Furnish Boiler Tube Replacement as Specified

To remove existing boiler tubes and install 220 new boiler tubes each in two (2) A.B.C.O. Heat Recovery Steam Generators (HRSG) as specified and shown herein. The water tube HRSG boilers are configured as shown on the attached drawing. Heat recovery is from flue gas produced through the incineration of Solid Waste. Flue gas particulate deposits on the gas side of the boiler tubes and gas side boiler structure in the form of “slag”. This slag contains lead, cadmium and possibly arsenic. The Owner will clean the boiler by means of sandblasting. However, there may be residual slag in the boiler gas side and the Contractor should be prepared to provide proper PPE for his employees. The Owner has installed a central “breathing” air system, which may be utilized by the Contractor. Tubes to be replaced are rows 8 through 17 (10 rows total, 22 tubes per row) on the hot gas (east side) inlet side of the boiler. The HRSG boilers have removable panels on one side only (approximately 13 feet high by 8 feet wide) for easy access to the tubes. Panels will be opened by the Owner.
