What is purpose of 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.
What are steam traps and how do they work?
A steam trap is a valve designed to sense the difference between steam and condensate, and drain the condensate from the line. Steam traps allow only condensate and gases to drain and “traps” the steam in to provide heat and power.
What happens if you trap steam?
Higher Steam Temperatures Problems With steam passing through the trap, the return condensate is at a higher temperature, which sounds like we are saving energy by not having to add as much sensible heat to the condensate to bring it back up to saturation conditions.
Where do steam traps go?
A steam trap is a device that removes condensate from a steam system. A typical steam system will have many steam traps – typically placed at 50-150′ after in straight pipe, after every heat exchanger (where the work gets done), and at every location where there is a change of elevation or pressure.
Where are steam traps needed?
In Front of Pressure Reducing Valves and Control Valves A steam trap should be installed immediately before pressure reducing valves / control valves to prevent condensate from pooling when the valve is closed. The trap also helps reduce erosion of the valve seat from condensate.
What happens if there is no steam trap?
When steam traps fail in a closed position, over time, the stagnant condensate will turn to carbonic acid (CO3). Carbonic acid will deteriorate all the metal with which it comes in contact. Beyond increased energy consumption, failed open traps also will cause control and efficiency issues.
How do you tell if a steam trap is blowing by?
Different sources state that if there is a high temperature differential across the steam trap station, then the steam trap is in good operational condition. If there is no or a very low temperature differential, then the steam trap has failed and is blowing or leaking steam into the condensate system.
What is function of a steam?
The main function of a steam boiler is to producing, storing and troubling the vapor. The liquid contained boiler is nothing but a shell and the heat energy produced while burning of fuel will be moved to water, and then it converts into steam at the required pressure as well as temperature.
What industries use Steam Traps?
Steam Trap Market, by End-User Industry:
- Chemicals.
- Energy and Power.
- Food & Beverages.
- Oil & Gas.
- Pharmaceuticals.
- Others.
How do you identify a steam trap?
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 long does a steam trap 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 is steam trap, its function and types?
Steam Trap Types Working and Function Steam Trap working. In general, a steam trap consists of a valve and a device or arrangement that causes the valve to open and close as necessary to drain the Ball Float Steam Trap. Bucket Steam Trap. Thermostatic Steam Traps. Bellows-Type Steam Trap. Impulse Steam Trap. Orifice-Type Steam Trap. Steam Traps Summary.
What are different types of steam traps?
Steam traps can be split into four major types: Mechanical traps. Temperature traps. Thermodynamic (TD) traps. Venturi Nozzle traps.
How does a steam trap work?
A steam trap is a device used to discharge condensates and non-condensable gases with a negligible consumption or loss of live steam. Most steam traps are nothing more than automatic valves. They open, close or modulate automatically.
What is a steam trap governed by?
Since trap operation is governed by the difference in density of steam and water, back pressure in the return line has no effect on the ability of the trap to open for condensate and close against steam. Virtually no steam loss Steam does not reach the watersealed discharge valve.
