Melting Furnace Having Infinite Furnace Campaign

Abstract

The invention relates to methods and to devices for a melting furnace, or for the conveying lines of the product to be melted, having an infinite life (furnace campaign). The same is achieved by means of the continuous/periodic, e.g. cyclic, exchange, in the optimum case, of all of the components surrounding the furnace interior/melting space, or surrounding the conveying lines, in that the components can be arranged/placed next to each other in a modular manner and that said components move in a certain direction while new individual parts are added at one of the free ends of the respective assembly and while worn/used individual parts are removed at the other free end of the respective assembly. For this purpose the individual components are held and/or moved by suitable receptacles, wherein the furnace interior/melting chamber remains stationary.

Description

The invention relates to methods and apparatus of a melting furnace with infinite furnace campaign. This is implemented by a continuous/periodical thus cyclic exchange of, in the best case, all components of the melting furnace that surround the interior of the furnace/melting space, wherein the components are modularly placed or arranged next to each other, move in a predetermined direction, have a specific shape and are supported by suitable receptacles and moved and/or turned wherein the furnace interior/melting space remains stationary.

A melting furnace of this type is known from document DE 43 27 237 C1.

Known apparatuses in the area of glass melting technology are furnaces which are assembled from selected fireproof materials. In the simplest case they are composed essentially of a base plate or base plate, sidewalls, a vault and an end walls which together surround the inner space of the furnace or furnace interior/melting space. In order to keep the individual components in their predetermined position and in order to absorb the in some areas considerable forces, comprehensive steel constructions are necessary, which are summarised under the term bracing or anchorage. The entire glass melting furnace is subject to wear (corrosion/erosion) and has therefore a limited lifetime (furnace campaign). In particular in the area of the introduction/feeding of the glass raw material (feeder forpart) and of the glass exit (flux line) the glass contact stones underlie a strong wear.

This type of furnace design for melting of glass is with respect to today's modern mechanical components, data analysis systems and control possibilities, short-lived, cost intensive and inefficient.

OBJECT

An exchange of worn out components of the melting furnace is, mainly due to the high temperature, only possible by shutting down and cooling down of the entire glass melting furnace whereby the fabrication of glass is stopped for a long period in time.

Repair of worn out components without shutting down and cooling down is only possible under limitations and prolongs the furnace campaign of the glass melting furnace only marginally.

After a few years the entire melting furnace has to be completely renewed.

It is therefore an object of the disclosure to provide methods and apparatuses that enable an infinite furnace campaign of melting furnaces, by implementing a continuous/periodical, thus cyclic exchange of the worn components of the melting furnace of all components of the melting furnace, wherein the components are modularly aligned/arranged next to each other, move in a certain direction, thereby providing a specific shape and supported by adapted receiving elements and moved and/or turned, wherein the furnace interior/melting space remains stationary.

This object is resolved by the features of the method claims 1 to 39 and apparatus claims 40 to 66.

The respective examples are specified in the dependent claims.

Advantages achieved by the present disclosures are essentially that the melting furnace produces glass without interruption or without essential interruption and can be continuously adapted to new method and materials.

It is, of course, although possible that the raw material feeding and/or the removal of the melt (13) occurs via the base plate/bottom (1) in a manner, that suitable openings are provided in selected individual elements of the base plate (1a), in this case an infinite furnace campaign without interruptions of the flow of melting material is possible.

The addition of raw materials, energy, the removal of melt (13), exhaust gases and the intake of measurement probes or others can, if it makes technical sense, be inserted through suitable openings in all component subassemblies (1, 4, 7, 10, 14, 17, 20, 23) or in the respective individual elements (1a, 4a, 7a, 10.1a to 10.na, 10.1b to 10.nb, 10.1c to 10.nc, 14a, 17a, 20a, 23a) of the respective component subassemblies (1, 4, 7, 10, 14, 17, 20, 23), or can be integrated in individual elements (1a, 4a, 7a, 10.1a to 10.na, 10.1b to 10.nb, 10.1c to 10.nc, 14a, 17a, 20a, 23a) of the respective component subassemblies (1, 4, 7, 10, 14, 17, 20, 23), this also applies for bridge walls or individual elements of bridge walls; with suitable arrangement of quarls/nozzle bricks of individual nozzle brick/quarl elements (10.1b to 10.nb), it is possible to exhaust the exhaust gases through these openings, after removing of the burners.

By lifting or lowering of individual elements of the bottom (1a), as shown in FIG. 9 out of the plane of the entire surface of the bottom (1), a modification of the current in the melt (13) or barriers in the melt (13) for the promotion of current fields in the melt (13) or aid for the withdraw or local binding of impurities in the melt (13) can be achieved, as well as the lifting of single pieces of the bottom (1a) for modifying the gaseous current fields in the upper part of the furnace, as well as for the follow up of the individual elements of the bottom (1a) in an existing wear of the individual elements of the bottom (1a) or for a cross movement of the individual element of the bottom (1a) with corresponding implementation of the individual element of the bottom (1a) from the plane of the entire surface of the ground plate (1), wherein these cross wise movements as well as the follow up with existing wear is of course also possible for all other individual elements (4a, 7a, 10.1a to 10.na, 10.1b to 10.nb, 10.1c to 10.nc, 14a, 17a, 20a, 23a) of the respective component subassemblies (4, 7, 10, 14, 17, 20, 23) for all different modifications of the melting bath (13) or modifications of the gaseous phases or similar which are known to a person skilled in the art.

For easy arrangement/alignment of the individual elements of the end wall (4a, 7a), of the individual elements of a bridge wall between single separated chambers with respect to each other, individual elements of the end wall (4a, 7a) or individual elements of the bridge wall can, in place of the shape of a straight cylinder segment, be in form of a straight hollow cylinder segment in both cases, for the cylinder segment as well as for the hollow cylinder segment the expression cylinder segment is used.

The arc segments of the entire sidewall with vault (10.1 to 10.n) can also comprise more different individual elements (10.1a, 10.1b, 10.1c) than the given three individual elements (10.1a, 10.1b, 10.1c), the individual sidewall element (10,1a), the individual nozzle brick or throat element (10.1b) and the individual vault element (10.1c) which can also move with respect to each other or in opposing directions with respect to each other and/or with different velocities; the vault (10.1c to 10.nc) can be termed ceiling in a planar embodiment; the arc segments of the entire sidewall with vault (10.1 to 10.n) as well as the other component subassemblies (1, 4, 7, 10, 14, 17, 20, 23) can fulfil further requirements beside their intended use, for example, the arc segments of the entire sidewall with vault (10.1 to 10.n) over the cover of the melting furnace can be a cover for other processes of the melt (13), for example a cover of haulage tracks of the melt (13) or a cover of an exhaust channel, up to the delivery of the exhaust gases to the atmosphere and with a corresponding implementation also of the recuperative process, the heat exchange of the combustion air.

In case of continuation of the sidewalls with vault (10.1 to 10.n) as limitation for the exhaust gases with respect to the atmosphere, it is also possible to use a planar base plate (1) of the exhaust channel, the so-called fox as well as one or more adjacently arranged vaulted bottoms (1), in cylindrical form, as partially hollow cylinder with eventually different radii (R3, R4).

The entire melting furnace can also comprise a plurality of chambers arranged one after the other, the separation of which comprises an additional separation wall, bridge wall or end wall (4, 7) in between the chambers and may be connected by haulage tracks and which allow material and energy currents by suitable openings in order to separate manufacturing phases; these separation/bridge walls or end walls (4, 7) can comprise several separation walls (4, 7) or end walls arranged directly one after the other which are moveable in translation or rotation with respect to each other in order to time wise close, open or delimit openings or apertures.

In the same way the translational or rotational velocity of the respective component subassemblies (1, 4, 7, 10, 14, 17, 20, 23) can be adapted with a modification or change of individual elements (4a, 7a, 10.1a to 10.na, 10.1b to 10.nb, 10.1c to 10.nc, 14a, 17a, 20a, 23a) for serious test series, with a defect or similar, such that these individual elements (1a, 4a, 7a, 10.1a to 10.na, 10.1b to 10.nb, 10.1c to 10.nc, 14a, 17a, 20a, 23a) of the melting furnace or the haulage track can be removed as fast as possible in order to prevent damages, problems or impurities in the melt (13) or in the entire melt and manufacturing system.

A rotation or turn of rotational component subassemblies (4, 7, 10, 14, 17, 20, 23) during the furnace campaign during a complete turn is also possible, as well as a fast rotational movement of rotational component subassemblies (4, 7, 10, 14, 17, 20, 23) in comparison to other moveable component subassemblies (1, 4, 7, 10, 14, 17, 20, 23) or a fast translational displacement of translational component subassemblies (1, 10, 17) in comparison to other moveable component subassemblies (1, 4, 7, 10, 14, 17, 20, 23) is possible. The movement/displacement of individual component subassemblies (1, 4, 7, 10, 14, 15, 17, 20, 23) can be achieved by a force applied on the resulting alignment/arrangement/contact surface of the individual elements which was the last to be added (1a, 4a, 7a, 10.1a to 10.na, 10.1b to 10.nb, 10.1c to 10.nc, 14a, 17a, 20a, 23a) or on the alignment/arrangement/contact surface of the individual element that was the last to be added (1a, 4a, 7a, 10.1a to 10.na, 10.1b to 10.nb, 10.1c to 10.nc, 14a, 17a, 20a, 23a) of the respective component subassembly (1, 4, 7, 10, 14, 15, 17, 20, 23) or in the case of a component subassembly (1, 4, 7, 10, 14, 15, 17, 20, 23) consisting of one exchangeable element at the alignment or arrangement surface of which the subsequent exchangeable element in the direction of the respective direction of movement (A, B, C, D, E, F, G) of the respective component subassemblies (1, 4, 7, 10, 14, 15, 17, 20, 23).

In order to delimit forces and moments on the single elements (1a, 4a, 7a, 10.1a to 10.na, 10.1b to 10.nb, 10.1c to 10.nc, 14a, 17a, 20a, 23a) on certain individual elements (1a, 4a, 7a, 10.1a to 10.na, 10.1b to 10.nb, 10.1c to 10.nc, 14a, 17a, 20a, 23a) or on entire component subassemblies (1, 4, 7, 10, 14, 15, 17, 20, 23), the individual elements (1a, 4a, 7a, 10.1a to 10.na, 10.1b to 10.nb, 10.1c to 10.nc, 14a, 17a, 20a, 23a) parts of the individual elements (1a, 4a, 7a, 10.1a to 10.na, 10.1b to 10.nb, 10.1c to 10.nc, 14a, 17a, 20a, 23a) or the entire component subassemblies (1, 4, 7, 10, 14, 15, 17, 20, 23) can be turned, twisted or moved force and back.

The heating up of the newly attached or added individual elements (2, 5, 8, 11, 15, 18, 21, 24) at the respective component subassemblies (1, 4, 7, 10, 14, 17, 20, 23) can happen mainly or exclusively by heat exchange with the respective component subassemblies (1, 4, 7, 10, 14, 17, 20, 23) at which the newly added or attached individual elements (2, 5, 8, 11, 15, 18, 21, 24) are added or attached, as well as the cooling down of worn or used single elements (3, 6, 9, 12, 16, 19, 22, 25) can occur in the same way.
