Abstract: A raw material mixture is supplied to an extrusion machine by a moved supply unit in a particularly uniform manner. The raw material mixture has a fiber raw material and a carrier raw material. The fiber raw material has a process by-product of a food manufacturing process and the carrier raw material has whole-grain components. A raw material quantity is supplied by the supply unit along a trajectory through the supply opening into the production machine. The trajectory of the raw material quantity is changeable. The supply unit has at least one actuating unit, by which an actuating movement of the supply channel portion and/or of the feed hopper can be generated, so that the supply channel portion can be caused to displace relative to the feed hopper.

Abstract: A raw material quantity is supplied by a supply unit along a trajectory through a supply opening into the production machine. The trajectory of the raw material quantity is changeable. A supply unit for supplying a raw material quantity into a production machine comprises a supply channel portion having an exit opening and a feed hopper. The supply unit has at least one actuating unit, by which an actuating movement of the supply channel portion and/or of the feed hopper can be generated, so that the supply channel portion can be displaced relative to the feed hopper. A raw material mixture is supplied to the extrusion machine by the moved supply unit. In this way it is possible to supply the raw material mixture into the extrusion machine in a particularly uniform manner so that the raw material mixture can be processed by means of the extrusion machine.

Abstract: In a device for the purification of exhaust gases, especially exhaust gases consisting of fluorine-containing compounds, bore holes (7,8) are made in a ring burner (5) for the separate supply of combustion gas and oxygen on a single hole circle around a central exhaust gas supply (9). The ring burner is arranged in a combustion chamber (1). The combustion chamber is closed up to an annular gap (20) between a cylindrical jacket (4) and a front face (16). Additional oxygen or additional air is introduced into the annular gap (20).

Abstract: Exhaust gases from CVD and plasma processes contain toxic pollutants, particularly fluorine-containing compounds, and must therefore be purified. In a device for the purification of exhaust gases, frequently one comprising a combustion chamber and a fuel gas flame, the pollutants are converted by means of a thermally activated, chemical reaction. A special design of the combustion chamber and the burner improves the economy of the exhaust gas purification process and, above all, reduces the amount of nitrogen oxide contained in the purified exhaust gas. To this end, it is ensured that a flame having a reducing effect over its entire cross section forms in the burner by separately supplying fuel gas and oxygen in an alternate manner into drill holes arranged on a single hole circle and by sealing the combustion chamber such that no additional air is supplied to the vicinity of the burner.

Abstract: The invention relates to a modular system for the treatment of process exhaust gases containing pollutants. The object is to propose a possible way of carrying out the aftertreatment of process exhaust gases of this type which allows reliable operation at low cost. The intention is to allow sufficient redundancy and also flexible adaptation to increasing capacities to undergo aftertreatment. The modular system according to the invention is in this case designed in such a way that there is an electronic control for burners, the supply of process exhaust gases, washing liquid and/or of fuel gases in reaction chambers. At least two reaction chambers form modules which can be controlled by means of the electronic control for simultaneous or alternating treatment of process exhaust gases, taking account of detected operating states at the system or at least one module.
