Lime Kiln Chemistry and Effects on Kiln Operations

A lime kiln is used to convert lime mud into lime for reuse in the causticizing plant of the kraft recovery process. Many of the problems encountered in lime kiln operations can be related to kiln chemistry, including TRS and SO2 emissions, dusting, ringing and refractory brick thinning. Understanding the composition and thermal behaviour of lime mud and the major chemical reactions involved is...

Thermal Treatment of Mercury Mine Wastes Using a Rotary Solar Kiln

Thermal desorption, by a rotary kiln of mercury contaminated soil and mine wastes, has been used in order to volatilize mercury from the contaminated medium. Solar thermal desorption is an innovative treatment that uses solar energy to increase the volatility of contaminants, which are removed from a solid matrix by a controlled air flow system. Samples of soils and mine wastes used in the expe...

The Reduced Emission Oxygen Kiln

We are pleased to submit our white paper report on the Reduced Emission Oxygen (REO) kiln. The document outlines the basic technology and the operational differences between the REO kiln and a conventional cement plant. We trust that you will find the results as exciting as we do and look forward moving this next generation cement technology to market. The REO kiln represents a paradigm shift i...

Additive Feedforward Control of a Kiln Using Neural Networks

This paper presents an application of Neural Networks to the control of a real system with measurement noise. The details of the system and the implementation of sensor, controller and actuator are described. Saturation in the actuator is present and dealt with. The results of controlling the kiln with Direct Inverse Control and Additive Feedforward strategies are presented and compared. Proble...
