Abrégé
A grate bar has a grate bar head, two side walls, a running surface behind the head and between the side walls and an underside disposed below the surface and between the side walls. A recess in one side wall forms an air slot between the surface and underside and is arranged only on one side wall, not in its opposite side wall. In a grate bar arrangement including multiple grate bars, each including a running surface and a grate bar head, in which an upper grate bar with grate bar head is moveably arranged relative to a lower grate bar so that the head may slide over front and rear grate bar running surface areas, the running surface has air slots in the front and rear areas and the head is displaceable relative to these slots so that the opening cross section of all slots remains constant.

Abrégé
A device for generating pressure waves of high amplitude, in particular for boiler cleaning, has a pressure-resistant container (21, 40) with a combustion chamber (121) inserted therein, which can be filled with a flowable burn-off material via supply lines. The pressure-resistant container has a discharge opening (306) for the directional discharge of gas pressure generated by ignition of the combustible material. A piston (70) closes the discharge opening, can release it for directional discharge and can be pushed back into the initial position by a spring device. With respect to its longitudinal direction (305), the seat of the piston (70) has a piston surface (302) inclined obliquely to the discharge opening (306), which is arranged opposite a housing surface (303) also inclined obliquely to the discharge opening (306), the housing surface (303) opening opposite the piston surface (302) at an angle (304) oriented towards the discharge opening (306) from a closure line (65) oriented perpendicularly to the piston direction (90).
