| 373027000 | GLASS FURNACE DEVICE | 14 |
| 20110019712 | METHOD FOR OPTIMIZING A FURNACE CAMPAIGN - The invention relates to a method and a device for extending the furnace campaign by avoiding cracks in the stones and the chipping of parts of the stones, and reducing joints in melting furnaces. Said aim is achieved by a measurement of the forces/pressures/moments of the furnace stones occurring against each other, or of the furnace stones against the bracing and defined necessary counter forces, such that the forces between the stones, or between the bracings and the stones are below the maximum permissible compression (pressure force) of the stones, and the forces required for avoiding joints between the stones are ensured. Said process occurs automatically as a form of control by determining the force of sensors, analysis of processors and data, and activation of actuators for generating counter forces. | 01-27-2011 |

| 20150063399 | VESSEL LID FOR A THERMAL PLANT - The invention relates to a vessel lid in particular for a thermal plant, for example a smelting furnace or a waste incineration plant. In particular, the invention relates to a vessel lid for a thermal plant which is arranged within vessel wall elements of a vessel wall of the thermal plant and which is either vertically adjustable and/or tiltable as a whole or which consists of a plurality of lid parts of which at least one is vertically adjustable and/or tiltable. The vertical adjustment and/or the tilting of the lid or of the lid parts and also the lateral movement thereof make it possible to achieve improved thermal sealing of the lid with respect to the vessel. The invention provides that the vessel lid or one or more lid parts/lid elements can be removed and/or exchanged. Instead of the complete exchange of the lid or of a lid part/lid element, it is also possible for only a wear layer or a screen thereof to be replaced. | 03-05-2015 |

| 20130114638 | GLASS MELTING TANK HAVING A DOGHOUSE, AND METHOD FOR HEATING THE CHARGE MATERIAL IN SUCH GLASS MELTING TANKS - A glass melting tank comprising at least one front part for introducing the charge material, and at least one charging device. To reduce atmospheric heat losses and reduce dust transport into the upper furnace of the tank, and nevertheless to intensify the heating of the charge material, the front part has a length “LV” of at least 2,250 mm in the direction of the melting tank, and a length “LG” of at least 1,200 mm is provided with an insulating roof. An end wall near the charging device, together with the roof, encloses a gas chamber open toward the melting tank. A characteristic value “K” of 3.50 tonnes (t) per hour and per square meter of surface is not exceeded. The characteristic value is calculated from P/F, where P is the throughput per hour in tonnes (t) and F is the inner surface of the front part in m. | 05-09-2013 |
