Steam Trap Thermostatic Air Vent

Modern traps use a thermostatic air vent as shown in figure 11 3 2.

Steam trap thermostatic air vent. The most efficient means of air venting is with an automatic device. The best steam trap for this purpose is a float thermostatic type with steam lock release but a separate air vent is often still needed due to the large amount of air to be purged. Vent air from the system so steam can enter. On start up jacket is filled with air which must first be discharged by the air vents to allow steam to enter for heating.

The air vents for steam piping make use of thermostatic steam trap technology to discharge not only cold initial air but also hot air. When the steam condenses the hot condensate lifts the float moving the valve head off the. Hold steam in the system until the steam latent heat is removed. The functions of a steam trap in a steam system are to.

The float is closed at start up and stays in the closed position while steam is in the trap body. Air vent for liquid rapid initial air venting. Air vents on steam jacketed kettle system. The thermostatic air vent is open at start up to discharge large volumes of air to the condensate return.

Experience shows an air vent and an air collecting bottle at the condensate outlet will give an excellent result if fitted as shown in figure 11 13 1. The automatic air vent uses the same balanced pressure capsule element as a thermostatic steam trap and is located in the steam space above the condensate level. Float thermostatic steam traps contain a separate thermostatic vent and can discharge large volumes of air present during system startup. Typical applications include jacketed kettles retorts vulcanizers jacketed sterilizers or other.

Steam traps steam traps air vents float traps bucket traps hydro balance valves. This allows the initial air to pass whilst the trap is also handling condensate. This enables a thermostatic device based on either the balanced pressure or bimetallic principle to vent the steam system. As steam enters the trap body the air vent closes.

Ttf series stainless steel thermostatic air vents for pressures to 300 psig 20 bar. Water lifting pumps water transport lines water storage tanks. Stainless steel thermostatic air vent vacuum breaker tavb for pressures to 150 psig 10 bar. Capacities to 104 scfm 177 m3h armstrong offers thermostatic air vents for positive venting of air and other non condensable gases from steam in chamber type heat transfer equipment.

Capacities to 55 scfm 93 m3h the armstrong tavb is a combination thermostatic air vent vacuum breaker that is ideally suited for steam filled vessels with modulating controls. Air mixed with steam lowers the mix temperature.
