The use of computer automatic control and sharing of the production data of the gas station and the melting furnace is conducive to the stable operation of the glass melting furnace and the stable control of the furnace temperature, and is the development direction of the gas production technology.

Conclusion (1) Theoretical analysis shows that the number of swirls S in the furnace is the ratio of the actual rotational speed to the average rising speed in the furnace, and its size will affect the thermal deviation of the high temperature heating surface in the horizontal flue.

(2) In the case of considering only the influence of the secondary air distribution method on S, when the wind speeds of the secondary air nozzles are equal, S will be minimized; the wind distribution mode deviates from the equal distribution air level, and S is larger; In the case of considering only the influence of the primary and secondary wind speeds on S, when the first and second wind speeds are equal, S will reach the minimum value. For example, from the perspective of the secondary air and the primary air momentum ratio P, there is a P. The value minimizes G; as the boiler load decreases, the number of swirls S in the furnace increases.

(3) The thermal deviation test results of a reheater of a 300MW boiler show that under the same load, the influence of the change of the secondary air distribution mode is obvious, and the maximum thermal deviation coefficient and standard deviation increase with the increase of S. S and S are also the smallest when the air is equalized, which is consistent with and corresponds to the theoretical analysis of the influence of the secondary air distribution method on S.

(4) The thermal deviation test results of a reheater of a 300MW boiler show that as the boiler load decreases, the number S of swirling in the furnace increases, and the maximum thermal deviation coefficient increases with the increase of S, which is related to the boiler load. The theoretical analysis results of S influence are consistent and corresponding.
