Steam ejectors use steam or gas instead of moving parts to compress a gas. In a jet or ejector, a relatively high-pressure gas, like steam or air, expands through a nozzle.

The Unknown Cost Variables of Unscheduled Downtime

The human relationships have changed dramatically around the world since the start of the new coronavirus pandemic.

It depends. Dryer fabric tension holds the sheet in tight contact with dryer surfaces to increase the drying rate and uniformity of heat transfer.

My name is Rick Lull and I am a Senior Applications Engineer at Kadant Johnson. I have a degree in Paper Process Engineering and have worked as a Kadant Johnson applications engineer for 20 years.

The ABB Ability™ Performance Service provides auto-correlating calculations for online conditioned weight measurement to enable mills to reduce quality losses by getting on-spec faster during sheet breaks and start up events.

Paper machine dryers consume tremendous amounts of energy and have a direct impact on product quality, but the drying process is highly complex and requires extensive process knowledge to optimize.

Drives are an integral part of pulp and paper operations and need to run reliably every single day, according to the precise demands of the process.

Open Top Headbox Shower Eliminates Pulp Build- up in a Paper Production Factory

Russia, 2020 - Arkhangelsk Pulp and Paper Mill (APPM) is one of the largest producers of containerboard in Russia, producing over 500 000 TPY of fluting and Kraft linerboard.

There should be procedures in place both to start-up and to shut down a dryer section.

Effective data management requires having a strategy and reliable methods to access, integrate, cleanse, govern, store and model - to prepare data for analytics so that it adds value.

Asset condition management is not a new topic – it’s a new point of view. Instead of merely monitoring a valve or other devices, asset condition management captures the big-picture information and consolidates all improvement processes to help maintain highly reliable plant assets.

Proper flexible metal hose installations prevent stress on rotary joints and unions as well as connected piping due to thermal expansion, vibration, and misalignment.

A Fortune 100 company heats its multi-building campus from a central boiler house. To pump the return condensate, it was using electric pumps located in a sub-basement that flooded once or twice a year with up to eight feet of water.

By comparing different industrial processes, companies and official bodies can increase their knowledge about possible savings of energy. There is a huge potential for reductions in energy consumption and, in the long run, less impact on the climate.

It's hard to imagine how successful drying techniques would be today without the spoiler bar. It is based on the premise that the thermal resistance of the dryer's condensate layer can be reduced by fitting axial bars, or "spoiler bars" on the inside of the dryer shell.

At Metsä Board Kemi mill, the operators can see the board quality hours into the future and predict and prevent disturbances that cause end-product defects and runnability issues. Predictive Wet End, a new digital service by Kemira, increases transparency to the complex wet end chemistry.

A rotary joint or “steam joint” is a mechanical seal that connects steam piping to rotating drying cylinders.

An “insulating sleeve” is a flanged tube that extends through the bore of a paper dryer journal.

Paper manufacturer Laakirchen Papier AG demonstrated its future focus and adaptability by rebuilding its PM 10 from recovered magazine paper to corrugated medium in 2017.
