The boiler Air Nozzle is the air distribution device of the boiler, which plays a key role in the safe and economic operation of the boiler.

The purpose of the boiler air nozzle:

Generally speaking, the coal particles below 10mm are generally burned, and the pulverized coal is blown up by the wind blown from the air nozzle to form a boiling combustion. Generally hundreds of nozzles are arranged at the bottom of the furnace with an interval of 20-750px, which can distribute the air evenly, ensure the fluidization of the entire furnace, and avoid local coking.

Features of boiler air nozzle:

The characteristic of the small boiler air nozzle is that the nozzle has a small aperture and good air distribution uniformity. However, the wear phenomenon caused by the small design spacing is more common. The characteristic of the big nozzle is that the nozzle has a large aperture, and the turbulence intensity is greater after reaching the critical fluidization. The design spacing is large, so it can effectively avoid the wear caused by the nozzle blow, so it has a long life.
