OMC – Optical Melting Control

The future of melting process control

Optical Melting Control Version 2.7

While STG’s DeNOx Technology decreases NOx emissions, lowers energy consumption and lowers furnace crown temperature, there is an additional technology available for stable melting and quality conditions in the glass tank furnace. This technology is Optical Melting Control (OMC).

Based on the digital analysis of a standard furnace TV camera signal, STG’s OMC system provides for example the evaluation of

		Batch coverage This is the transformed view of the furnace with the detected batch piles, black stands for the smaller and dark red for the bigger ones.

		and
		Gradient of melting speed the linear abstraction of the Batch (black) in % of the furnace width.

		In addition, OMC also provides additional data like the length and temperature maximum position of flames, plus size and stability of bubbling spots.

This data combined with energy inputs and temperatures is available through a PCS7 control system via profibus – using the OMC video server as an intelligent transmitter.
OMC technology gives an indication of real energy transfer to glass and batch, including foam formation on the glass furnace surface, and opens a new window for advanced melting process control.
