The Operation Status Of 600T/D Float Glass Furnace And Maintenance Measures And Technology Improvement Research

Float furnace is the key to the glass production thermal technology equipment,also is the main part of the energy consumption.Especially in the current energy shortage and Price rise increasingly and fierce competition in the market trend period,furnace construction of high-quality,low energy consumption is an important subject in furnace engineering technical personnel.Dezhou Jinghua group float second-line 600T/D furnace operation throughout the nine years,in excess of eight years design furnace age,become Dezhou Jinghua group fuel the most species,the largest furnace and the longest operation furnace.In this Thesis,the author through the angle of the combination of practical application and theoretical analysis,the main process indexes,furnace technology index,Daily operation of furnace,problems in the operation of the furnace and so on four aspects in detail elaborated and theoretical analysis,And according to the practical experience of oneself improvement opinions and Suggestions are put forward.The author through the analysis of the practice and drawn six aspects conclusions :Three thermal technology equipment to match each other to exert better furnace melting potential.Ladder type bottom structure and gradual clarify technology,bottom bubbling technology,petroleum coke powder application technology,optimization of the melting process curve and other new technologies to the melting part of the original design concept of a profound effect,will further update and improve the original design idea,to design a high-quality and high-efficiency furnace.Selection of flame space heat load and surface heat strength of two design parameters to the flame space combustion efficiency,radiation heat transfer ability to effectively react to the same furnace in different melting capacity through certain quantitative calculation of forecast.Material selection and design of the furnace wall brick,to undertake choosing according to age of furnace and the actual usage.Selection of wall brick bond according to the age of furnace requirements can choose different fused brick thickness,sintering chrome corundum material as the wall brick still needs careful bond.Petroleum coke powder on the erosion mechanism of alkaline material is mainly due to its combustion products of SO₃,V₂O₅,and alkaline materials of CaO and MgO style composition under the high temperature reaction,generate eutectic,easy peeling,large volume change of dicalcium silicate（C₂S）,shannonite（CMS）,magnesium olivine（M₂S）,manganolite（C₃MS₂）eutectic mixture.According to the different parts of furnace erosion situation and the structure characteristics of furnace and adopt the new technology,new material and new method to comprehensive maintenance from the furnace internal and external,to improve the maintenance efficiency,reduces the labor intensity,ensure the safe operation of the furnace.Furnace technical personnel should be good at discovering the shortcoming and defects in the furnace operation,through timely study and master the development and application of new technology,combined with the actual situation of continuous self reasonable optimized design scheme,both to reduce staff labor intensity and ensure safe operation,and can promote the furnace to better achieve the high quality,high efficiency,low consumption,long age of furnace design goal.
