Steam Trap

What is steam trap? (Central BOE-2021)

A steam trap is a valve that automatically discharges condensate from steam systems while preventing the escape of live steam. This is important because condensate can interfere with the efficient operation of steam systems by reducing heat transfer and increasing corrosion. Steam traps are used in a variety of applications, including power plants, industrial facilities, and commercial buildings.

There are several different types of steam traps, but they all work on the same basic principle. As steam condenses, it forms a liquid that is heavier than the surrounding steam. This condensate collects at the bottom of steam pipes and equipment. The steam trap opens to allow the condensate to drain out, but it closes quickly to prevent the escape of live steam.

Steam traps are an essential component of steam systems. They help to ensure that steam systems operate efficiently and effectively. Here are some of the benefits of using steam traps:

* **Improved heat transfer:** Condensate can interfere with heat transfer by forming a film on the inside of steam pipes and equipment. Steam traps remove this condensate, allowing steam to transfer heat more effectively.
* **Reduced corrosion:** Condensate can also cause corrosion of steam pipes and equipment. Steam traps remove condensate, helping to protect steam systems from corrosion.
* **Reduced energy consumption:** When steam is allowed to escape from a steam system, it represents a loss of energy. Steam traps prevent the escape of live steam, helping to reduce energy consumption.

In addition to these benefits, steam traps can also help to improve safety in steam systems. By preventing the escape of hot steam, steam traps can help to reduce the risk of burns and other injuries.

Here are some of the common types of steam traps:

Mechanical traps:- Mechanical traps use a float or ball to open and close the valve.
Thermostatic traps:- Thermostatic traps use a temperature-sensitive element to open and close the valve.
Thermodynamic traps:-Thermodynamic traps use the difference in pressure between steam and condensate to open and close the valve.

The type of steam trap that is best for a particular application depends on several factors, such as the pressure of the steam system, the temperature of the condensate, and the amount of condensate that needs to be discharged.
