Dry Bottom Ash Handling from Clyde Bergemann Senior

Clyde Bergemann Materials Handling Ltd (CBM), Doncaster, England was awarded the contract for dry bottom ash handling and pneumatic conveying technology at the Kosice power plant in Slovakia. The plant, operated by Teplaren Kosice a.s. (Teko), is undergoing a rehabilitation project to upgrade two 150 MW coal-fired boilers.

CBM received the order for the materials handling technologies from Istroenergo Group, a.s. (IEG), Slovakia who are heading up the refurbishment project for Teko. Included in CBM's project scope is the design, supply, delivery and commissioning of dry bottom ash conveying systems, DRYCON™, including hopper and jaw crushers. CBM will also supply densephase pneumatic conveying technology to convey ash from the economisers and air preheaters.

The decision for the plant refurbishment was to upgrade existing technologies to increase plant efficiency and also to reduce aspects such as water treatment which were proving costly in the running of the plant. In order to do so, a decision was made to source dry bottom ash handling technology to replace the existing wet hydraulic conveying systems.

Clyde Bergemann's DRYCON™ technology which is designed to eliminate the use of water as well as returning heat energy to the boiler resulting in lower coal usage, was considered one of the preferred options for the dry bottom ash system. The contract was awarded to CBM in January 2011 and is scheduled to be operational the first quarter of 2012.

Craig Buckley, General Sales Manager of CBM, comments: "This is a tremendous achievement that is well overdue and a great start to the new year. This success comes from a culmination of efforts over the past 5 years and should send strong and positive signals to the industry regarding our position in the market to provide dry bottom ash technologies."
