  • Slagging rotary kiln
    Patent number: 5238401
    Abstract: An improved kiln wherein a smile shaped oil cooled refractory support is shortened so its distal end is adjacent the outside end of a front nose ring on a rotatable kiln drum, the nose ring being extended radially inwardly to shield the distal end of the smile shaped support from radiant energy from the kiln drum and direct combustion air over the distal end of the smile shaped support to prevent thermally induced stress cracking and substantially reduce the amount of partially burned material that spills over the front nose ring.
