Abstract
The invention relates to a method for measurement and simple and fixedly structured regulation of quality-determining parameters of the glass bath. According to the invention batch coverage, batch compression, the position of the thermal key points of heat sinks and sources, in particular the glass bath surface and the flames, are optically measured, compared as set values or in subsequent regulation as control parameters and adjusted by fuel actuation, fuel distribution, burner inlet pressure, implementation of additional heating or bubbling throughput. In the image section of a furnace chamber camera, which is adjusted in real proportions, a distinction is made in pixel-wise manner as batch or glass, preferably after color weighting. At the top of the regulating hierarchy a regulating circuit regulates the degree of batch coverage. The proportion of batch listed in image line-wise manner in the transverse direction of the furnace and its linearised axial configuration in the melting zone is determined as batch compression which is essential for the method and which is governed by the recirculation flow and it is used as an actual value input of a batch drift regulating circuit. In transverse flame furnaces after positional deviation of the flame-axial glass hotspots from the central position axially of the furnace, which is most intensive in terms of flow and which is fixed in respect of a set value, a firing control regulating circuit sends a flame length control parameter to its subsequent flame length regulating circuit which in the firing period currently regulates the flame key point. A disturbance-variable feed-forward system at the control regulating circuit avoids overheating of the edges of the withdrawing port. Intensive cross-flow mixing and marked reaction space separation of the melting and refining zone is the quality assurance which is typical of the method.
