Where are steam traps used?
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. In industry, steam is used regularly for heating or as a driving force for mechanical power.
Why steam trap is used in steam line?
Steam Traps are automatic valves designed to remove condensate and non condensable gasses from steam lines, at the same time they prevent steam to pass through it effectively minimizing steam loss. The first function is to remove air and non-condensable gases from the equipment to which it is assigned.
What does a steam line do?
The steam lines are a critical components system in the boiler tower: in particular the main steam and hot reheat lines are made by thick pipes that are necessary to transfer the steam from the top of the boiler to the steam turbine room, generally located at ground level.
What are 3 types of steam traps?
Steam traps can be divided into three different types based on their operating principles:
- Mechanical Steam Traps.
- Thermodynamic Steam Traps.
- Thermostatic Steam Traps.
- Applications Suited to the Free Float® Type.
- Applications Suited to the Disc-Type.
- Applications Suited to the Thermostatic Type.
Where are inverted bucket steam traps used?
Applications of inverted bucket steam trap
- As process main drip traps for continuous operations.
- In steam lines where condensate is lifted or drains into wet return line.
- For heat exchangers without a modulating steam regulator.
- In high pressure applications.
- For drum type roller dryers.
- For steam separators.
What is SLR in steam trap?
This trap is provided with two optional features called Steam Lock release (SLR) and Thermostatic Vent (TV). The SLR is a manual operation to release steam that may hamper free movement of the float on water level.
How is steam pressurized?
Pressurized steam is generated inside the boiler by heating water. The steam is then transported through pipes to the point of use, such as radiant space heating, driving a turbine, or heating a process. When the water converts to steam, dissolved solids are left behind to concentrate in the boiler water.
Where are thermostatic traps used?
Thermostatic steam traps are also commonly used as air vents in steam systems.
What are mechanical traps?
Mechanical traps are steam traps that operate on the principle of specific gravity (specifically the difference in the specific gravities of water and steam), unlike other types of steam traps that rely on temperature change or velocity/phase change.
What is thermostatic steam trap?
Thermostatic operation Thermostatic steam traps operate on steam’s temperature difference from cooled condensate and air. When air collects, the temperature drops and the thermostatic air vent automatically discharges the air at slightly below steam temperature throughout the entire operating pressure range.
What is inverted steam trap?
In inverted bucket steam traps, the bucket within the trap is attached to a lever that opens and closes the trap valve in response to the bucket’s motion. When steam or air flows into the underside of the inverted bucket and condensate surrounds it on the outside, the steam causes the bucket to become buoyant and rise.
