Impact of coating layers in rotary cement kilns:

2020-3-1  The main component of cement, the so-called cement clinker, is mainly produced in rotary kilns after the drying and calcination process. The raw material, mostly limestone and clay, is ground, dried, deacidified in a pre-calciner and then burnt in the rotary kiln to produce cement clinker.

Impact of coating layers in rotary cement kilns:

Abstract. In this study CFD simulations of an industrial scale rotary kiln for cement clinker production are conducted. A solid layer of agglomerated clinker material, which adheres to the kiln wall and forms a stable coating of variable thickness during kiln operation, is considered in the simulations of the furnace.

Stabilization of Kiln Coating Industrial Efficiency

2017-9-13  Stabilization of Kiln Coating. Coating formed on the brick working surface in the kiln burning zone lowers the shell temperature, reducing radiation heat losses and protecting the refractory material. Unstable coating easily leads to problems with the refractory material and causes loss of energy and disturbs stable kiln operation.
