Abstract: The invention relates to a method and device for influencing the smell coming from shaft openings of underground sewers, in which water droplets are sprayed into the air in shafts (1) of underground sewers which are open in the direction of the ambient air. Said spraying device comprises a pressure vessel (3) containing water and a nozzle (4) having one or more fine openings through which water can escape from the pressure vessel (3), the pressure vessel (3) being subject to a hydrostatic pressure which is by at least 2 bars greater than the ambient pressure, and the diameter of one or more nozzle openings being less than 130 ?m.

Abstract: A method and to a device for delivering deliverable materials through a hollow chamber that is closed off from the outside air in a pressure-tight manner and that is supplied with materials via a storage container serving as a lock and that ends in the furnace chamber via a connecting tube. The delivery of the materials within the hollow chamber closed off from the outside air in a pressure-tight manner is carried out by means of depressurized mechanical conveyors.

Abstract: The invention relates to a drum mixer wherein a drum containing a mixable product and rotatably mounted on a frame and a drive for rotating the drum about the axis of rotation thereof, wherein the mixer is provided with an extraction line which receives the mixable product from the drum by the extracting opening thereof through the front filling opening of the drum. The aim of the invention is to provide an advantageous structural design. For this purpose, the invention provides for a support connected to the frame to which the extraction line, which is projected in the mixable product of the drum is fixed, preferably rigidly, in such a way that forces are removed at least partially.

Abstract: A device and method for charging processing plants, in particular, combustion furnaces (1), is disclosed, in which a flowing process material (3), which has solid components (6) in addition to liquid components (5), is introduced into the processing plant (1), by means of a conveyor line (2) under pressure. According to the invention, advantageous charging conditions may be achieved, by means of mixing the process material (3) before pressurization.
