Success Story

Pressure Power Pump Installations Promote Low Cost and Line Efficiency

Smurfit-MBI in New Westminster British Columbia has been producing quality containerboard for over 50 years for a variety of nationally well-known retailing customers. A project to increase the width of the double facer table to produce more containerboard resulted in a call to Andrew Reynolds.

The old cascading system would occasionally result in lower line speeds when running double walled board. Increasing the deck width raised a concern that line speeds may drop even more due to the temperature required to cure the board. After reviewing the project, a proposal was made to Ed Baarscheers, the Chief Engineer and Project Manager.

Individually control the steam to each of the three hot deck sections to maintain temperature by using a combination of salvage steam from the double backer and line steam from the boiler. Additionally, to maintain the required temperature, the individually controlled sections needed the condensate to be removed as soon as if formed. Pressure powered pumps on each plate section insured condensate was removed immediately, regardless of the upstream steam pressure.

The results were reduced costs, improved quality, improved line speeds, and a system that is flexible to the meet the production requirements for all of Smurfit-MBI’s customers.

Mr. Baarscheers reports, “We are pleased with the system. It has performed as we hoped for and anticipated.”

Deaerators in Industrial Steam Systems

Deaerators are mechanical devices that remove dissolved gases from boiler feedwater. Deaeration protects the steam system from the effects of corrosive gases. A dissolved oxygen level of 5 parts per billion (ppb) or lower is needed to prevent corrosion in most high-pressure (>200 psi) boilers. While oxygen concentrations of up to 43 ppb may be tolerated in low-pressure boilers, equipment life is extended at little or no cost by limiting the oxygen concentration to 5 ppb. Dissolved carbon dioxide is essentially completely removed by the deaerator.

Client Testimonial

Andrew worked with me on a turnkey hot water tank replacement managing the contractor in the demolition and installation of a new instantaneous hot water heater. The project proceeded smoothly and the system worked as promised. It has been in operation for a number of years now with no complaints. Andrew has the products and knowledge I know I can trust.
