Overview of Automatic Control of Glass Furnaces
نویسنده
چکیده
Glass manufacturing clearly represents a challenge for an automation engineer as it is a very complex process with complicated, nonlinear and sometimes not completely understood dynamical behavior. So it is still common that furnaces are controlled by simple controllers such as PID regulators or by manual interventions of furnace operators. As a result, the process may be kept in suboptimal conditions and acting disturbances may not be effectively rejected. However, market competition creates a need for tighter control of the process towards optimum, i.e. to maximize performance while minimizing the cost, energy consumption and emissions at the same time. Thus, advanced control strategies should be applied.

Mathematical Modelling and Identification of the Flow Dynamics in Molten Glass Furnaces
In the paper a new method for computer aided modelling and identification of flow dynamics in molten glass is presented and numerically analysed. The process of the construction of the model occurs in several steps on which the sub-models with differentiated mathematical descriptions (with distributed or lumped differential equations) and dynamical features (with inertial and oscillatory charac...

متن کاملHigh temperature in-situ IR laser absorption CO-sensor for combustion control
In view of improved control of the combustion process in e.g. industrial glass furnaces, accurate in-situ COgas sensors are required. With help of reliable in-situ gas sensors, burner control can be optimised. By better burner control, NOx emissions can be reduced and the radiative heat transfer from combustion chamber to the glass melt and thus the energy efficiency of glass furnaces can be im...
متن کاملEnergy consumption and capacity utilization of galvanizing furnaces
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...
