Abstract:Steklo predstavlja trajnostni produkt, saj je njegova popolna možnost recikliranja ključen dejavnik v zmanjševanju okoljskega vpliva. Možnost ponovne uporabe stekla ne le zmanjšuje količino odpadkov, ampak tudi ohranja naravne vire, saj recikliranje zmanjšuje potrebo po novih surovinah. Med procesom pridobivanja-taljenja stekla nastane kar nekaj stranskih produktov v obliki dimnih plinov. Ti nastanejo pri zgorevanju zemeljskega plina s kisikom in pri razpadu surovin za vnos alkalijskih in zemljo alkalijskih oksidov v obliki karbonatov, ki imajo zelo visoko temperaturo (okoli 1400 °C). Te pline je potrebno pred vstopom v toplotne izmenjevalce voda-zrak ohladiti na 400 do 500 °C. Dimne pline lahko ohlajamo na dva načina: z vpihovanjem hladilnega zraka in (ali) z vpihovanjem vodne megle v tok dimnih plinov. Med izvajanjem diplomske naloge smo ugotavljali razliko med porabo energije v primeru, ko pline ohlajamo samo z zrakom ali z vodno meglo. Prav tako smo primerjali izmerjene količine s teoretično izračunanimi. Pri teoretičnem izračunu smo upoštevali povprečne vrednosti fizikalnih lastnosti plinov v dimnih plinih za dane temperaturne intervale. Izračunali smo masno bilanco peči in hladilne komore, ter potrdili oz. ovrgli zakon o ohranitvi mase. Diplomska naloga je nastala v sodelovanju s Steklarno Hrastnik, d. o. o.. Vse meritve so potekale na G – peči, ki se nahaja v poslovni enoti Vitrum.

Title:Energy and mass balance of flue gases cooling in quench chamber after leaving the oxy -fuel melting furnace
Abstract:Glass is a sustainable product, as its complete recyclability is a key factor in reducing environmental impact. The possibility of reusing glass not only reduces the amount of waste, but also conserves natural resources, as recycling reduces the need for new raw materials. During the actual glass extraction-melting process, a number of by-products are generated in the form of flue gases. These are formed during the combustion of natural gas with oxygen and during the decomposition of the raw materials for the introduction of alkaline and alkaline earth oxides in the form of carbonates, which have a very high temperature (around 1400 °C). These gases need to be cooled to 400-500 °C before entering the water-to-air heat exchangers. Flue gases can be cooled in two ways: by blowing cooling air and (or) by blowing water mist into the flue gas flow. During the implementation of the diploma thesis, we determined the difference between energy consumption in the case of cooling gases only with air or with water mist. We also compared the difference between the measured quantities and the theoretical calculation. For the theoretical calculation, the average values of the physical properties of the gases in the flue gas for the given temperature ranges were taken into account. We also calculated the mass balance of the furnace and the cooling chamber and confirmed or refuted the law of conservation of mass. The diploma thesis was prepared in cooperation with Steklarna Hrastnik, d.o.o. All measurements were carried out at the G – furnace, located in the Vitrum business unit.
Keywords:glass, glass furnace, natural gas combustion, flue gases, flue gas cooling, energy balance, mass balance.
