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 gas 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: In order to protect heat exchanger pipes (1) in steam boiler systems, special casing elements (2) made of fiber-reinforced ceramic are proposed. The casing elements prevent or reduce the formation of films and corrosion on the heat exchanger pipes and thus enable higher steam parameters of the boiler system and a correspondingly increased thermal efficiency.

Abstract: A surgical punch has a cartridge for collecting the resected chips cut off in successive punch cuts. The cartridge is a replaceable disposable commodity. The cartridge consists of a casing and a tooth rail which is guided longitudinally displaceable relative to the casing. Once the cartridge is inserted, the casing is fixed on the upper part of the punch, while the tooth rail is fixed on the lower part of the punch. A transport serration is formed in the casing. The tooth rail has a retaining serration. During the opening and closing movement of the punch, the transport serration and the retaining serration interact as transport mechanism which displaces the cut off resected chips in the cartridge in the proximal direction.

Abstract: The apparatus for separating residues from a thermal waste treatment into one fine fraction and one coarse fraction comprises a housing (1) abutting on swinging elements (2), said housing having a plurality of diagonally offset plates (3.1-3.5) that are disposed one beneath the other and are connected to said housing (1) by their side edges, and being equipped with means (5) for generating a vibration component oriented in the direction of the plates (3.1-3.5) disposed diagonally offset downward. The apparatus further comprises one suction line (6) as well as an inlet opening for a gas that may be passed between the plates for wind sieving. Residues or slag from a waste treatment plant or an incineration plant are supplied to this apparatus in order to separate them into at least one fine fraction and one coarse fraction.

Abstract: The combustion system for implementing the process has a combustion grate, hoppers below the combustion grate for supplying primary combustion gas through the grate and nozzles that lead into the furnace above the combustion grate to supply secondary combustion gas. At least one extraction duct for flue gas is provided at the rear end of the furnace above the combustion grate. This duct is connected to the suction side of a fan. The pressure side is connected to nozzles arranged in the upper area of the flue gas pass. The nozzle height allows the flue gases a residence time of at least 1 second after secondary gas is supplied.
