Clyde Bergemann wins dry ash deal at Taiwan coal plant

Energy technology company Clyde Bergemann has won a contract one of the largest coal-fired power stations in the world.

The company will work at Taichung power plant in Taiwan to convert wet bottom ash handling to an eco-friendly dry ash system using its DRYCON technology.

With an installed capacity of 10 x 550à‚ MW, Taichung is amongst the five biggest coal plants in the world. Six of the older units so far reclaim their ash by-products by mixing the ash with water to form slurry, which is then further conveyed to ash retention ponds.

The ever-growing need to conserve water due to stricter land usage regulations made plant owner Taiwan Power consider a conversion to dry ash handling.

Germany’s Clyde Bergemann GmbH won the order to supply its dry ash conveying solution to the first of six units. Clyde Bergemann’s solution consists of a fabric compensator, a transition hopper with isolating gates and the DRYCON steel plate conveyor.

DRYCON automatically transports and cools the bottom ash by drawing ambient air along the conveyor and effectively transferring heat back into the boiler. The fully enclosed system ” with a width of 1.8 metres and a total conveying length of 42 metres ” eliminates the use and treatment of water.
