Electrical boosted glass melting tank is efficacious method which can raise melting capacity of furnace. This paper describes an investigation on one factory's electrical boosted glass melting tank. A physical model of electrical boosted glass melting tank was established on the basis of theory of similarity. On the basis of the observation on current patterns and measurement of the temperature distribution. Electrode arrangement, power distribution, melting capacity, the depth of melting tank, the length of electrode was investigated. On the basis of the measurement of electric current and electric voltage, the glass electric resistance of electrode was determinated. The transformer secondary specific property and specifying electric boosted melting equipment type was determinated in advance.
