SORG Group completed a furnace reconstruction with redesign for The Branch of Malaya – Vietnam Glass Limited.
After more than 14 years of successful operation, the VN1 furnace, designed and delivered by SORG in 2011, was due for reconstruction. As part of the reconstruction of the existing end-port furnace, the task was to increase the melting capacity of the furnace from 280 to 340 tonnes per day, while maintaining the melting area and reusing the existing tank steel as far as possible.
Increasing the melting capacity to 340 tonnes per day for containers in all glass colours required the installation of a powerful melting and barrier booster. This involved changes to the furnace design (on the steel and refractory sides) in both the melting end basin and the furnace superstructure to adapt the furnace geometry to the changed conditions. To increase the dwell time of the melt in the furnace and to ensure glass quality, it was necessary to install a SORG Deep Refiner SDR®, which meant changing the throat and riser area on the steel and refractory side.
The engineering for the reconstruction, including the design adjustments as part of the melting capacity increase, was carried out by SORG. The increased melting capacity and tonnage at the forehearth necessitated the adaptation of the glass conditioning to a SORG STW distribution channel and four SORG 340S+® forehearths.
SORG’s scope of supply included the provision of the components and parts required for the reconstruction and expansion, including the SCADA system.
The steel and refractory construction, assembly of the equipment parts including heating up, filling and commissioning were carried out under the supervision of SORG.
