For example, energy conservation and emission reduction can be achieved by optimizing combustion technology, improving combustion efficiency, reducing pollutant emissions, etc.; at the same time, with the help of intelligent control technology, functions such as remote monitoring and automatic adjustment of the burner can be realized to improve the convenience and safety of use.

[0003] For the existing flat wall - attached flame burner, reference can be made to the Chinese utility model patent with the authorization announcement number CN217763414U, which discloses a high - speed low - nitrogen burner with a flat - shaped flame. "It includes an air box, in which an air pipeline is arranged, and a number of through - holes for communicating with the inside of the air box are arranged on the air pipeline. A central gas gun and an ignition gun are arranged inside the air pipeline. The front ends of the central gas gun and the ignition gun both penetrate through a flame - stabilizing device, and the flame - stabilizing device is arranged at the port of the air pipeline. The port of the air pipeline is arranged at the port of the air box, and an auxiliary combustion box is arranged at the port of the air box. Inside the auxiliary combustion box, a rectangular spray cavity connected to the port of the air box is arranged. Two inclined surfaces that gradually contract the port of the rectangular spray cavity are symmetrically arranged inside the rectangular spray cavity. A number of gas pipelines are arranged on the auxiliary combustion box, and each gas pipeline is provided with a first spray port and a second spray port. A number of first spray ports are arranged inside the rectangular spray cavity near the air - box end, and a number of second spray ports are arranged around the port of the rectangular spray cavity."
