The kiln burner is an integral component of a rotary kiln system, part of the pyroprocessing system, serving to optimize the combustion of fuels and heat release in the kiln. The burner system is used for the sole purpose of providing heat to the rotary kiln to activate the chemical reactions that yield cement clinker [ 6 ].

Uniflow Burner – for efficient thermal processing
FeNi Burner. Our FeNi Burner is a variant of the Uniflow Burner, as it has a third channel in which secondary air is processed. This makes it a less compact machine, but despite this downside, it is able to produce more complete combustion of fuels. These two burners aim to amplify your rotary kiln experience.

Refractories for Portland Cement Manufacturing | SpringerLink
Kiln is the heart of the cement plant where the clinkerization takes place at high temperature. The kiln is a cylindrical horizontal tube with a very little inclination of 1–2 degrees. The kilns have a diameter of 3 to 7 meters and length of 50–100 m. The kiln rotates on its horizontal axis at a speed of 1.5–4 RPM.

Systematic evaluation of pyrolysis processes and
A flame curtain pyrolysis kiln seeks to reproduce these conditions by operating the kiln under conditions such that the pyrolysis gases produced are oxidised by a flame, which is sustained over the surface of the kiln (Schmidt et al., 2014). The kiln design ensures that oxygen is consumed in the flame and therefore cannot reach the biochar.
