Cement applications

Concepts for inlet chambers.

Task
The inlet chamber is the connection between rotary kiln and preheater (in general) or the calciner (specifically). This part of the plant is designed to ensure a possibly dust-free transfer of raw material from the static preheater to the dynamic kiln, and also guides the hot kiln exhaust gases into the calciner.
Frequently, the inlet chamber is also fitted with a bypass system.

Demands
Apart from the thermochemical stresses, the inlet chamber is also subjected to considerable mechanical loads due to process-related cleaning operations (e.g. air cannons, Cardox, high-pressure water jets).
Moreover, the use of old tyres as alternative fuel also considerably increases the Redox and thermal shock loading of this plant section.
