Optimization of Fläkt Pulp Dryer for Increased Production and Efficiency

Western Alberta, Canada

In fall of 2015, the eSteamG Team, then working under the banner of MEI Resources, was hired by a western Alberta pulp mill to assess the Fläkt Pulp Dryer to improve efficiency and optimize performance. The dryer was typically constrained at a production level of 1150 ADTPD and was the main bottleneck of the mill’s overall production capacity.
The Assessment noted an unfavorable coil interaction, excessive venting of steam, flooding of the steam coils, and other signs pointing to poor steam efficiency and an opportunity for dry end production increases.
The work was implemented in three phases:

 

KEY OUTCOME: Achieved substantial steam and energy savings; assessment of increased production capacity ongoing.
