Definitions
- the invention relates to a batch melting furnace (glass) comprising a submerged burner combined with an overhead burner.
- the submerged burner may in particular act as a barrier to solid batch materials.
- the air burner, especially in the vault has a flame impacting the surface of the molten bath above the flame of the submerged burner, and contributes to the melting of batch materials.
- the submerged burners for melting glass are known, in particular from WO9935099 and WO9937591.
- Arc burners are known for glass melting, in particular WO02 / 092521, US6237369, WO9931021 and WO02 / 090271.
- Other documents include SU425853, US5139558, EP1236691, JP2002284532, US5922097, US202166343.
- the vitrifiable materials are introduced upstream of the furnace.
- we want their perfect fusion that is to say, the absence of unfused in the final glass.
- the present invention contributes to solving this problem.
- At least one submerged burner is associated with at least one aerial burner, in particular placed in a vault, the flame of which impacts the surface of the molten bath (in glass) above the flame (or the bubble, taking into account the In fact, it is generally combustion gases that emerge from the molten glass and not a flame of the submerged burner, so as to produce a locally very hot zone on the surface of the glass and eliminate the unmelted particles by melting them.
- This device can be completed by a barrage of submerged burners to further increase the efficiency of the device and to melt the solids.
- surface burner the air burner whose flame impacts the glass surface above the flame of the submerged burner.
- the furnace according to the invention is equipped with at least one overhead burner, said overhead burner being associated with at least one submerged burner, the flame of said overhead burner touching the surface of the molten bath at the place where the bubble of said submerged burner.
- Such an overhead burner is called "surface burner” in the part of this application.
- a dam comprising at least one submerged burner prevents vitrifiable materials to pass downstream of said dam. The vitrifiable materials can then only cross the dam in the molten state. The dam brings more heat contributing to the melting of any vitrifiable material passing through it.
- the submerged burner raises the colder (melted and unmelted) materials, naturally at the bottom of the oven, to the surface, and returns them downstream of the oven after reheating.
- the associated surface burner helps accelerate melting, in combination with the submerged burner itself.
- the invention relates first of all to a vitrifiable material melting furnace comprising, upstream of the flow direction of the melts, a zone for introducing solid vitrifiable materials, said furnace comprising a submerged burner and a surface burner which is an overhead burner providing a flame from the surface of the glass where the immersed burner bubble emerges.
- the invention relates to the principle of the combination of a submerged burner and a surface burner, in particular placed in a vault, said submerged burner may have the function of barrier effect for vitrifiable materials.
- the flame coming from the surface burner impinges the glass above the flame (or the bubble, considering that it is generally combustion gases that emerge from the molten glass and not a flame) from the submerged burner, so as to produce a locally very hot area on the surface.
- the submerged burner raises colder materials on the surface, these materials are heated on the one hand by the flame of the submerged burner and on the other hand by that of the surface burner. This is a way to bring calories directly to the coldest materials.
- Such efficiency can not be achieved if the immersed burner is replaced by a bubbler (non-ignited gases) or recovered combustion fumes, since these gases would contribute to the pre-cooling of the materials raised, which would be counterproductive.
- the surface burner (usually vaulted), which is dimensioned so that the combustion of gases takes place at the level of the burner bubble immersed, selectively warms the cold glass rising to the surface. Thermal transfers that depend on the temperature difference between the hot source and the cold point are greatly improved.
- the invention makes it possible to reduce energy consumption.
- superstructure temperatures upper temperature limit that supports the materials constituting the oven
- the submerged burner may also be part of a submerged burner dam each producing convective motions in the melt and preventing solid batch materials from flowing downstream of the furnace.
- a submerged burner dam each producing convective motions in the melt and preventing solid batch materials from flowing downstream of the furnace.
- the oven is wide, it is preferable to constitute a barrier to vitrifiable materials by a multiplicity of submerged burners.
- These submerged burners are then preferably placed in line across the main flow direction of the melts. This main direction corresponds to the direction from upstream to downstream, along the axis of the furnace.
- the submerged burners can be shifted slightly with respect to a straight line, provided that the dam effect is obtained.
- the bubbles from the submerged burner give a convective motion to the solids and return them to the upstream of the furnace.
- the dam comprises only one submerged burner
- it is generally located in the middle of the width of the oven (midway between the side walls of the oven).
- the dam comprises several submerged burners
- said surface burners being preferably placed opposite the vertical of each submerged burner, so that the flame of a surface burner affects
- the dam then comprises immersed burner / surface burner pairs, each submerged burner being associated with a surface burner.
- the furnace according to the invention may comprise several successive dams (2 or 3 see more) on the path of melts, each dam each comprising at least one submerged burner.
- the gases from each surface burner arrive with a fairly high speed on the surface of the glass, for example with a speed of at least 15 meters per second. This speed can be much greater, and it is also regulated according to the risk of flight of materials on the surface of the bath.
- the flame of the surface burner arrives near a slope of composition, it is preferred to limit the speed of its gases so as not to cause flight of material from the slope. This speed can for example go up to 150 m / s, and in case of risk of flotation of vitrifiable materials preferably up to 40 m / s.
- the number of submerged burners to be used to constitute the dam is sufficient for the unmelted materials not to pass through it and to be returned upstream.
- N SUff of submerged burners such that N SUff is at most equal to 1 + the integer part of [120% of L / 2R], if L is the oven width and if R is the radius of the emerging bubble of a submerged burner.
- N SUff is at most equal to 1 + the entire portion of [L / 2R].
- the diameter of the emerging bubble of a submerged burner can be determined by visual observation.
- the radius R (in meters) of the bubble of a submerged burner (fed with pure oxygen as oxidizer and methane as fuel), at the moment when it reaches the surface, is at least equal to:
- - P is the power of the burner in KW
- - V is the kinematic viscosity of the glass in mVsecond.
- the power of a submerged burner can for example go from 10 to 150 kW.
- the power of a transverse air burner can for example go from 100 to 1000 kW.
- the power of a surface air burner can for example go from 300 to 3000 kW.
- all submerged burners are regularly placed at regular intervals across the glass bath so as to produce the dam effect.
- the dam comprises several submerged burners, it includes two burners immersed closer each of one of the transverse walls of the oven. These burners, placed at the ends of the dam, are separated by a distance d from their nearest wall.
- the distance between two submerged burners of the same dam is preferably 2d.
- 2d corresponds substantially to the diameter of the emerging bubble of the submerged burner.
- the furnace according to the invention may therefore have a dam comprising several submerged burners, a different surface burner being associated with each submerged burner of the dam.
- the oven according to the invention can be equipped with transverse air burners.
- the oven can also be equipped with overhead burners, crossing the side walls from the oven. Electrode pairs directly heating the molten glass, especially through the hearth, can also participate in the overall heating of the furnace.
- the invention considerably improves heat transfer to the glass bath.
- the submerged burner increases the convection in the furnace and constantly raises cold glass to the surface of the glass bath. This increase in convection is done without cooling the hearth, which would not allow a simple bubbling of cold gases or fumes.
- the volume of gas sent by a bubbler represents only 10% of the volume of gas generated by a submerged burner.
- Combustion fumes generally have a temperature of around 1500 to 1600 0 C, while a submerged burner flame has a higher temperature, especially above 1800 0 C, 2000 of around 0 C (rather the case of a combustion air / fuel gas) at 2500 0 C (rather in the case of an oxygen / fuel gas combustion).
- the flue gases cool rapidly as soon as they have to be transported.
- a submerged burner brings a lot more thermal energy directly into the glass because of the combustion that intervenes directly.
- the vitrifiable materials can be introduced above the glass bath, in which case they form a composition slope, which can float (depending on their nature) on the melts. They can also be introduced below the glass bath.
- the submerged burner (and thus also the possible dam of which it is part) is generally placed between the end of the composition slope and the exit of the furnace, for example between the end of the composition slope and the middle of the oven between its entry and exit.
- the invention therefore also relates to the method according to which the vitrifiable materials are introduced above the molten bath and form a composition slope, the immersed burner (and therefore also the possible dam of which it forms part) being placed at the end of said embankment.
- the vitrifiable materials may include raw materials, but also cullet, or even waste to be vitrified. They may also include fuel elements (organic): it is thus possible to recycle, for example, sized mineral fibers, with binder (of the type used in thermal or acoustic insulation or those used in plastic reinforcement). , laminated glazing with polyvinyl butyral type polymer sheets such as windshields, or any type of "composite" material combining glass and plastic materials such as some bottles.
- This or these points of introduction into the glass bath may (can) thus be near the surface or more deeply into the glass melt, for example at a bath height of glass between 1/5 th and 4/5 th of the total depth of the glass bath from the level of the sole.
- Each burner (submerged or aerial, transverse or surface) is powered by an oxidant and a fuel.
- the oxidant may in particular be air or oxygen or air enriched with oxygen.
- the fuel may be of the gaseous or non-gaseous fossil fuel type such as natural gas, propane, liquid fuel oil or any other hydrocarbon fuel. It can also be hydrogen, especially for submerged burners. Combining in a submerged burner melting the use of an oxygen oxidizer and that of a hydrogen fuel is a good way to ensure an efficient heat transfer of the energy of the burners to the molten glass, leading otherwise to a process completely "clean", that is to say without emission of nitrogen oxide NOx, nor of greenhouse gases of COx type other than that which can come from the decarbonization of the raw materials.
- a surface burner is associated with a submerged burner, the flame of the surface burner touching with a high speed the place where the combustion gases of the submerged burner emerge.
- the submerged burner it is possible for the submerged burner to be over-stoichiometric in oxygen (that is to say, enriched in oxygen with respect to what would be sufficient to burn all the fuel supplying the submerged burner) and that the surface burner associated therewith or over-stoichiometric fuel gas (that is to say fuel-enriched with respect to what would be sufficient to react with all the oxidant supplying the surface burner).
- This type of submerged burner melting considerably reduces the emission of any type of dust in the melting chamber, and NOx-type gas because the heat exchange is done very quickly, avoiding temperature peaks likely to promote the formation of these gases. It also considerably reduces the emission of CO 2 gases, the total energy consumption of the installation being lower than with conventional devices (only by reversing air burners, for example).
- preheating stage vitrifiable materials at a temperature however significantly lower than that required to liquefy, for example at most 900 0 C.
- thermal energy of the fumes By exhausting them thus thermally, one can globally reduce the specific energy consumption of the installation.
- the glass is generally refined, either downstream of the same furnace, and / or in a refining compartment downstream of the furnace. After refining, the glass can exit via a groove, but the invention also applies to ovens without grooves. In particular, after refining, the glass can continuously feed a flat glass forming installation such as a float glass bath.
- FIG. 1 shows a furnace 1 according to the invention seen from the side.
- This furnace is supplied with vitrifiable materials 2 forming a composition slope upstream of the oven, by means of a charging device 3 (worm) opening just above level 4 of the glass bath.
- a submerged burner 10 generates a flame 5 in the form of bubbles that rise to the surface. This rise towards the surface produces convection movements represented by arrows.
- the unmelted materials from the talus of composition 2 (the end of the composition slope is at 12) and approaching the place where the flame of the submerged burner emerges are pushed upstream by these convection movements.
- An overhead burner 5 produces a flame 6 impinging on the molten glass surface.
- the heating of the furnace is completed by pairs of electrodes 7 and transverse air burners 11 placed in the side walls of the furnace.
- the molten glass flows downstream of the furnace, passes through a groove 8 and flows in 9 through an orifice.
- FIG 2 shows schematically the preferred location of placement of the submerged burner 21 (and therefore also the possible dam which it is part).
- this burner 21 emerges on the surface a bubble 22 charged with combustion gas.
- the burner is preferably placed at the end of the slope of composition 23 so that it contributes to trimming the said slope.
- the dotted line represents the shape of the composition slope in the absence of a submerged burner and in the absence of a surface burner. The end of this slope will end at point 24.
- the submerged burner dam crushes the end of this slope, so that this end is now at point 25.
- the surface burner 26 is placed vertically to the submerged burner and its flame 27 comes to touch the surface of the glass at the emergence point of the bubble 22 of the submerged burner 21.
- the surface burner also contributes to shortening the end of the slope.
- the submerged burner is placed under the end of the slope of composition that would be formed in its absence (dashed line), so that finally, when operating, said submerged burner is just downstream (relative in the flow direction of the glass) of the composition slope.
