HEARTH GRATE MADE UP OF ELEMENTS ALLOWING IMPROVED CONTROL OF PRIMARY AIR INTAKE

摘要

precisthe invention relates to a hearth gratewith fuel during the fuel mass.tion. the structure according to the invention is homein a longitudinally inclined downwardsend of the fuel supply to the massone end of the discharge, and includesa plurality of similar elements have severaltransverse rows, means of material formingthe transverse rows alternately with)the fixed and movable lengthwise positions.the elements are rectangular in plan and havingthe upper and lower sides of the upper sidea major part of generally planar surfaceinclined lengthwise down tothe end of discharge gate elementwith a transverse end edge foodthe transverse edge and a discharge end.the edge cutting feed is endable to make contact with the flat part of thethe surface of an element immediately upstream.the underlying. the family also includes grida front protrusion oriented generallyon the side adjacent to the transverse topthe transverse edge of the supply end.a dorsal frontal protuberanceusually facing at the end of dischargeof grid and apertures for airthese orifices extending combustion all overdorsal surface from the lower side to sayupper side and forming upward angle, butlocated closer to the horizontal than thevertical.
