Determination Of Trace Impurities In A Furnace Atmosphere At Operating Temperatures

The dripping phenomenon in the silica superstructure refractories of a gas-oxy furnace is a common in the glass industry. The reason for this has been established to be from the attack of silica by alkali present in the vapor phase from the glass composition. Many techniques can be used to analyze gas composition at room temperature, but at temperatures as high as 1600C there are very limited choices. The method used for the determination of particulate emission from a stationary source was chosen for this work because the method is simple and portable. The objective for this work is to develop a reliable, portable, easy-to-use method to analyse the concentration of alkali in the vapour phase of a gas oxy furnace at operating temperature.
