Statement of Work (SOW)

Project: Incinerator 5 Refractory Demolition and Reline

GENERAL INFORMATION

1.0 Scope of Work: The requirement is for incinerator 5 demolition and relining of the refractory. The new refractory must match the existing dimensions once the work has been completed. The current dimensions are shown in the attached drawings.

The dimensions must not change to remain in compliance with our air quality permit from the Iowa Department of Natural Resources.

2.0 Background: The United State Department of Agriculture, USDA, Agriculture

Research Service, ARS, located in Ames, Iowa has a requirement for removal and replacement of refractory in Incinerator 5. The USDA operates this controlled air incinerator at a rate of 500 pounds per hour. The refractory in this incinerator is exhibiting cracking and separation in several areas in the primary and secondary chambers. This incinerator was upgraded in 2010 and the refractory in the primary and secondary chambers were relined at that time. There have been several areas of refractory that has been patched sense that time. The incinerator will now require the demolition and replacement of all refractories below the charge door and below the stack.

CONTRACTOR REQUIREMENTS

3.0 Technical Requirements/Tasks: All new construction shall conform to standards as called out in the drawings attached. Contractor shall prepare the primary and secondary chambers for refractory removal and installation. This will include the removal and reinstall blowers, burners, and thermocouples as needed. Once the preparation is completed the contractor shall remove existing refractory, insulating brick and temperature resistant insulation and dispose of it properly. After the refractory, insulating brick and insulation has been removed the contractor shall check walls for any heat damage and notify COR of any damage. Any damage found shall be repair as needed by the contractor. The contractor shall check interior of the incinerator for broken anchors and prepare primary and secondary chambers for new anchors and install anchors. Contractor shall then install temperature resistant ceramic fiber insulation and the 2600 IFB insulating brick to the walls.

Contractor shall then apply new refractory rated for 3000F to the interior of Incinerator 5 primary and secondary chambers. Contractor shall complete the installation of the refractory so that it conforms to standards as called out in the drawings attached. The contractor will be on site for required cure process.

The contractor shall then restore work area to pre-work conditions.

4.0 Government Furnished: The Government shall Lock Out Tag Out incinerator 5 isolating all power supplies to incinerator 5 including electric, gas, air and hydraulic. Contractor shall Lock Out Tag Out all sources of energy to the incinerator in addition to the USDA. The Government shall furnish water for cleaning and preparation work, electrical power, and compressed air at 95-100psi.

The Government will operate the incinerator to assist the contractor in the contractor’s task n curing the new refractory to the temperature as recommended by the manufacturer.
