Vacuum breakers are frequently installed with the air inlet port facing up. This orientation can lead to contaminants entering the steam system and potentially accumulating on the ball, seat, and cage area of the vacuum breaker.

Dryer fabrics, often called dryer “felts”, are used to hold paper against the outer surfaces of steam-heated drying cylinders. The pressure from the dryer fabrics increases the rate of heat transfer from the dryer to the paper. The pressure that is applied to the paper depends on the fabric tension and the diameter of the dryer. The pressure can be calculated, as a first approximation, by the equation:

It has been well-documented that the distance between the condensate entrance of a syphon and the dryer shell, referred to as the syphon clearance, has considerable influence on the operational efficiency of a paper dryer. Suboptimal clearance adversely affects heat transfer capacity and the cross-machine temperature uniformity of the cylinder.
