What does a steam trap remove?

What does a steam trap remove?

Steam traps are a type of automatic valve that filters out condensate (i.e. condensed steam) and non-condensable gases such as air without letting steam escape.

How do I remove condensate from steam?

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.

What’s the purpose of a steam trap?

The duty of a steam trap is to discharge condensate, air and other incondensable gases from a steam system while not permitting the escape of live steam.

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.

What is a condensate trap?

The idea of the condensate drain trap is to use the weight of the water to stop the flow of air produced by the blower from being sucked into (negative pressure) into the evaporator coil or from being pushed (positive pressure) out of the drain line during operation. …

How do steam condensate traps work?

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.

What is condensate steam?

What is Condensate? Condensate is the liquid formed when steam passes from the vapor to the liquid state. In a heating process, condensate is the result of steam transferring a portion of its heat energy, known as latent heat, to the product, line, or equipment being heated.

Can steam condensate go up?

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.

What is the pressure after steam trap?

After steam trap, each meter of elevation of the pipeline equals 0,11 barg back pressure.

Why do we remove condensate from main steam line?

Even in a straight pipeline without an obstacle, it is necessary to remove condensate, namely, discharge water every about 50 m. In an overheated steam transport pipe, since temperature of a pipe wall does not become below a saturation temperature, condensate does not generate during operation.

Does steam condensate water?

When the latent heat of steam is transferred to heat the product, that steam condenses into water, which is also known as “condensate”.

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.
