Clyde Bergemann Power Group Americas won a contract to supply both the engineering and equipment to convert the existing wet bottom ash removal system of Seminole Electric’s two 650 MW coal fired units located in Palatka, Fla. to a dry system utilizing its Drycon technology. The contract will be executed by Clyde Bergemann Delta Ducon, the business unit for ash handling with installation performed by Roberts and Schaefer.
The dry bottom ash systems will replace the plant’s existing wet systems and will reduce maintenance costs and allow the sale of the ash. Seminole’s selection of the system was centered on its design as well as its ability to improve the plant’s heat rate through a reduction of loss of ignition. Included in Clyde Bergemann’s project scope is the design, supply, delivery and commissioning of two complete dry bottom ash conveying systems, including ash hoppers and jaw crushers.
This award marks the first utilization of the Drycon technology in North America. It is also one of the first conversions of a wet to a completely dry bottom ash system in almost 20 years in North America.
The contract was awarded in March 2011 and the equipment installation is scheduled during a normal boiler outage in spring and fall 2012.
