Dryer Bars and Paper Dryer Performance

Dryer bars are axial bars placed on the inside of steam-heated paper dryers to create turbulence in the rimming condensate layer. If the spacing of the bars is chosen correctly, resonant waves are created in the condensate film, between each pair of bars.

White Water Recovery – the Benefits Go Beyond Just Saving Water

Corporate sustainability statements often emphasize water reduction as a goal associated with minimizing a company’s environmental footprint and impact on the community. Being a “good neighbor” by optimizing the use of water and reducing water costs are the two most obvious benefits.

Can Filtration Equipment Cost-effectively Reclaim White Water in Systems With a Variability in Solids?

Selecting filtration equipment that performs efficiently under the dynamic process conditions of paper machine white water loops can be a challenge for many papermakers. Variability in furnish, paper grades and the operating conditions of the machine, can lead to large swings in the type and amount of solids that must be removed from the white water before it can be reused in the process.

Advances in Press Roll Dewatering

Blind drilled, grooved, and suction drilled rolls are commonly used on presses in the papermaking process. The open areas in these rolls are designed to accept water from the fabric. It is important all the water in these rolls be evacuated before the nip to prevent re-wetting the sheet and to ensure optimum press nip performance. In some cases these rolls rely solely on centrifugal force to evacuate water, but this is often not sufficient, especially when the fabric becomes filled and cannot accept as much water.

Why Do My Steam Coils Freeze in the Winter?

Unfortunately, this happens too often. Repairing or replacing steam coils can be very expensive. Fresh air make-up steam coils are typically temperature controlled using a modulating steam control valve to regulate the discharge air temperature.
