What characteristics should a good quality pulverized coal burner have? The combustion acquisition of pulverized coal burners is closely related to the two aspects of flow and radiation. The main factors affecting pulverized coal airflow Tags: Boiler pulverized coal burner pulverized coal burner tilted iron pulverized coal burner is the main component of pulverized coal combustion equipment, which delivers pulverized coal and the air required for combustion to the furnace, forming a reasonable airflow structure so that the fuel can burn quickly and stably. It has a specially designed multi-stage inlet air supply guide structure that can generate high-temperature vortex for pulverized coal in a short time. The combustion acquisition of fly ash burners is closely related to the two aspects of flow and radiation.
The main factors affecting pulverized coal airflow:
(1) Fuel characteristics
(2) Furnace cooling conditions
(3) Initial temperature of pulverized coal airflow
(4) Primary airflow and wind speed
(5) Boiler workload. Normal fire is applicable to a distance of 500 to 1000 mm from the primary air nozzle. Premature ignition will burn the burner nozzle or cause burner nozzle slag. Lighting too late will make the fire unstable, the machine will not burn completely, the flue gas temperature at the furnace outlet will rise, and slagging will form at the furnace outlet.
The basic conditions for a good quality pulverized coal burner are:
(1) Simple and compact structure with low ventilation resistance.
(2) The outlet airflow has sufficient disturbance to enable good mixing of the airflow.
(3) The 1st to 2nd air outlet section must ensure the appropriate 1st to 2nd air speed.
(4) The distribution of pulverized coal along the outlet section must be uniform.
(5) The diffusion angle of the pulverized coal airflow can be adjusted arbitrarily within a range to adapt to changes in coal.
