400 tpd end-fired furnace for Nampak Glass in South Africa

In Roodekop Nampak produces returnable and non-returnable glass bottles for the food and beverage industry with the latest glass melting furnaces.The company produces numerous bottle types for the market, ranging from 100 ml up to 1.5 l.

In international comparisons of economical statistical data, Nampak competes with the leaders in the field. In order to bear comparison with these also in the future the new furnace 03 has been built mid of this year. HORN received the order for supplying this furnace together with their partners of the Glass Alliance.

From April to June the new regenerative end-fired furnace was built under the site supervision of HORN. The furnace is designed for an output of 400 tpd of bottles. Due to its special design and a corresponding additional electric heating the multicolour furnace can produce container glass in the colours flint, green and amber. The afore-mentioned additional electric heating has been designed as bottom boosting with 12 electrodes and 2,400 kVA connection power.

Apart from engineering the melting end HORN supplied the entire engineering for the distributing end and the forehearths. Here the new forehearth system GCS 301 has come into operation. It enables Nampak to produce a wider range of products with many job changes. Moreover the new forehearth system by HORN complies with the requirements concerning higher homogeneity of temperatures during production of lightweight bottles in an NNPB process.

In addition to the engineering of the refractories, HORN supplied the entire peripheral equipment for the new furnace, which was set into operation successfully mid of this year.
