Waste Gas Cleaning   Waste Heat Recovery   Components               Waste Heat Recovery   Batch and Cullet Preheating INTERPROJEKT’s preheating system was first developed at Nienburger Glas, Germany. The hot flue gas from the glass furnace is directed through the preheater in counter flow to the glass raw materials. The flue gas and the batch and cullet are in direct contact. The results are the evaporation of the containing moisture and the removal of some of the acidic impurities, such as SOx, HCl and HF. The main features of this system are:   up to 20% energy savings   environmental benefits thanks to reductions in CO2 and NOX emissions     and the removal of SOX, HCl and HF   operating experience since 1987 (the second furnace campaign     is currently in progress)   reference installations for both cross-fired and end-fired tanks as well     as for oxy-fuel furnaces Secondary Heat Recovery Installation of boiler / heat exchanger for the generation of:   steam for power generation and heating processes, interesting for big     installations like float furnaces   hot water for plant use and district heating Preferably, the heat exchanger is located down stream the high temperature ESP. At higher gas temperatures often a two-stage arrangement is used, then the ESP is located between the raw gas and the clean gas boiler.
