36 -- INDUCED DRAFT FANS AND DRIVE SYSTEMS SOL ANG5CQ04-a DUE 042496. Contact Mr. Stephen D. Hoskins, 303/843-2359. The following equipment will be purchased as part of the Chemical Stockpile Disposal Program for the Department of the Army: Equipment required includes induced draft fans, controls, drive systems (including transformers), lube oil systems (if required for fan), interconnecting ducting and expansion joints for four furnace systems. Electrical power will be supplied at 4160V/60Hz. All equipment may be purchased in one package or by two separate packages as follows: 1.) fans, controls, lube oil systems (if required for fan), interconnecting ducting and expansion joints, and required for fan), interconnecting ducting and expansion joints, and 2.) drives (including transformers). Procurement may include options for six (6) additional sites within the continental U.S. The fan/drive assemblies for each furnace system may include one (1) or two (2) units mounted on separate baseplates with interconnecting ducting to provide the required volume and pressure. The number of units (stages) per furnace system will be determined by the fan manufacturer based on the operating conditions. The approximate fan operating conditions are as follows: FAN 101 (INITIAL CONDITIONS): Inlet (ACFM) - 10,800 (max), 2300 (min); density (lb/cu. ft.) - 0.0382 (normal), 0.0364 to 0.0394 (range); inlet temperature (degrees F) - 350 (normal); differential pressure (IN W.C.) - 23.1 (max), 10.9 (min). FAN 101 (FUTURE CONDITIONS): Inlet (ACFM) - 5,750 (max), 1040 (min); density (lb/cu. ft.) - 0.0548 (normal), 0.0391 to 0.0626 (range); inlet temperature (degrees F) - 135 (normal), 350 (max); differential pressure (IN W.C.) - 66.4 (max), 5.4 (min). FAN 102 (INITIAL CONDITIONS): Inlet (ACFM) - 17,100 (max), 2900 (min); density (lb/cu. ft.) - 0.0377 (normal), 0.0380 to 0.0448 (range); inlet temperature (degrees F) - 178 (normal); differential pressure (IN W.C.) - 80.2 (max), 18.6 (min). FAN 102 (FUTURE CONDITIONS): Inlet (ACFM) - 9,000 (max), 1500 (min); density (lb/cu. ft.) - 0.0463 (normal), 0.0442 to 0.0598 (range); inlet temperature (degrees F) - 135 (normal), 170 (max); differential pressure (IN W.C.) - 121.2 (max), 14.5 (min). FAN 103 (INITIAL CONDITIONS): Inlet (ACFM) - 39,500 (max), 3300 (min); density (lb/cu. ft.) - 0.0396 (normal), 0.0396 to 0.0470 (range); inlet temperature (degrees F) - 169 (normal); differential pressure (IN W.C.) - 82.4 (max), 7.4 (min). FAN 103 (FUTURE CONDITIONS): Inlet (ACFM) - 23,300 (max), 1600 (min); density (lb/cu. ft.) - 0.0462 (normal), 0.0445 to 0.0609 (range); inlet temperature (degrees F) - 135 (normal), 164 (max); differential pressure (IN W.C.) - 113.4 (max), 6.2 (min). FAN 104 (INITIAL CONDITIONS): Inlet (ACFM) - 15,700 (max), 3000 (min); density (lb/cu. ft.) - 0.0362 (normal), 0.0362 to 0.0375 (range); inlet temperature (degrees F) - 171 (normal); differential pressure (IN W.C.) - 82.1 (max), 16 (min). FAN 104 (FUTURE CONDITIONS): Inlet (ACFM) - 8,000 (max), 1500 (min); density (lb/cu. ft.) - 0.0435 (normal), 0.0420 to 0.600 (range); inlet temperature (degrees F) - 135 (normal), 170 (max); differential pressure (IN W.C.) - 109.6 (max), 16 (min). Drives are expected to range from 100 to 600 HP. Companies interested in receiving a Request For Proposal Package for either one package or both (please specify) should contact Stephen D. Hoskins at (303) 843-2359 or notify via fax at (303) 843-2150 by April 24, 1996. (080)
