2 GLASS LEVEL PNEUMATIC MEASURING SYSTEM High accuracy level detection, typically within ± 0.1 mm Easy and reproducible height adjustment Easy and quick probe replacement Electrically earth-insulated probe available for furnaces with booster Main Features Turret suitable to support the glass level probe Manually adjustable height with graduated scale and position indicator Water-cooled glass level probe Pneumatic panel Glass Level E.A.G.Le. 2.0 Evo The electronics is fully contained in the process camera Working Principle: E.A.G.Le allows measuring the glass level through the optical reflection of a fixed pointer mounted out of contact with glass How it is made: It is composed of a fixed steel pointer (water-cooled probe) in INCONEL and a video camera (water-cooled) placed in a rigid industrial casing. How it works: It acquires and processes the images through the video camera using advanced algorithms managed by an Artificial Vision software running in the microprocessor control unit. The real and virtual pointer reflected images are acquired at high frequency enabling thus to establish the actual level of the glass with absolute precision. No contact with glass nothing in movement Absolute level measure Easy to install Maintenance-free Self-calibrating Vibration-proof Technical features Measurement Field from -15 to +15 mm Resolution lmage Elaboration Pointer and Camera Cooling higher than ± 0.05 mm 30 frames/sec. demineralized water

4 GAS AND HEAVY FUEL-OIL FIRING SYSTEM The GT Burners series are used in end-fired and cross-fired glass melting furnaces where the combustion chamber is located above the molten glass bath and enclosed in refractory walls. Combustion air is preheated by regenerators before being delivered to the furnace so that the air flow can create the appropriate flame geometry. Further adjustments are possible by controlling the condition of the gas supplied to the chamber. High efficiency low NO x flame EASILY adjustable flame shape and LENGTH Easy angle and position adjustement with our GTBS support Easy to clean and maintain No air leakage between refractory blocks and burners by means of cast iron sealing plates Different sizes suitable to be installed on any regenarative furnace OIL GAS BURNER TYPE FLOW RANGE PIPE PRESSURE RANGE (Ncm/h) ø gas (mbar) Underport MIN MAX MIN MAX GTEF " GTEF "1/ GTEF "

5 Stirrer With BDF stirrer mechanisms it is possible to achieve better quality in glass homogenization and better production flexibility of coloring forehearths. Sliding bracket motion for easy maintenance or refractory parts replacement Different configuration up to 4 stirrers Independent rotation for left/right 4-stirrer group Same rotation or counter rotation for each stirrer Remote electronic control for speed and direction Cat scratch removal system Cat Scratch Removal System: thanks to its characteristics, it allows a complete dispersion of the zircon cord, which is homogenized into the molten glass, thus eliminating the visual defect. Independent rotation clockwise or anticlockwise for each unit Independent speed variation for each unit Controlled by remote control panel Side rotation on the vertical sliding axis for easy refracory unit replacement before after BOOSTER SYSTEM Bottom - Sidewall Medium voltage - Low voltage Pull increase Glass quality increase NO x emission reduction THroat booster Stability of furnace operation Increase of the minimum residence time of glass in the melting area Complete of all necessary installation accessories The throat booster system is a safety system used to avoid the glass freezing in the throat during the furnace heat-up and/or when the production is stopped and no glass is flowing through the throat. Required power: 60 kw approx (during normal operation, the system is switched off) Power supplied by two molybdenum bottom electrodes in glass The electrodes are supported by a special water-cooled holder A thermocouple is installed on the holder to detect the temperature BUBBLER The bubbler principle is to blow a small amount of air into the glass bath in order to obtain a vertical glass current from bottom to top. The air bubbles lift upwards the colder glass from the bottom. It generates big improvement of the glass current Effective push-back batch force Better heat exchange between flames and glass It increases the pull and the glass quality mainly for colored glass melting
