Steam Traps

Thermostatics Steam Trap – Balanced Pressure Type (BP)

The operating principle is based on the balance between the steam pressure and the internal pressure of the thermostatic membrane capsule, hermetically sealed and filled with a volatile fluid whose saturation temperature is lower than steam at any pressure. At start up the trap is wide open, freely discharging air, non-condensable gases and cool condensate. When the steam reaches saturation temperature, vaporization of the liquid inside the capsule creates a pressure differential which will shut the discharge orifice thus preventing any steam loss. When condensate inside the trap cools, the vaporized filling inside the capsule condenses thus reducing the internal pressure allowing the opening of the trap for discharge again.

Description

Steam is a very efficient and easily controlled heat transfer medium. It is most often used for transporting energy from a central location to any number of locations in the plant, where it is used to heat air, water or process applications. It is important to get steam to its various users around the plant as efficiently as possible. Efficiency translates into getting steam to the users with minimal loss in latent energy at a reasonable cost. This is where Steam Traps go into action.
A Steam Trap is simply an automatic valve that opens for condensate, air and CO2 and closes for steam. Without steam traps the condensate would form in distribution piping, creating problems.In identifying steam traps we can break them down into three main groups: Thermodynamic, Thermostatic, Mechanical.
In order to manage steam properly, amongst very few others in the world, CDB also supplies forged Piston Manifolds equipped with trap stations and condensate lift pumps to return the condensate back to the boiler for reuse.
