In contrast method, contrast agent is added by pulse method during feeding, and a gamma-ray emitting device is arranged on one side of the glass kiln wall, and a synchronous receiving device is arranged on the other side, and the glass melt in the glass furnace is synchronously scanned on both sides. 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.


The trajectory of glass liquid particles in the actual glass kiln construction flow can be determined by isotope tracing method. Firstly, isotope particles are put into the batch, and detection devices are arranged near the furnace to locate the movement process of isotope particles and track the movement track of isotope particles. This method has high technical requirements and difficult implementation, and is rarely used in practical engineering. The temperature of designated points in the melting furnace was measured by optical pyrometer through observation holes in different parts, and the information of glass melting conditions in large-scale float glass melting furnace was indirectly obtained. This method can sometimes achieve good results. This technology is one of the practical and feasible testing technologies, and the infrared image can also be used to verify the calculation results of the temperature distribution on the outer surface of the crown obtained by numerical simulation.


After the molten glass in the furnace is shut down and emptied, to verify the active form of the molten glass can also judge the general situation of the molten glass form during the operation of the furnace by observing the washing marks of the molten glass on the bottom of the glass furnace and the refractory on the tank wall, which provides a basis for analyzing and formulating the further improvement direction of the furnace.
