What are seal pots?
Seal pots (sometime called condensate pots) are used to allow a liquid seal between the instrument and flowing gases such as steam. Their function is to keep the liquid level constant in the impulse tubes. For example, in boiler liquid level applications the high pressure (HP) side of a differential pressure transmitter is connected to the vapor space on top of the steam drum. Steam condenses in the chamber or seal pot and fills the impulse line with condensate. The seal pot is located to allow the condensate to drain back to the source thus keeping the liquid level constant.
Is teflon tape required on flare fittings?
No, teflon tape (and pipe dope, for that matter) should never be used on flare fittings. They are designed to seal without tape or dope, and may actually leak if tape or dope is used.
Why the height kept of steam ejector 10.33 m?
So that it can maintain a vacuum on the condenser; and the U-drains, which drain back to the condenser, don't get sucked dry by the ejector set. The length of each leg of U-drain is specifically designed to maintain a certain vacuum at each position. The U-drains drain the condensate from the inter and after condensers and the gland seal condenser back to the main condenser. Water under a perfect vacuum will stand in a column 34 feet high (10.33 meters), which means a vacuum of 30 inches of mercury (762 mm) would draw everything out of a column that is not at least that high. It's to maintain the water seal on the U-drains to prevent air induction into the condenser.
Is Teflon tape use able on a fitting in a gasoline tank?
Teflon is inert to gasoline and all petroleum products. The problem with Teflon is it cold flows under pressure so that when tightened (when wrapped around your fitting) it will relax eventually and probably not seal properly. This is not something you want where gasoline can leak.
What is a wet cylinder liner?
In a wet cylinder liner the coolant of the engine runs in a space between the liner and the engine block. This gives excellent cooling, but is quite tricky to make good seal, particularly at the crank end of the cylinder. In a dry liner the coolant runs in channels in the block, and the liner is only like a sleeve stuck in a metal hole. Poorer cooling, but an easier build.
Why loop seal provided in cfbc boiler?
loop seal is provided to stop the material from furnace to return leg back.It works with the help of diffrential pressure.There is the difference in the pressure of air beteen furnace and return leg.
What is the purpose of Inert Gas deck seal onboard crude oil tanker?
The 'Deck Seal' and 'Non-Return Valve' are automatic and manual devices to prevent backflow. Backflow of gas could result in CH gas from the cargo tanks reaching the boiler, leading to an explosion.

Fuel feeding in cfbc boilers?
In cfbc boiler fuel system like a very important funtion of in all process. fuel feeding have two types one is over beding system and other one is under bed system.In over bed system coal is carried by conveyer belt from bunker to spreader that's time coal size approx 6-10 mm crushed.spreader distribute coal on the surface of bed uniformly.This type of fuel feeding system accept over size of fuel also.In compared with under feeding system this is more reliable.Now these days have some boiler have both feeding system.In under bed feeding coal size crushed approx 1-6 mm which is throw from conveyer to combustion panel.
What is the purpose of a conduit seal?
The purpose of a conduit seal is to provide ventilation in enclosures and prevent any moisture from entering that enclosure. It prevents any liquid, vapor or gasses from getting in.
What is the purpose of labyrinth seal?
To prevent the separation of the bearing side oil and the process liquid.
How do you build a hovercraft?
your going to need a piece of plywood and plastic and a leaf blower and 50ft. of string 1. cut out the piece of plywood to make a circle and cut out circle for leaf blower and a tiny hole near the edge for the string 2. next put the plastic on the bottom of the plywood circle and seal it on (it is important to seal because if you don't it won't lift) then take a piece of string and measure the bottom of the plastic, put the rope down and seal the edge around the rope. 3. add leaf blower and seal around it last thing you do is tie the string around the hole.
What is the purpose of a gasket?
to create an seal between two mating surfaces.
