  • Effect of Soda Ash's Particle Size Distribution on Glass Melting
    Glass & Enamel, 2020
    Co-Authors: Lin Jian
    Abstract:

    Soda ash is one of important materials in flat Glass production. The particle size has great influence on Glass Melting. A lot of experiments for Melting and refining were used to study influence of soda ash's particle size distribution on batch's Melting and refining process. Optimized results were obtained. Too coarse particles are harmful to Glass Melting. The upper limit should be less than 26 meshes. Finer powder's content should be controlled within a proper range.

  • Technologies and services for oxy-fuel Glass Melting
    International glass journal, 2020
    Co-Authors: P. Zucchelli
    Abstract:

    Even if the first industrial experiences already occurred several decades ago, the penetration of this technology has really start to grow in the early 90's in parallel with more stringent environmental regulations in the US. Today, based on the total oxygen sales to the Glass industry, the global penetration of this technology is estimated at 13% of the world gloss production. The main driving forces for oxy fuel conversions are; fuel savings and capitol costs reduction; increase of furnace flexibility and productivity; reduction of environmental emissions; foot print and quality optimisation. AIR LIQUIDE'S first experiences with oxy fuel Glass Melting started also more than 20 years ago. Significant development efforts made during the 90's have led Air Liquide to hold a major oxy fuel market share. As a msult, a strong consolidated knowledge has been acquired and a large portfolio of dedicated technologies and services is now available in order to help Glass makers implementing oxy fuel firing: (1) The ALGlass burner range covering several families of oxy fuel burners; Standard pipe in pipe burners producing cylindrical flames; Variable momentum burners; Separated jets burners producing very Low NOx flat flames. (2)Dedicated modelling software tools to simulate the oxy fuel gloss Melting behaviour: AIRLOG for heat & mass balance calculations (OD); ATHENA for the explicit 3D modelling of flows and temperatures in the Glass Melting furnace (combustion chamber and molten Glass bath). Basic engineering, process control and audit services before and after oxy fuel implementation.

  • Oxy Glass Melting : Recent developments of a competitive technology
    International glass journal, 1999
    Co-Authors: P. Bodelin, Jean-francois Simon, J. M. Samaniego, L. Philippe, P. Zucchelli
    Abstract:

    The purpose of this article is to review the present and future evolutions of oxy-fuel Glass Melting. After a short historical introduction, the penetration of the oxy-combustion technology into the Glass market is illustrated from several viewpoints. Some of the motivations (energy saving and low emissions) are further discussed starting from the analysis of several industrial experiences. Finally, recent developments of the AIR LIQUIDE oxy-fuel technology are detailed.

  • WNAA - Numerical Algorithm for Studying Heat-Transfer in a Glass Melting Furnace
    Lecture Notes in Computer Science, 1997
    Co-Authors: Ivanka Zheleva, V. Kambourova, P. Dimitrov, R. Rusev
    Abstract:

    A numerical method for integration of the equation that describes heat-transfer processes in a Glass Melting furnace is proposed for different boundary conditions in a non-rectangular geometrical area. Irregular mesh is used which allows to obtain more precise results in the regions of large temperature gradients. The proposed algorithm is tested for different boundary conditions and for different embedded meshes. The results show that the algorithm is a reliable and efficient tool for investigating heat-transfer processes in a Glass Melting furnace.

  • WNAA - Identification of the Heat-Transfer in a Glass Melting Furnace
    Lecture Notes in Computer Science, 1997
    Co-Authors: Ivanka Zheleva, V. Kambourova, P. Dimitrov, R. Rusev
    Abstract:

    A simplified mathematical model of heat-transfer processes in a Glass Melting furnace is studied. The model is built up on the basis of the laws of mass conservation, the energy and the moment of a continuous 2-D medium. It is assumed that the liquid Glass melt is a Newtonian fluid. The boundary conditions describe the heat exchange on the front and back walls and the bottom of the furnace as well as the heat flow on the Glass Melting surface. The obtained system of partial differential equations is very complicated and nonlinear and no analytic solutions are known. For simplification very slow processes are only considered assuming also that the thermal problem is stationary. For solving the simplified system a numerical method is proposed. The latter allows to investigate numerically the influence of the heat flow and the insulation on the temperature distribution within the furnace. The obtained results can be used for minimizing the heat consumption of the furnace.
