A fire grate has tensioning devices (3) inserted in recesses (2) of an oven wall (1), with each device acting upon one grate side plate. The tensioning device (3) includes a cylinder (4) inserted into the oven wall, a hollow piston (7) guided therein and a spring (26), which can be adjusted in its tension. The grate side plate has a carrying plate (12) directly fastened to the piston bottom (10) with a grate border plate (13) suspended, or hanging, on the carrying plate (12). The piston (7) has diameter and length dimensions such that it can support and guide the grate side plate without further guiding devices. Neighboring pistons (7) are connected flexibly to each other by guiding bars (36), so that the pistons (7) can influence each other reciprocally. An upper edge of the grate side plate, particularly the grate border plate (13), has a flange (17) extending toward the oven wall. The flange (17) sealingly engages an elastical seal (19), fastened onto the oven wall. An additional covering ledge (21) covers the flange (17) and includes a shaped part or angle (22) which bounds a hollow space (23) between these two parts, just like a labyrinth seal.

The arrangement for treating combustion residues of a combustion installation comprises an ash discharger into which opens a fall shaft, into which the solid combustion residues fall from a furnace grate. The ash is conveyed from the ash discharger into the discharge shaft via a diagonally ascending push-out chute by a push-out ram whose operating rate is so adjusted that the ash is piled up in the fall shaft in a tower formation reaching above the liquid level. Fresh water or a chemical is introduced into the discharge shaft via an inlet. The ash discharger water present in the ash discharger and charged with fine particles is drained into a hermetically sealed settling tank via a draw-off duct. Ash discharger water, with which a chemical can be mixed via another line, is fed from the upper region of the settling tank by a pump via a return line to spray nozzles which are arranged in the upper region of the fall shaft. Ash discharger water which is enriched with solids particles is drawn off from the bottom of the settling tank via another pump which is arranged in an outlet line proceeding from the settling tank. This is effected at a rate such that solids particles having a diameter of up to 2 mm are carried away with the ash discharger water which is drawn off through the draw-off duct.

In a process that is used to regulate the quantity of a processing medium at is used to reduce the nitrogen monoxide content in the exhaust gases generated by combustion processes, in which the quantity that is used is regulated as a function of the nitrogen monoxide content, a processing medium blow-by nominal value (8) that is changed as a function of the nitrogen monoxide content value (3) measured in the exhaust gas (2) is used in addition to a pre-set nitrogen monoxide nominal value (7) .

The secondary air nozzle for furnaces has a curved base body which is provided with pins for holding a ceramic protective casing. A protective strip which projects radially from the base body is arranged along the longest line of curvature proceeding from the nozzle opening until beyond the curved part, its radial dimension corresponding at least to the thickness of the ceramic protective casing. The protective strip is constructed as a rib which projects radially from the base body and is outfitted with pins for supporting the ceramic body.

A process and apparatus for extracting water from ash that has been quenched in water bath of an ash discharger and which is expelled from the water bath by means of a discharge ram through a discharge chute includes an improvement wherein the discharge chute of the ash discharger is caused to vibrate. The vibration is provided by a vibration generator, particularly of the unbalanced type.

In order to recover or dispose of ammonia or ammonia compounds from mixtures of dust that occur during combustion processes, during subsequent gas cooling, or during subsequent gas scrubbing, the dust that is created is mixed in batches with water in a closed system at a temperature that is lower or equal to the temperature at which the dust leaves the combustion, cooling or scrubbing process, and the resulting vapors are drawn off in a vacuum.

The secondary air jets (11) that are arranged within the combustion space (5) consist of an outer casing (12), an inner casing (13), and a flange (14) that connects the two casings to each other, the flange (14) crossing the inner casing (13) and being rigidly connected with this, whereas the outer casing (12) is so connected to the flange that is of greater diameter than the outer casing (12) that slot-type jets (15) are left between the face side of the outer casing (12) and the flange (14), these jets making it possible to expel air parallel to the defining wall and essentially perpendicular to the axis of the jets.

A feed device comprises a filling hopper, a feed chute and a plurality of feeding pistons arranged adjacent to one another on a feed table, each feeding piston carrying at least one retaining and compression body in the area of its front end. The retaining and compression bodies can be constructed as flat or cubic bodies, wherein the surface configuration can be shaped in the manner of a rectangle, triangle, arc, trapezoid, pyramid or cone frustum.

The grate of an industrial furnace is assembled of elongated grate bars which form rows of neighboring grate bars and the grate bars of neighboring rows partially overlap each other. Each grate bar has a top wall, a front end wall and two sidewalls, and such walls define an air-admitting passage having a portion in one or more hollow upward extensions of the top wall close to the front end wall. The extensions have transverse openings which discharge air from the respective portions of the passages into the surrounding atmosphere, namely into fuel which is deposited on the grate. The openings of each extension are located in planes which are inclined to the longitudinal direction of the corresponding top walls through angles of 80-90 degrees, and such openings can be inclined forwardly, rearwardly, downwardly or upwardly. If the grate bars have top walls with several extensions, the openings in the extensions of each grate bar can be staggered relative to each other. This also applies for the openings in the extension of neighboring grate bars. The neighboring grate bars are coupled to each other against sliding movement relative to one another.
