Definitions
- the invention relates to a method for producing and refining a glass melt in a glass melting tank and to a corresponding glass melting tank.
- the glass melting tank is fed to a mixture which is converted or transferred under the action of heat in the glass melting tank in the glass melt.
- the heat generation is realized in the combustion chamber of the glass melting tank, for which purpose in this combustion chamber fuel is introduced.
- fuel For combustion of the fuel, air and / or oxygen is supplied into the combustion space.
- the present invention seeks to provide a method for producing and refining a molten glass in a glass melting tank or a corresponding glass melting tank, in which or at the combustion of fuel in the combustion chamber of the glass melting tank can be designed more favorably and with a higher degree of efficiency, whereby a slower combustion of the fuel compared to the prior art and thus a more constant formation of flames should be achieved.
- This object is achieved with regard to the method for producing and refining a glass melt in a glass melting tank by introducing wood dust into the combustion chamber of the glass melting tank, which is present above the glass melting tank, where it is burned off with the supply of air and / or oxygen.
- the formation of flames in the combustion chamber can be strengthened, resulting in better
- the wood dust can be blown in accordance with an advantageous embodiment of the method according to the invention in the existing above the molten glass combustion chamber of the glass melting tank. This allows the actual Combustion process, which is accompanied by air and / or oxygen supply in this combustion chamber, make favorable.
- comminuted or ground wood particles are used as wood dust. Since, in the area of a wood particle, partially sub-stoichiometric combustion conditions result, from a small-scale perspective, a reduction of the NOx content in the exhaust gas can be achieved.
- the quality of the combustion in the combustion chamber can be further increased.
- the wood dust is blown with natural gas, the above-mentioned effect can be enhanced with the partially substoichiometric combustion ratios.
- the glass melting tank according to the invention for producing and refining a glass melt from the glass melting tank supplied mixture, which has a burner device, by means of the fuel in the present above the molten glass combustion chamber of the glass melting tank can be introduced and burned there under air and / or oxygen
- the object underlying the invention is achieved in that at least one wood burner belongs to the burner device, by means of which wood dust can be introduced into the combustion chamber of the glass melting tank which is present above the molten glass.
- the at least one wood burner of the burner device is designed so that it the wood dust in can inject the combustion chamber of the glass melting tank above the molten glass.
- the glass melting tank or its wood burner can advantageously be designed so that with the wood dust air, natural gas, oxygen or any suitable gas mixture in the combustion chamber of the glass melting tank is blown above the glass melt.
- biomass can be used as fuel by the use of wood.
- the glass melt is arranged in the lower region of the glass melting tank, above which a combustion chamber is provided inside the glass melting tank.
- the glass melting tank is fed through a suitable metering device to a mixture containing the required for glass formation material components. This mixture is transferred into the molten glass within the glass melting tank or converted into molten glass.
- heat is generated within the glass melting tank, to an extent which keeps the glass melting tank within the temperature range required for the operation of the glass melting tank.
- fuel in the form of wood dust is blown into the combustion chamber of the glass melting tank above the molten glass.
- wood dust shredded or ground wood particles are used.
- the injection of the wood particles takes place by means of wood burners, which form the burner device of the glass melting tank.
- the wood dust may e.g. be blown into the combustion chamber with natural gas.
- an effect can be achieved or enhanced, according to which partially substoichiometric combustion conditions result in the region of the respective wood dust particles, whereby a reduction of the NOx content in the exhaust gas is achieved.
- the combustion of the wood dust in the combustion chamber has the consequence that a comparatively steady flame formation is achieved, which leads to favorable thermal conditions within the glass melting tank.
- the use of wood dust results in significant economic benefits compared to prior art fuels such as oil and gas.
- the burner device has burners functioning in addition to wood burners based on other fuels.
