The goal of the latest strategy in glass companies is to decrease the cost of production while maintaining or increasing the glass quality. There are several perspective ways leading to this goal: Optimization of the heating system, Modification of the furnace design, or Installing the new advanced control system. Optimization of the heating system can be achieved by installing modern burner sy...

ABSTRACT:A mathematical model for the performance prediction of an industrial glass furnace with six ports on each side was developed. This model comprises of two main sub-models for the combustion chamber and glass-melting tank.

This paper presents a practical application of fuzzy logic to the temperature control of glass melting furnace for television picture tube. Because of the complexity and nonlinearity, temperature control of glass melting furnace is still delegated to human operators. Though the overall characteristics of glass melting furnace are complex and nonlinear, one part of the furnace characteristics ca...

Absrract This paper presents a practical application of the conventional multi-loop control method for the temperature control of a television glass furnace. To control the temperature of the TV glass furnace, major input-output variables are selected, and simple FirstOrder-Plus-Dead-Time(F0PDT)models are established with the process experimental data. Based on the FOPDT models, a multi-loop. c...

The Research Group for Automation of the Central Research and Design Institute for Silicate Industry (CRDISI) has been working for some years on the automation of technological processes in the silicate industry, in cooperation with the Department of Automation of the Technical University of Budapest (DATU). CRDISI yields the technological background, provides for the hardware tools and the bas...

An explicit equation leading to a method for improving furnace efficiency is presented. This equation is dimensionless and can be applied to furnaces of any size and fuel type for the purposes of comparison. The implications for current furnace design are discussed. Currently the technique most commonly used to reduce energy consumption in galvanizing furnaces is to increase burner turndown. Th...

The manufacture of optical fibers typically involves taking a solid glass cylinder (a blank or preform), heating it up to melting temperature by feeding it through a cylindrical furnace (the drawing tower), and drawing the molten blank from the other end of the furnace at high speed (tens of meters per second). Since the drawing speed is much faster than the feeding speed (by a factor of at lea...
