SORG: An introduction to the integrated concept

2010-09-01 | Furnace technology

An R&D project started up to develop a viable batch preheating system has provided SORG with a new, three-part concept to alleviate batch handling problems at the furnace. Used together, the different components can offer the best available solutions with regards to energy consumption, NOx emission and melting rate.

SORG: An introduction to the integrated concept
A survey amongst glass manufacturers across the world to determine the most important problem each has to face would no doubt reap a wide range of replies. The subjects fuel cost/energy consumption and emission levels, particularly of NOx would certainly be well represented on the list, and in fact, in Western Europe and possibly other parts of the world, these subjects would probably top the list.
Despite the progress that has been made in the recent past – specific energy consumption has been reduced by 40 per cent and NOx emissions by 60 per cent in the last 25 years – there is no doubt that
further improvements will be needed. It is difficult to overestimate the difficulties involved in achieving further reductions in these areas, but the new SORG Integrated Concept for batch handling at the furnace, which is the combined application of three individual components, offers the potential for progress.

THE INTEGRATED CONCEPT
The Integrated Concept is the logical follow-up to a successful SORG R&D project to develop a viable batch preheating system. A batch preheater installed between the regenerators and the stack and before a filter, if one is being used, offers the opportunity to reclaim more waste gas energy and return it directly to the process. Batch preheating can, however, cause additional problems at the furnace. The preheated batch is necessarily dry, and this can lead to severe dusting outside and inside the furnace. For this reason the new SORG batch preheater is...
