Sorg EME-NEND charger and IRD Doghouse - a successful development

The Sorg company came up in the last decades with numerous innovations most of them
contributions to increased energy efficiency, reduction in emissions of greenhouse gases,
or special solution for waste incineration. Sorg has realized the first flue gas heat recovery
system for glass batch preheat in 1987. The very specific problems associated with the
batch preheating are well known and the reason for clear restrictions in operation
conditions in the past.
Sorg has realized in 2012 a batch preheating system which allows an operation without
most of these restrictions. Sorg has completed this heat recovery concept with a number
of special design features. Gas tight attachment of the charging device to the furnace
charging pocket and the enlarged charging pocket, the so called Sorg IRD doghouse,
are developed in order to reduce any dusting and corrosion problems associated with
the hot and dry batch charging. Since 2012 this concept was realized over 36 times
world wide. The special design features were developed using CFD modeling. The results
of the modeling investigations correspond well with the performance of the realized concept.
