Rotary kiln - Wikipedia

This turns the kiln very slowly, but enough to prevent damage. Internal heat exchangers. Heat exchange in a rotary kiln may be by conduction, convection and radiation, in descending order of efficiency. In low-temperature processes, and in the cooler parts of long kilns lacking preheaters, the kiln is often furnished with internal heat

The cement kiln - Understanding Cement

Wet process kilns. The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter. It has to be long because a lot of water

Modeling of Rotary Kiln in Cement Industry

Ongoing maintenance and operation of the rotary kiln are vital. It is very expensive,[2] be-cause that would stop the kiln production. After having a comprehensive model of the process, we can create a better performance of the kiln, and the model can be used for operator training by experiencedoperators expert in the industry used [3], and eventually a reduced energy consumption in the cement

Real-Time Modelling of Dynamic Behaviour for Clinker

The authors’ objective is to estimate a dynamic behaviour of Clinker Rotary Kiln when the state variables of the process can be measured only at a few locations. These variables (gas, clinker temperatures and clinker mass distributions) are eorated with the help of heat, pressure and mass balance partial differential equations. The

Scrubber - Wikipedia

Wet scrubbers can also be used for heat recovery from hot gases by flue-gas condensation. In this mode, termed a condensing scrubber, water from the scrubber drain is circulated through a cooler to the nozzles at the top of the scrubber. The hot gas enters the scrubber at the bottom.

Energy auditing and recovery for dry type cement rotary

Process description and data gathering. Rotary kilns are refractory lined tubes with a diameter up to 6 m. They are generally inclined at an angle of 33.5°, and their rotational speeds lie within 12 rpm. Cyclone type pre-heaters are widely used to pre-heat the raw material before it enters the kiln intake. In a typical dry rotary kiln system, pre-calcination gets started in the pre
