffer. Steam turbines are designed for efficiency and thus attempt to extract as much energy from the steam passing thru as is physically possible. Energy is extracted as both temperature and pressure decrease. The lower the temperature and pressure at the steam turbine's exhaust the more energy can be extracted from the steam. For this reason it is desirable for the steam turbine condenser (the exhaust) to be at the lowest temperature and pressure possible. The hogger, or hogging jet, is a large steam powered ejector that causes the steam condenser to operate under a near perfect vacuum whilst the steam turbine is in the start-up phase. In steady state operation the cooling effect of the condenser cooling water of the steam causes the condenser to operate under a nearly self sustained vacuum. The hogger is necessary in the start-up phase to prevent steam from condensing to water in the final stages of the turbine before the steam flow and cooling effect of the condenser can establish vacuum. The huffer or huffing jet runs continuously whilst the turbine is operating to remove any non-condensable gasses (i.e. air) that might leak into the condenser. It is nearly impossible to perfectly seal a condenser and turbine from air-in leakage. It should be noted that modern, large steam turbines do not employ steam ejectors to establish and maintain condenser vacuum. Modern designs utilize motor driven mechanical vacuum pumps.
What is the working principle of steam jet air ejector?
what is the woking principal of steam jet ejector? limitation of steam jet ejetor?
What are the reasons of failure of steam jet ejector Steam jet ejector is not able to sustain vacuum.Why?
Check the seals and connections for a leak allowing air to infiltrate and thus causing loss of a vacuum VERY common problem as the coefficient of expansion per degree causes havoc on metal to metal connections such as a pump connected to ejector housing

What is the function of ejector in steam turbine?
An ejector pump is a tool used usually in basements when the sewer fails to flow beneath the basement floor. Basically the function of this tool is to pump water so that the sewer in the basement could work continually.

How do you remove ejectors on a lanber?
Got an answer from the importers. The Ejectors are held in place by the Ejector Trips, these run vertically up and into a slot on the ejectors. On the ejector trip is a very small pip with a hole in it, underneath this hole there is a small plunger and coil spring (this keeps the ejector trip in place, not allowing the ejector trip to drop down). To remove the ejector you need to have a small pin punch that you place into the hole of the pip. The process of removing the ejector is as follows, keeping the ejector held into the barrel, insert pin punch into pip hole (depressing the plunger and coil spring), pull the ejector trip very slightly downwards. Releasing the ejector it should now slide out. When replacing the ejector all you need to do is push ejector back into barrel and at the same time push ejector trip upwards locking ejector and ejector trip in place.
Why is a blast cleaning hose called a hogger?
A hogger - more commonly a hog - is a tool that removes material from a workpiece rapidly. A large semicirclar drill bit is also known as a hog, or a wood hog.

What are ejector nozzles used for?
Ejector nozzles are used in jet engines. They are the simpler of the nozzles used and are more conventional that iris nozzles. Ejector nozzles are part of a group that includes ejector, iris, rocket, and low-ratio nozzles.
