Pre-Proposal date: November 29, 2017 Pre-Proposal location: 575 W. Cameron St. Chapel Hill, NC (2nd Floor conference room) The University of North Carolina operates two (2) 250,000 pounds per hour Circulating Fluidized Bed boilers permitted to burn coal, biomass, natural gas and number 2 oil. The primary fuel is Eastern Bituminous Coal. Limestone is added in the combustion chamber of each boiler to control SOx emissions, and baghouses collect particulate downstream of the boilers. Due to new permit requirements that take effect in May 2019, the University desires to install a dry sorbent injection system to control HCl gas in the boiler exhaust. This project will address that need including a sorbent silo sized to store one month's supply of sorbent when both boilers are operating at maximum load. The system will include all blowers, pumps, electrical gear, structural supports, platforms and any miscellaneous equipment and appurtenances necessary to form a complete functioning system, including any equipment necessary for loading sorbent into the silo and any specialized maintenance tools. The project is located in an area where noise attenuation is essential. The scope will include designing the system and any structural supports, providing the equipment, and constructing the system. The design shall incorporate the new electrical demand with the overall electrical primary and alternate infrastructure. This electrical demand assessment shall include one Variable Frequency Drive for one Cooling Tower Fan to help manage the load on the electrical primary and alternate infrastructure. The design shall also include the new instrument air demand with the existing instrument air infrastructure. The team shall determine if more storage and/or air compressor capacity is required for the new equipment. The scope includes providing assistance in the commissioning of the system, providing system documentation including system descriptions, operations manuals, P&ID's, loop sheets, and as-built construction drawings. The scope shall include integration of the system controls with the existing plant DCS (Emerson Ovation). The design shall comply with all UNC and SCO design standards. The project will utilize the design build method of delivery as defined in NCGS 143-128.1A. For additional information, please contact the project manager via email:
