Abstract
Ein Roststab weist einen Roststabkopf, zwei Seitenwände, eine Lauffläche hinter dem Roststabkopf zwischen den Seitenwänden und eine zwischen den Seitenwänden unter der Lauffläche liegende Unterseite auf. Eine Ausnehmung in einer Seitenwand zwischen Lauffläche und Unterseite bildet mindestens einen Luftschlitz der nur an einer Seitenwand und nicht in deren gegenüberliegender Seitenwand angeordnet ist.Bei einer Roststabanordnung mit mehreren Roststäben mit jeweils einer Lauffläche und einem Roststabkopf, bei der ein oberer Roststab mit seinem Roststabkopf relativ zu einem unteren Roststab derart beweglich angeordnet ist, dass der Roststabkopf über einen vorderen und einen hinteren Bereich der Lauffläche des Roststabes gleiten kann, weist die Lauffläche im vorderen und im hinteren Bereich Luftschlitze auf und der Roststabkopf ist relativ zu diesen Luftschlitzen derart verschiebbar, dass der Öffnungsquerschnitt aller Lüftungsschlitze konstant bleibt.A grate bar has a grate bar head, two sidewalls, a tread behind the grate bar head between the sidewalls, and a bottom underlying the tread between the sidewalls. A recess in a side wall between the running surface and the underside forms at least one air slot which is only arranged on one side wall and not in the opposite side wall is movably arranged in relation to a lower grate bar in such a way that the grate bar head can slide over a front and a rear area of the running surface of the grate bar, the running surface has air slots in the front and rear area and the grate bar head can be displaced relative to these air slots in such a way that the Opening cross-section of all ventilation slots remains constant.
