Coal mining waste disposal combustion plant - has fluidised granular beds for drying waste before combustion

摘要

The plant for treatment of waste material containing fuel and moisture converts this waste into another material of low density. The waste material is fed into a fluidised bed for drying. The fluidised bed is maintained with hot combustion products rising from combustion layer below. The waste falls subsequently into combustion layer. The waste material which consists of coal mining residues, can be sprayed into fluidised bed or combustion layer. Two superposed fluidised beds consisting of granular material can be used.
