STATEMENT OF WORK

Project Title:

Field Trial of a High Capacity Gas-Fired Paper Dryer

Contractor:

Minnesota Department of Commerce, State Energy Office
85 7th Place East, Suite 500
St. Paul, MN 55101
(651) 296-1883

Program Area:

Industrial

Partners:

New Jersey Board of Public Utilities (NJBPU)
Conservation Services Group (CSG)
Proctor Engineering Group
Nexus Market Research
Northeast Energy Efficiency Partnerships, Inc. (NEEP)

Project Description:

Field-evaluate and confirm the technical and economic benefits of an innovative, lower cost, gas-fired paper dryer. The key features of this technology are a rotating drum inner surface that contains a dimpled profile that intensively transfers heat from the combustion products produced by a flame sheet to the paper web. Field demonstrating this high-efficiency gas-fired dryer will ultimately help the paper industry reduce its energy use and increase production of dryer-limited paper machines by 10 to 20%.

Management Plan (Approach):

The unique nature of STAC requires that projects be supported by multiple State entities, and to the extent necessary any other entity. As indicated in the STAC Agreement, it is the Contractor’s responsibility to coordinate the execution of work under the Contract, incorporated by reference hereto. Contractor, in conjunction with the other State entities, and to the extent necessary any other entity, shall conduct the project in accordance with the Management Plan (approach) described below.

The Minnesota State Energy Office, as the contractor, will provide overall management of the project including subcontracting for consulting services by Western Michigan University. Ms. Linda Limback of the Minnesota State Energy Office will be the contact point for this project. GTI has been working and is presently working with WMU for over one year in the pilot-scale testing phase of the precursor to this project and expects to transition and coordinate both project management and technical logistics with MN SEO and WMU. Additionally, MN SEO will support the technical work with their engineering staff during the course of the project. GTI will perform the bulk of the technical work effort except for the fabrication of the dryer drum, burner fabrication and external combustion system which will be, fabricated and assembled by GL&V USA INC. and Flynn Burner Corporation, respectively. GTI also will provide overall technical management of the project, and issue periodic and final report for the project. GL&V USA INC. and Flynn Burner Corporation will provide monthly reports to GTI. In addition to using these reports to monitor the progress of the project, GTI will periodically meet and confer with project team members to coordinate activities and review results.

Task 1: Preliminary Designs

With oversight from the Minnesota State Energy Office, GTI and WMU will evaluate the performance data from a previous pilot-scale trial and develop the preliminary design of the full size gas-fired drum and the internal combustion system. Work will focus on number and placement of dimples; shell thickness; internal combustion system capacity; elements making up burners and recuperator including internal waste gas recirculation system; and the natural gas and combustion air delivery system.

Task 2: Final Designs

GTI and WMU will review and finalize fabrication/assembly drawings and conduct a field site technical visit to evaluate position of current steam dryer drum to be replaced with the gas-fired paper drum. The team will evaluate the operational specifications and performance, and review the dimensional footprint. In addition:

GTI with WMU will schedule review meetings to finalize design and specifications of integrated gas-fired drum
GTI will prepare topical technical report
Project team technical review and determine if the activity is “Go or No Go”

Task 3: Field Trial

GIT and BPS will secure the necessary environmental and other pertinent permits for the filed trial and GTI will negotiate a field test agreement with BPS. GTI and GL&V USA INC. will fabricate the gas-fired paper drum, fabricate and assemble the internal and external combustion systems, integrate the internal combustion system into the gas-fired paper drum and transport the unit to the field trial site.

GTI will prepare a field trial plan and test matrix for 1) Baseline monitoring and for 2) Field Trial monitoring. WMU and BPS will assist GTI in developing the baseline and field trial monitoring plans. GTI will set up field trial instrument package at the field site and carry out baseline monitoring of the steam dryer drum to be replaced. The team will also conduct the following activities under the task:

GTI will evaluate the baseline information along with BPS
- Additional analysis provided by WMU.
BPS to remove existing steam dryer drum; prepare the site and install the gas-fired dryer unit and the external combustion system
Gas-fired drying drum to be shaken down by GTI and project team; unit to be placed on line and made operational.
GTI to carry out field trial monitoring
GTI to process all data, baseline and field trial and analyze same
- WMU to provide independent analysis
GTI to prepare a final technical report to include:
- Benefits (energy, environmental)
- Productivity improvements
- Technical conclusions
- Dissemination and marketing plan for industry
- Cost/benefit analysis and recommendations (Final Deliverable).
