Preventing Steam System Damage from Improper Flexible Metal Hose Installations
Proper flexible metal hose installations prevent stress on rotary joints and unions as well as connected piping due to thermal expansion, vibration, and misalignment.
Case Study: Liqui-Mover® Pump Succeeds Where Electric Condensate Pumps Failed
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.
Key indicators can help industry save energy
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.
Improved drying - Reduce thermal resistance with spoiler bars
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.
Predicting board quality hours ahead at Metsä Board
