    摘要： A glutinous or highly viscous substance is burnt within a hot fluidised bed of inert material by first coating a particulate material with the substance and then introducing the coated particles into the bed for combustion. After the coating has been combusted the particles can be removed from the bed for further coating with the substance. This method of combustion affords an effective way of dealing with glutinous or highly viscous substances, e.g. waste materials, which otherwise would be unsuitable for burning in a fluidised bed.

    摘要： A rotary cutter head for a mineral mining machine, has a hub for mounting on a driven machine shaft, a drum secured around the hub and cutter tool holders secured around the drum, the head being provided with a plurality of angularly arranged chambers for dust suppression fluid, each extending axially along the inner periphery of the drum and arranged to feed fluid from a distribution unit adjacent to the hub towards the cutting zone of the head.

    摘要： An underframe for a longwall mineral mining machine has a hollow deck which forms a guide duct for dust laden air which is drawn from the region around the cutter head and passed via the guide duct to a layer of filter material which removes the dust before the relatively dust free air is discharged into the mine atmosphere.
