Daily Question (January 30)

The burner is a key component of the combustion equipment in coal powder boilers; its function is to feed the coal powder and the air required for combustion into the furnace, and to create an optimal airflow pattern that enables the fuel to ignite quickly and burn steadily. The essential requirements for a good burner are: (1) The outlet cross-sections of the primary and secondary air should ensure an appropriate wind speed ratio between them ； (2) The outlet airflow has sufficient turbulence to ensure good mixing of the airflow ； (3) The diffusion angle of the coal powder airflow can be adjusted arbitrarily within a certain range to meet the requirements resulting from changes in coal type ； (4) The distribution of coal powder along the outlet cross-section should be uniform ； (5) The structure should be simple and compact, with low ventilation resistance.

What is the function of a coal powder burner? What conditions are required? The burner is a key component of the combustion equipment in coal powder boilers; its function is to feed the coal powder and the air required for combustion into the furnace, and to create an optimal airflow pattern that enables the fuel to ignite quickly and burn steadily. The essential requirements for a good burner are: (1) The outlet cross-sections of the primary and secondary air should ensure an appropriate wind speed ratio between them ； (2) The outlet airflow has sufficient turbulence to ensure good mixing of the airflow ； (3) The diffusion angle of the coal powder airflow can be adjusted arbitrarily within a certain range to meet the requirements resulting from changes in coal type ； (4) The distribution of coal powder along the outlet cross-section should be uniform ； (5) The structure should be simple and compact, with low ventilation resistance.

The coal powder burner features a specially designed multi-stage, multi-nozzle air supply and guidance structure that enables the creation of high-temperature vortices in the coal powder in a short time. It offers advantages such as complete combustion, high heat utilization efficiency, smoke and dust reduction, energy savings, improved working conditions, and reduced labor intensity. It is an ideal product for energy conservation and environmental protection, and is highly popular among customers. High-efficiency coal powder combustion technology and low-NOx combustion technology are two contradictory techniques. To reduce NOx generation and emissions, it is essential to keep the temperature in the combustion zone from being too high. However, low-temperature combustion affects the combustion rate of coal powder; the goal is to coordinate the use of these two techniques to achieve the best overall results, which in practice requires controlling the entire process of coal powder combustion. It ensures the stability of coal powder ignition, has a lower combustion temperature, and at the same time provides a sufficiently long combustion time at a certain temperature to ensure complete combustion.
