The trajectory of glass particles in the actual melting furnace glass flow can be determined by isotope tracing method. Firstly, isotope particles are put into the batch, and detection devices are arranged around the furnace to locate the movement process of isotope particles and track the movement track of isotope particles.

The design service method of glass furnace has high technical requirements and is difficult to realize, so it is rarely used in practical engineering. Another method is contrast method, in which contrast agent is added by pulse method during feeding. One side of the glass kiln wall is provided with a gamma-ray emitting device, and the other side is provided with a synchronous receiving device, and both sides scan the glass melt of the glass furnace synchronously. Because the contrast element has strong ability of absorbing gamma rays, two-dimensional electronic images of the furnace can be obtained, and the dynamic concentration distribution information of refueling in the glass melt can be obtained through image analysis.

Among the measured methods, the thermal measurement and heat balance calculation of the whole glass furnace are mature. This measurement task is like a comprehensive physical examination conducted by a hospital. In the project of temperature measurement, the temperature on the surface of the furnace can be measured to determine the heat dissipation intensity. The measured data can not only provide the basis for energy saving of the furnace, but also indirectly determine the flow pattern and working condition of the molten glass inside the furnace.
