Wood Pellet Manufacturing
100,000-SCFM and 150,000-SCFM RCOs installed on existing hammer mill (ten lines) and pellet mill cooler (five lines) baghouse exhaust ducts. Project included fabrication and installation of the RCOs, as well as design, fabrication and installation of two extensive and intricate exhaust duct systems connecting the customer mills to the RCOs. Included: five replacement exhaust fans, two emergency dump stacks, two 85-foot exhaust stacks, platforming, duct supports, exterior lighting, fire suppression systems, thermal insulation, control dampers, and return-to-process ducts.
At this existing wood pelletizing plant, organic emissions needed to be conveyed to two multi-chamber RCOs. Specifications included replacement of five process exhaust fans, as well as the supply of a complete exhaust duct system.
NESTEC contractors installed much of the duct, duct supports, and controls during normal plant operations, without disturbing production. Cut-ins to existing process stacks were made on carefully planned line shutdowns. The existing equipment layout inside the plant buildings was extremely tight, and the new duct had to be exactly placed. All specifications were accurately measured by NESTEC designers working in the field, and the resulting ductwork fit without problems.
“Exceptional care was taken to meet the stringent plant construction safety requirements.”
The tight six-month installation schedule was closely managed, and the October 2013 end date for Field Acceptance Tests was met. Exceptional care was taken to meet the stringent plant construction safety requirements.
The final system achieved the required destruction/reduction performance required by contract and state permits. The customer’s European-based project management team, which worked closely with NESTEC’s engineers and project manager, followed ISO 9001 procedures in managing the project. NESTEC performed on time and within budget.
