US 4,610,209 A · Grate bar and grate tumbler for the tumbler grate of, e.g., a trash incineration installation or the like

Abstract

The invention concerns a grate bar for a grate tumbler of a tumbler grate of a trash incineration installation or similar combustion facility with a base rod showing an outer rod surface and an inner rod surface, as well as side surfaces, a head surface and a foot surface, the cross-section form being T-shaped with a cross rod (15). The invention also concerns a grate tumbler for the tumbler grate of a trash incineration installation or the like with a hollow shaft and a cylindrical carrier construction, with grate-bar carriers resting upon the carrier construction and grate bars mounted upon the carriers, while the grate bars are mounted upon the grate bar carriers (8) in such fashion that the slit (25) between adjacent grate bars (11) is no greater than 1 mm in width on the combustion-chamber side.

In a grate tumbler for the tumbler grate of a trash incineration installation or the like, having a long axis with a hollow shaft and a cylindrical carrier construction, with grate-bar carriers resting upon the carrier construction upon which grate bars are mounted, the improvement comprising:

the grate bars being mounted upon the grate-bar carriers and comprising a base rod having an outer rod surface facing a combustion chamber of the incineration facility, an inner rod surface, side surfaces, a head surface, and a foot surface;
each grate bar having a cross rod located at an end of the base rod in proximate location to the combustion chamber so that the cross-section form of the grate bar is a T-shape;
and
adjacent ones of said grate bars being mounted in parallel spaced apart relation so as to define a slit between said cross rods of adjoining grate bars, the slit between adjoining grate bars being not more than substantially 2 mm wide on the combustion-chamber side.

1 more element

An elongate grate bar for use in a tumbler grate located in a combustion chamber of an incinerator and having a plurality of such grate bars mounted in spaced-apart parallel juxtaposition so as to define a continuous elongated slit between adjacent grate bars, comprising:

an elongated base rod having an outer rod side facing the combustion chamber, and also having an inner rod surface and side surfaces along the length of the elongated base rod;
said outer rod side comprising an elongated cross rod joined to the base rod so that the cross section form along the length of the elongate grate bar is a continuous T-shape;
said cross rod having an outer rod surface facing the combustion chamber, so that the contiuous elongated slit between adjacent grate bars is defined between the elongated cross rods of said grate bars;
said outer rod surface having outer corners extending lengthwise and facing the combustion chamber;
and
said cross rod having flat side-cant surfaces positioned proximately at a right angle to said outer corners and having inner corners running parallel to each other.
