Combustion of waste materials produced by coal extractionFunded under: ECSC-COALRES 3C
The coal industry produces a large amount of materials which are difficult to valorize. The material is characterized by fine particle size, high water and ash contents. The materials from coal-washery plants are washed out and settle out in ponds. This type of pollution is destructive as demonstrated by a Belgium coal extraction company which now must manage and rehabilitate hundreds of unservicable hectares since they stopped mining in 1989. This project investigates the possibility of combusting these high ash content materials directly into a boiler. This conforms to ECSC conventions which aim to de-ash and de-sulphurize materials through a selective agglomeration process prior to burning. However for this process to be effective, plants must be located near the production site to avoid transport costs and should be scaled according to available coal residues.
