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.
Claims17
Solid fuel combustion equipment including a grate assembly having at least two longitudinally extending support elements adapted to pivot about the longitudinal axes thereof, a plurality of grate bars arranged on the support elements, and sealing means attachable to each longitudinal side of each support element such that in use when the support elements are in a horizontal position, the sealing means cooperate to provide a resilient seal between adjacent support elements to prevent the passage of gas.
Solid fuel combustion equipment including a grate assembly having four longitudinally extending support elements arranged side by side and adapted to pivot about the longitudinal axes thereof, first sealing means on adjacent parts of the two centre support elements comprising tubular members resiliently mounted on the support elements and adapted to abut and seal the two centre support elements, and second sealing means on adjacent parts of the two centre support elements and the two side support elements, the second sealing means comprising a plate member resiliently mounted on one support element and a resiliently mounted abutment on the other support element presenting a flat surface to complement and seal with the plate member.
Solid fuel combustion equipment including a grate assembly having at least two longitudinally extending support elements adapted to pivot about the longitudinal axes thereof, a plurality of grate bars arranged on the support elements, and sealing means attributable to each longitudinal side of each support element such that in use when the support elements are in a horizontal position, the sealing means cooperate to provide a seal between adjacent support elements to prevent the passage of gas, the sealing means comprising tubular members a part of the cirfcumferential surface of which presents arcuate sealing surfaces, the tubular members having mounting arms for attachment to the support elements.
