  • Patent number: 4596233
    Abstract: Solid fuel combustion equipment in the form of a grate assembly comprises longitudinally extending support elements on which are mounted laterally orientated grate bars. The support elements are pivotable about their horizontal axes and are provided with sealing means at their adjacent margins to effect a seal to prevent in use passage of air when the elements are horizontally aligned. De-ashing of the grate assembly in use is achieved by tipping the support elements, whereupon ash falls to a receiving area when it is removed.
