Pulverized coal burner

Pulverized coal burners are designed to send pulverized coal and air mixed flow into the furnace in a favorable manner, creating a favorable aerodynamic field, ensuring timely ignition, strong combustion, clean combustion, and good burnout of the pulverized coal flow. Pulverized coal burners are divided into two types: direct flow burners and swirl burners.

Characteristics of once-through pulverized coal burner:

◆ Non rotating, small jet expansion angle, small entrainment capacity, poor ignition performance of a single burner, and poor furnace fullness;

◆ The jet has slow attenuation, long range, and good mixing in the later stage, which is conducive to the burnout of pulverized coal;

◆ Adopt four corner tangential arrangement, ignite each other, ignite well, and mix strongly.

Characteristics of swirl burner:

◆ When pulverized coal airflow or hot air passes through the hydrocyclone, it rotates and forms a rotating jet after being ejected from the nozzle;

◆ The use of rotating jets can form a high-temperature flue gas reflux zone conducive to ignition and strongly mix the air flow.

Xuzhou Jieneng Electric Power Co., Ltd. is a high-tech enterprise engaged in the development and production of pulverized coal burners on a large scale in China, and has been continuously developing and expanding through market testing. The main products include: pulverized coal burners, wear-resistant pipes, wear-resistant elbows, heat-resistant steel castings, wear-resistant steel castings, and so on. The company adopts centrifugal casting, investment casting, static casting, and precision casting with advanced Chinese standards to produce high-strength weldable rare earth wear-resistant steel, high-temperature pressure-bearing rare earth heat-resistant steel, and auxiliary equipment for power stations.
