Abstract: 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.

Abstract: A method operates a furnace unit with a feed chute and a camera for capturing an image of the surface of the chute. The chute includes a slide on which material flows to a grate, and the coverage of the chute and in particular of the slide with material, the burning bed thickness and the burnout zone are determined by an image evaluation.

Abstract: A method includes producing an arrangement of grate bars for supporting fuel that is burned in an incinerator or other furnace device. The method includes positioning a pair of grate bars in adjacent side by side relation and with the respective upper sides that are configured to support the fuel, in generally aligned relation. The method further includes after positioning the grate bars, manipulating a fastener through respective recesses that extend in the grate bars, so that the grate bars are held in operative connection and in pressed together relation by the fastener. The method further includes subsequent to the fastener manipulation step, covering the recesses with at least one cover, such that the fastener is rendered inaccessible through the upper sides of the grate bars.

Abstract: A control device (1) for an electrosurgical instrument (2), in particular a high-frequency sealing instrument, including a fixed handle part (3), a movable handle part (4), an activation element (5) for activating a current flow, in particular a first type, preferably a sealing current, wherein the activation element (5) is or can be adjusted between a deactivation position and at least one activation position when the movable handle part (4) is actuated, wherein, when the movable handle part (4) is actuated, the activation element (5) is or can be adjusted about an axis of rotation (7).

Abstract: The invention relates to a device for an electrosurgical instrument, comprising a coupling unit, said coupling unit having a fluid line connection and a current line connection which are designed to carry fluid and current, via a fluid line of the device and at least one current line of the device, between a higher-level assembly and a distal end of the device and a filter, the filter being provided separately from the coupling unit in a fluid flow path of the fluid line, such that the fluid flowing through the fluid line flows through the filter.

Abstract: The invention generally relates to intermediate layers (shim-type stacked foils/films) as adjusting elements for mechanical structures.

Abstract: A cleaning hose conveying module is proposed for the simple and quick cleaning of flue gas tubes, with which the cleaning hose can be conveyed from a hose store into a hose guide. A hose cleaning means is formed by a rinsing and drying unit for a hose after its withdrawal from the flue gas tube.

Abstract: A power-generation system having a combined heat and power plant and a fermentation plant has an electrolysis plant, which is connected by lines to both the combined heat and power plant and to the fermentation plant. This arrangement enables a method in which heat from a combined heat and power plant can be used for a fermentation plant and additionally heat from an electrolysis plant can be used for the fermentation plant, whilst the oxygen from the electrolysis plant is used for the combined heat and power plant.

Abstract: In a method for the combustion management in firing installations, in which a primary combustion gas quantity is conveyed through the fuel into a primary combustion area, part of the waste gas flow is extracted in the rear grate area and returned to the combustion process in the form of internal recirculation gas. In this case, no secondary combustion air is supplied between the grate and the supply of the internal recirculation gas. A firing installation for carrying out this method features nozzles above the firing grate such that no air supply is arranged between the firing grate and the nozzles.

Abstract: In a method for protecting heat exchanger pipe in boiler systems having at least one heat exchanger pipe, which is surrounded by a ceramic component, into which flue gas is directed from at least two opposite sides, gas is introduced between the heat exchanger pipe and the ceramic component.

Abstract: A special distribution of nozzles in the flue gas outlet and their alignment make it possible to guide the flue gas along a wavy line. The addition of combustion air for primary air and secondary air can be variably distributed during operation of the combustion plant, for example so as to also keep the burnout per unit of time constant while maintaining a constant combustion air ratio.
