Delimitation for reduction of the dust emissions for a cooler for cooling hot bulk material

A cooler for cooling hot bulk material, comprising:

• a grate surface configured for supporting the hot bulk material for treatment;
• a first cooler wall and an opposing second cooler wall spaced apart to delimit the grate surface between the first and second cooler walls;
• a feeding-in point for feeding the hot bulk material to the grate surface;
• a first region that extends over between 20% and 30% of the grate surface, wherein the first region comprises the feeding-in point;
• a positionally fixed first cover over the first region;
• a second region that is upwardly open and is situated between the first region and a third region;
• an extraction point for the cooled bulk material;
• the third region that extends over at least 10% to 20% of the grate surface, wherein the third region comprises the extraction point;
• a positionally fixed third cover over the third region;
• a delimitation at the second region comprised of a positionally fixed first wall that comprises a plurality of individual segments, and a positionally fixed second wall comprising a plurality of individual segments and spaced from the positionally fixed first wall, and the delimitation extends at least over a partial section of the second region;
• a supporting structure on which the positionally fixed first wall and the positionally fixed second wall are suspended, the positionally fixed first wall lies on the first cooler wall or is separated from the first cooler wall by a gap, and the positionally fixed second wall lies on the second cooler wall or is separated from the second cooler wall by a gap;
• and the delimitation additionally has a perforated plate comprising a plurality of individual segments situated between the positionally fixed first wall and the positionally fixed second wall.
