Abstract
This work presents an original method and an automated installation to recover by combustion the waste gas obtained in the
ignition process of xylites in rotary kiln. The flue gas resulting from the combustion of waste gas, with light fuel support are
used in the technological processes of obtaining activated carbon, satisfying the conditions where the oxygen content does not
exceed 0.3 % vol. and the temperature is above 1200°C, conditions imposed by the Project Manager of the European project
LIFE 02. Our automated installation consists in a combustion chamber and a heat exchanger, which along with a rotary kiln and
an activation reactor build the technological installation called “ENVACTCARB” of this project. The design of our automated
installation was done by running a computer program in order to calculate the combustion parameters and based on material and
energy balances. The experiments were carried out in two stages: preliminarily, to characterize the liquid fuel combustion in the
pilot installation and secondary, in the technological installation. The preliminary experimental results, presented as a comparison
between the variants of light fuel burning, with and without using additives, show getting a complete combustion having low
emission of pollutants and the oxygen content not exceeding 0.3% volumes. The experimental results performed in the
technological installation certified the use of the automated installation for waste gas recovery through combustion.
