Steam Traps

Thermodynamic Steam Trap – Disc Type (TD)

The thermodynamic disc type is probably the simplest trap on the market and yet is the most widely used. The disc trap is made up of three primary components: the body, the cap and the disc. This type of trap is operated by the internal energy of steam. Condensate and air entering the trap raise the disc and flow continuously throughout the discharge orifice. Steam entering the trap expands suddenly as it reaches the underside of the disc. The resulting high flow velocity (kinetics energy) causes a decrease in pressure under the disc  (Bernoulli’s Principle). Steam above the disk is stationary, therefore at higher pressure, forcing the disc onto the seat and closing the trap. When condensate appears at the trap inlet, the steam above the disc condenses releasing the pressure and allowing the discharge cycle to repeat.

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.
