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 circuit arrangement for voltage testing and partial discharge capture in a single-phase or multi-phase medium-voltage or high-voltage installation includes one or more conductor signal inputs that are couplable to respective capacitive coupling electrodes that are coupled to respective conductors of the installation, a voltage testing unit coupled to the relevant conductor signal input and configured for threshold-based voltage state capture, a partial discharge detector unit, and an energy supply for the partial discharge detector unit with a first energy supply circuit for supplying energy from the relevant conductor signal input and/or with a second energy supply circuit for supplying energy from the relevant conductor signal input. An input side of the partial discharge detector circuit is couplable via a partial discharge connection path to an earth side of an installation system capacitance that is electrically parallel to the capacitive coupling electrode.

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 method for the combined pump water pressure-compressed air energy storage at a constant turbine water pressure, the energy to be stored is used to pump a liquid medium into a pressure vessel such that a rising level of medium compresses the gas contained in the pressure vessel through a connecting conduit and presses said gas into a compressed gas tank, the conduit being shut using a check valve such that the energy is stored in the compressed gas.
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: 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: 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.
