How high will a steam trap lift condensate?

Steam Condensate Lift using an On-Off Control Scheme This is enough pressure to lift the condensate 12 feet to a gravity return main.

How do you get condensate off a steam line?

Best Practices for Condensate Removal on Steam Lines

1. Best Practice #1: Choose Trap Locations Carefully.
2. Best Practice #2: Provide Proper Support and Inclined Steam Piping.
3. Best Practice #3: Pay Attention to Drip Leg (Drain Pocket) Configuration.
4. Best Practice #4: Properly Remove Air and Condensate at End of Steam Line.

How do I know if my steam trap is bad?

Condensate should usually be flowing through a trap, and the sound should have a lower pitch. So, if this sound changes and appears much closer to a higher pitched sound like that of steam flow, then the trap may have a large amount of flash steam or may be leaking live steam and should be inspected further.

How many pounds of steam does it take to lift a condensate?

5 pounds
We would need a little over 5 pounds of pressure to lift the condensate up and into the condensate pipe.

Can you lift steam condensate?

Lifting condensate from a steam main It is sometimes necessary to lift condensate from a steam trap to a higher level condensate return line (Figure 14.5. 1). The condensate will rise up the lifting pipework when the steam pressure upstream of the trap is higher than the pressure downstream of the trap.

How far can you pipe steam?

As a general rule, therefore, provided the branch line is not more than 10 metres in length, and the pressure in the main is adequate, it is possible to size the pipe on a velocity of 25 to 40 m/s, and not to worry about the pressure drop.

Why do we remove condensate from main steam line?

When this collides with a valve or a pipe bend part, big sound and vibration are produced. This phenomenon is called as water hammer. This may produce not only noise but joint loose to cause leak or may destroy a valve. To prevent such water hammer, sufficient condensate removal is required.

Where Should steam traps be installed?

Always install the steam trap in a location that is accessible by plant personnel. Install a visual indication of the steam trap performance on all process applications. The visual indication can be a sight glass or test valve. Locate the steam trap below the lowest condensate discharge point of the equipment.

What happens when steam trap fails?

Failed traps will prevent proper operation of sensitive equipment. When steam traps fail in a closed position, over time, the stagnant condensate will turn to carbonic acid (co3). In some cases water hammer can occur when a portion of the steam condenses into water within steam piping.

How long do steam traps last?

approximately six years
Steam traps last approximately six years. Leaks may not be visible, so thermal imaging can be used as a testing measure. Repairing or replacing failed steam traps will improve steam system efficiency and occupant comfort, while reducing the amount of natural gas required.

What temperature is steam at 15 psi?

Saturated Steam Temperatures

How hot is steam condensate?

Significant fuel savings occur as most returned condensate is relatively hot (130°F to 225°F), reducing the amount of cold makeup water (50°F to 60°F) that must be heated. A simple calculation indicates that energy in the condensate can be more than 10% of the total steam energy content of a typical system.

How do you install steam traps?

Installing Steam Traps. The installation of steam traps requires the following modifications in the piping: 1. Install a long vertical drip and a strainer between the trap and the apparatus it drains. The vertical drip should be as long as the installation design will permit.

Where is the steam trap located?

Steam traps may be found on steam heating systems both on radiators (at the radiator bottom opposite end from the entering inlet valve), and on older steam heating systems a steam trap may also be found on some steam piping where the trap handles condensate produced inside the steam riser piping.

What are the different types of steam traps?

Steam traps can be divided into three different types based on their operating principles: Mechanical steam traps (also referred to as “density traps”) include Free Float®, lever float, and inverted bucket steam traps.

How does a steam trap operate?

Venturi steam traps operate by continuously removing condensate from the steam system. It allows any condensate present in the steam line to pass into the condensate return system as it is formed. The operation of the trap is based on the difference in density between water and steam.
