Chadds Ford, Pennsylvania, USA, December 15th, 2016 – Bridgestone Associates, Ltd (www.brdgstn.com) recently completed the detailed design of an 11 MW Combined Heat and Power (CHP) plant for Bryan Power Generation Solutions Group, LLC. (www.bryan-power.com) of Colorado Springs, Colorado. The CHP plant is being installed by a food manufacturing client of Bryan Power at a facility in Cedar Rapids, Iowa and is based on pre-owned equipment purchased and re-sold by Bryan Power.
The CHP plant includes two Solar T60 natural gas fired combustion turbines with two Rentech Heat Recovery Steam Generators (HRSGs). This equipment had been installed in 2004 at the Naval Station Great Lakes in North Chicago, IL. It had operated there from 2005 until decommissioned by the Navy in 2014. Bryan Power purchased the complete CHP plant, including all auxiliary equipment, pipework, conduit, controls, structural steelwork, and even floor gratings, and then salvaged, removed and transported it to Cedar Rapids, IA. Once installed and operational again it will provide approximately 11 MW of electricity and 90,000 lb/hr of process steam for food manufacturing.
Bridgestone’s design was based on re-installing the complete CHP plant in the same configuration as before with allowance made to add a third Solar T60 combustion turbine and a 2 MW back pressure steam turbine. This meant developing a design that maximized the re-use of all of the components of the old plant while designing a building and interconnections to meet the local client’s specific requirements. Bridgestone completed the detailed design including the structural and detailed design of the new 100’ x 80’ x 50’ building with two 125’ stacks extending from the building roof; structural and detailed design of a gas compressor building; design of a pedestrian interconnecting bridge between the new building and the existing boiler house; all piping, ductwork, mechanical, P&ID, and layout drawings; all interconnecting piping and connections to the existing boiler plant; and a 350 psig steam pipeline approximately 200’ into the food manufacturing plant. Bridgestone also worked with the client’s local electrical contractor on the design and layout of all electrical equipment, conduits and electrical connections.
“This was an interesting but demanding design project requiring careful understanding of the old plant’s design and layout so that the new plant could re-use as many components from the old plant as possible” said Martin Anderson, President of Bridgestone Associates, Ltd. “Given local sub-surface soil conditions, and a vertical stacking configuration of the combustion turbines, HRSGs and exhaust stacks, the structural design was particularly challenging. Adding room for a third combustion turbine compounded these structural issues, but we were able to develop a complete design to accommodate all of the equipment, a third future unit, and a future steam turbine” continued Mr. Anderson. “This has been a great opportunity to continue our work for Bryan Power and to help support their goals of re-engineering and re-using existing CHP and other power generation equipment to save capital costs for their clients.”
