Rotary Kiln Optimization

Business Problem

The control system in clinker production is focused on productivity and efficiency, while assuring the desired quality of byproducts.


The challenge is to make sure that production goals are achieved, pollution impact kept within limits and fuel consumption minimized, while complying with environmental, thermo-dynamical and mechanical constraints.

SentianController solution

Using SentianController, process variables such as cyclones, calcination area, oxygen concentrations, carbon dioxide and nitrogen oxide levels, together with the temperatures at the top and bottom of the pre-heater tower can be optimized along with fan speed and fuel charge rate. Smoke chamber temperature, kiln torque and burning zone temperature can also be controlled.
