Application To avoid corrosion damage to steam boiler plants, the content of aggressive gases, such as oxygen and carbon dioxide, in the feedwater must be as low as possible. The German Technical Supervisory Association (VdTÜV) has issued directives concerning boiler feedwater quality which are applied by German boiler manufacturers when giving a warranty on their boilers. Thermal deaeration in addition to chemical deaeration is very important for maintaining the required feedwater quality.

trimod besta, the f lexible one. i t can be used anywhere, no matter where and when. i ts versati l ity is unl imited, for highest temperatures, freezing cold, low density, vacuum or high pressure appl ications.

The benefits of the wide spectrum of Trimod Besta switches are especially obvious in the industrial range. They are the best choice for high operating pressures, aggressive media and high process temperatures up to 400 °C.

Trimod Besta limit switches are successfully used in the ship building industry since 1967. They are installed in tankers, cruise ships, submarines, even in the fastest catamaran and the strongest crane ship in the world.

After continuous blowdown, irrespective of whether automatically controlled or manually set, it is easily possible to utilize the dissipated heat. For example, in a GESTRA blowdown flash vessel, the energy generated by the continuous blowdown is recuperated to a large degree by flashing.In a residual blowdown cooler located downstream, the heat remaining in the flash vessel can also be used to preheat the feedwater. Another possibility for heat recovery is offered by flash steam coolers. Flash steam coolers are, for example, applied in using the flash steam from the feedwater dea- erating plant to preheat the make-up water. Our experienced specialists in systems engineering and process technology are available to you for individual advice.

Condensate flash vessel Condensate flash vessels can be used in all steam plants where condensate from steam processors is reduced to a lower pressure, so that flash steam is formed by revaporization. In the flash vessel the steam is separated from the water, and then fed into a lowpressuresteam system. The condensate remaining in the flash vessel is discharged into a condensate tank.

Moisture and impurities in the steam are a causeof increased wear in steam systems. These may consist of water or dirt particles. GESTRA steam driers remove moisture and impurities from the steam line, thus extending the service life of control valves, heat exchangers and other steam users, and also increasing the reliability of the entire plant.

Heating installations in all industries Heating of drying calenders in the paper industry Heating of boiling pans in the foodstuff industry Heating of cable presses Radiant panels for hardware production in the electrical industry Steam moistening plants in the textile industry

Mixing coolers (a type of blowdown receiver) serve to cool hot waste water that can no longer be used for heat recovery and is therefore discharged into a pit or drain.

The condensate dampening pot provides acushioning effect to neutralize waterhammer. The condensate is discharged without noise.
