Combustion air is used as the so-called primary air, which is blown through a combustion grate into a fuel bed which rests on it. The cooling effect of the primary air flow is determined by the gap size between the grate rods, or by a given outlet opening and the flow resistance of the primary air through the fuel bed at this point. If the primary air flow is displaced by a liquid slag, which for example blocks the gap or clogs the outlet opening, the relevant grate rod is not substantially cooled.

From C1 publication, a grate rod having a hollow box-shaped cross-sectional shape is known. Two chambers are formed between the upper side and the lower side of the grate bar via a central rib.
The air introduced from the rear flows through the chamber, passes through the slit nozzle and flows out into the combustion chamber in front of the grate rod. Even in this cooling method, since there is a risk of clogging of the slit nozzle, air does not flow out from the grate rod, and therefore the grate rod cannot be cooled.

冷却作用が低くなる。Further, from EPO924464A1 is known a cooling type grate rod provided with a coil tube through which air flows, which is wound in a meandering manner on a lower side of the grate rod by a method not described in detail. The flow through the coiled tube causes air to flow out of the grate rod through an outlet opening located below the grate rod and laterally. If the coil tube is not fully fixed, the heat transfer from the grate rod to the cooling air is significantly hindered by the coil tube. The coil tube laid in a meandering shape,
In principle it causes an asymmetric temperature distribution in the grate rod.
As a result, the grate rods with undesirable gap formation between the juxtaposed grate rods contract. Air exiting the side outlet openings enters the grate rod behind it on only one side, which again causes an asymmetric temperature distribution in the relevant grate rod. By having only one passage flow through, the cooling air quantity is very limited, which leads to a low cooling effect.
