A pulverized coal burner is, as the name suggests, a device that allows pulverized coal to burn fully in a short period of time, generating a high temperature vortex. Pulverized coal indicates coal with a particle size of 0.5 mm or less and is the most commonly used additive in cast iron molding sand. Compared with traditional lump coal, pulverized coal has the advantages of small density and large surface area, which makes it easy to transport pulverized coal pneumatically. The disadvantage is that pulverized coal is easy to form self-flow and easy to leak powder when the equipment is not tight.
According to the usage, the pulverized coal burner is generally divided into 1, coal burner for rotary kiln 2, coal burner for boiler 3, coal burner for asphalt mixing station.
Compared with coal-fired burners and heavy oil burners, coal-fired burners have obvious advantages in many aspects:
1. pulverized coal combustion in the high temperature zone of the pulverized coal combustion burner for a long time, high combustion efficiency, direct discharge of the flue without black smoke, steam-like white smoke
2. Pulverized coal combustor heating temperature rise time is shortened, high thermal efficiency, and the quality of coal combustion requirements are low, the coal type is widely applicable, high economic efficiency
3. The coal-fired powder burner is easy to ignite and heats up quickly, and the working efficiency is greatly improved.
4. The air supply volume and coal input volume of the pulverized coal burner can be changed according to the need, and the furnace temperature and fire length can be adjusted within a wide range to meet the actual demand.
5. The internal temperature of the pulverized coal burner is uniform, and the heating surface is poor.
EBICO is one of the well-known manufacturers who developed the special pulverized coal burner for asphalt mixing plant at an early stage. This series of burner has wide fuel adaptability and can be applied to pulverized coal, natural gas, light oil, heavy oil and other fuels at the same time. The combination of graded fuel combustion and graded air supply effectively reduces nitrogen oxide emissions.
