Abstract
A fire grate is adapted to support a combustible mass. It is inclined longitudinally from a feed end at which it receives the combustible mass to a discharge end. It comprises a plurality of elements disposed in transverse rows alternately fixed and mobile. Each element is rectangular in plan and has a top side and a bottom side, openings by means of which the top side and the bottom side communicate, and a generally transversely oriented front protuberance on the top side in the vicinity of its transverse edge at the feed end. All the openings are in a dorsal surface of the front protuberance facing the discharge end.
Claims21
A furnace construction for a combustible mass, said furnace construction comprising a fire grate for supporting a combustible mass during burning of such combustible mass, said fire grate being inclined downwardly longitudinally from a combustible mass feed end to a discharge end, said fire grate including a plurality of like elements disposed in plural transverse rows, support means mounting said transverse rows alternatingly in fixed and longitudinally mobile positions, each of said elements being rectangular in plan and having top and bottom sides, said top side having a generally planar major surface portion inclined downwardly longitudinally towards said fire grate discharge end, said element having a feed end transverse edge and a discharge end transverse edge, a generally transversely oriented front protuberance on said top side adjacent said feed end transverse edge, said front protuberance having a dorsal surface generally facing said fire grate discharge end, and openings for combustion supporting air through said dorsal surface from said bottom side to said top side, said openings extending generally horizontally as opposed to vertically.
A fire grate for supporting a combustible mass during combustion thereof, the fire grate being inclined downwardly longitudinally from a combustion mass feed end to a discharge end, the fire grate including a plurality of like elements disposed in plural transverse rows, support means mounting said transverse rows alternatingly in fixed and longitudinally mobile positions, each of said elements being rectangular in plan and having top and bottom sides, said top side having a generally planar major surface portion inclined downwardly longitudinally towards said fire grate discharge end, said element having a feed end transverse edge and discharge end transverse edge, said feed end transverse edge being engageable with the planar surface portion of an immediately upstream and subjacent one of said elements, a generally transversely oriented front protuberance on said top side adjacent said feed end transverse edge, said front protuberance having a dorsal surface generally facing said fire grate discharge end, openings for combustion supporting air, said openings all extending through said dorsal surface from said bottom side to said top side, openings angling upwards but lying closer to the horizontal direction than the vertical direction.
