| 20080213714 | Rotary Furnace Burner - In order to create a rotary kiln burner particularly for fine-grained solid fuels such as coal dust, with jet air nozzles which can be adjusted easily and effectively during operation of the kiln in order to change the divergence angle of the high-speed jet air streams to change the flame shape and optimise the combustion, the invention proposes attaching the jet air nozzles ( | 09-04-2008 |
| 20080289430 | Method and Device for Monitoring the State of the Protective Covering of a Rotary Furnace Burner - In order to create a process and device for the reliable monitoring of the current condition of the protective jacket, consisting of fireproof material, in particular of a rotary tubular kiln burner lance, during operation of the kiln system, the invention proposes embedding a compressed air ring main ( | 11-27-2008 |
| 20100019063 | ROTARY FURNACE BURNER - In order to provide a rotary-furnace burner in which the quantity fraction of cost-effective particulate secondary fuels to be used as energy carriers can be increased and the configuration of the burner flame can be influenced, even during the operation of the burner, it is proposed, according to the invention, to arrange an expansion chamber open towards the burner mouth and having a widened cross section, as compared with the tube or individual tubes in the burner in front of the issue of the tube or tubes for blowing out the secondary fuels, and to make the axial length and the volume of the expansion chamber variable, during the operation of the burner, by means of the axial displacement of the secondary-fuel tubes, so that the particulate secondary fuel particles blown out at the burner mouth with a considerably reduced velocity do not fly past the burner flame, but, instead, burn out in the flame. | 01-28-2010 |
| 20100050912 | METHOD FOR CONTROLLING THE OPERATION OF A ROTARY FURNACE BURNER - In order, for operating the lance burner of a rotary tubular furnace for the production of cement clinker from calcined raw cement meal, to provide an automated regulation method which is optimized in terms of the configuration of the burner flame for all types and quantities of fuels used, according to the invention a regulation method is proposed in which the characteristics of the burner flame are used as measurement variables, and the measurement variables are delivered to a controller which can vary at least three different manipulated variables of the burner, such as the spatial outflow angle and the swirl momentum of the swirled primary-airstream and/or the angle of divergence of the primary-air/jet-air jets emerging from individual nozzles and/or the velocity of emergence and/or swirl component of a stream of fragmentary alternative fuels or secondary fuels which is blown through the burner. | 03-04-2010 |

| 20100200359 | CHARGING TELESCOPE FOR CHARGING COKE OVENS - The invention relates to a charging telescope for charging coke ovens, having a vertically oriented inlet funnel and a telescope lower part which is suspended with hanging elements on a vertically adjustable lifting device. A tubular intermediate part is arranged between the inlet funnel and the telescope lower part, which intermediate part is suspended in a movable manner on hanging elements and surrounds the outlet cross section of the inlet funnel with enough free space to allow lateral compensating movements. The intermediate part has an annular flange which is sealed on an annular face of the inlet funnel. The telescope lower part also encloses the jacket of the tubular intermediate part. | 08-12-2010 |
| 20100206710 | CLEANING DEVICE FOR THE FRAME OF A COKE OVEN RETORT - The invention relates to a cleaning device for the frame of a coke oven retort with a tool carrier which can be positioned between anchor stands ( | 08-19-2010 |
| 20100314234 | METHOD AND DEVICE FOR THE POSITIONING OF OPERATING UNITS OF A COAL FILLING CART AT THE FILLING OPENINGS OF A COKE OVEN - The invention relates to a method of positioning service equipment of a coal-charging larry cart at charging ports of a coke oven, wherein a rail-guided larry cart is moved on the roof of a coke oven and is positioned at locations known by a machine control system and corresponding to charging ports in the oven roof in order to charge the oven chambers, and wherein then at least one piece of service equipment of the coal-charging larry cart is guided to the charging ports by horizontal biaxial positioning movements. According to the invention, an optical measurement method is used after each positioning of the larry cart to detect the coordinates of at least one marking that is applied to the oven roof and that has a fixed relationship with the center axis of a charging port within a measurement field that is predefined by the measurement method and to compare them with reference values that are stored in the machine control system for the marking. The deviations between the measured coordinates and the coordinates stored in the machine control system are determined for both axial directions. Differential values are then taken into account as correction values during the positioning movement of the piece of service equipment. The subject matter of the invention is furthermore formed by an apparatus for carrying out the described method. | 12-16-2010 |
| 20110030157 | APPARATUS ON A COAL-CHARGING LARRY CART FOR LIFTING A LID OUT OF A CHARGING HOLE IN THE ROOF OF A COKE OVEN AND FOR CLEANING THE CHARGING-HOLD JAMB - The invention relates to an apparatus on a coal-charging larry cart for lifting lids out of charging holes in the roof of a coke oven and for cleaning the charging-hole jambs. The basic construction of this apparatus includes a lid lifter ( | 02-10-2011 |
