KOCH Pipe Conveyor® for World`s Largest Power Plant Desulfurization Sys
It slices through the power plant, rises up to a 20 m high dam, then plummets back down, cuts 90° and 70° curves past a coal stockpile and then traces gentle arcs through the verdant, lush landscape: On this demanding route, KOCH is building a 1,366-meter-long double Pipe Conveyor. The transport system is part of the world`s largest CFB FGD power plant desulfurization system, which is being erected by Lentjes GmbH. The system will reduce the 3x305 MW power station`s SO2 emissions from 4200 mg/Nm3 to below 350 or even 200 mg/Nm3. Up to 280 t of power station residues will be loaded from the power station mixer onto the redundantly designed double conveyor system (300 mm diameter) and then transported to the landfill. The material – a moistened, fast-setting paste made up of CFB FGD product, flyash, water and cement – is hard to handle: It begins setting during transport, so the chutes, belt and transport speed all have to be carefully selected to prevent the material from caking. The KOCH Pipe Conveyor not only seals the material off from weathering effects, but it also keeps the transport route clean in an extremely attractive countryside: With its enclosed belt tube and lack of transfer points along the entire route, it provides optimum protection – for the transported material and the environment alike.
