44 -- SUPPLY BOILER FOR DEMONSTRATION OF LOW EMISSION CYCLONIC COMBUSTION SOL DACA88-97-R-0007 DUE 050297 POC Contract Specialist Anne Cox (217) 352-6511, extension 7413 Contracting Officer Deloras Adamson (217) 373-7297 (Site Code DACA88) The U.S. Army Construction Engineering Research Laboratories (USACERL) require one (1) factory-assembled, package type boiler with natural gas burner, steam drum, economizer, controls, and forced draft fan mounted to the maximum practical extent as an integral unit on a steel base. An option is included to provide a second boiler with the aforementioned requirements. Additionally, there are two (2) options for providing a dual fuel burner (natural gas and no. 2 fuel oil) for each boiler. The boiler(s) shall be used for a demonstration of new technology on low emission cyclonic combustion which occurs in two stages. In the first stage, fuel and air are injected tangentially at high velocity into a cylindrical horizontal 100% watertube-walled combustion chamber. The combustion gases are cooled by heat transfer to the watertubes and by steam injection. In the second stage, more air is introduced to complete combustion. The modified commercial burner required shall use this cyclonic combustion. The boiler(s) shall be capable of continuously providing steam at a maximum flow of 34,000 and a minimum of 4,250 pounds per hour. While firing natural gas and using steam injection at 100% maximum continuous rating (MCR), boiler efficiency shall not be less than 82% and nitrogen oxide (NOx) emissions shall not be more than thirty (30) parts per million (ppm). The boiler(s) shall be delivered to two (2) separate Army bases within Continental U.S. Installation shall not be required under this contract. A warranty against defective design, workmanship, material, or performance for a period of one (1) year from the date of the successful completion of the Government's acceptance test for the boiler(s) shall be included. The Government requires delivery of the initial boiler approximately eight (8) months after award of the contract. Request for Proposal (RFP) No. DACA88-97-R-0007 will be issued on or about 11 April 1997 with the closing date on or about 2 May 97. Offerors shall have at least two (2) boilers in successful service for a minimum of two (2) years prior to the closing date of the solicitation. Award will be made to the responsible offeror who provides the lowest overall price to the Government and demonstrates the capability to meet all the requirements described in the solicitation, including the past performance requirement described above, as well as, the Government's delivery schedule. Submissions shall be in accordance with the RFP, and all qualified sources may apply. Multiple awards will not be made under this solicitation. Requests for copies of this solicitation shall be made in writing and addressed to USACERL, Attn: Contracts Office, PO Box 9005, Champaign, IL (0084)
