Rotary kiln as an important calcination equipment, Rotary kiln burner is one of the essential components, many people are familiar with the rotary kiln equipment, but the understanding of the burner is very rare. Chaeng Machinery is the most professional rotary kiln manufacturer, with rich experience in rotary kiln production, and today we will ask chaeng technical staff  explian details the structure of the rotary kiln burner and burners to adjust the notes.

The burner is composed of a burner tube, a coal hood hose, a primary air hose, a burner moving trolley, and a fuel oil burner. Burner tube is the core of which burner, its performance is good or bad, basically determines the performance of the burner, so the burner is also named by the form and type of fuel injection tube is determined.

The burners are divided into single duct burners and multiple duct burners. Single-channel burner is the rotary kiln early coal-fired burner, single duct that only one coal duct, a high air volume, not suitable for burning low-quality coal and anthracite.

A multi-burner burner is a combustor with a gas delivery duct greater than or equal to three. Such as three wind tunnels (there is a coal air duct, two air duct - the wind and the wind) and four air duct (a coal air duct, the three air duct - the wind, the wind and the central wind ), Their low air volume, high wind speed, large wind capacity secondary wind. The wind speed, air volume can be adjusted to adapt to low-quality coal and anthracite, the modern rotary kiln, especially the new dry kiln production line often selected burner.

Burner into the kiln, the high temperature point after the shift, the tail temperature increased, the kiln sealing device adverse; pull out, the burner and the kiln mouth from the distance, the flame forward, the kiln clinker temperature, Cylinder and burner service life of the impact.

Rotary kiln burner not only provides fuel and oxidant for combustion, but also the main power plant for flame forming. Therefore, the choice of burner and the precise process all play an important role in clinker calcination and cost reduction.
