Optimization of the process of cooking and drying of brick

Abstract

The construction materials play an enormous part in the economy of the country; this industry comprises a very varied range of products going of simple pottery passing by brick of construction until the technical porcelain and the industry of cements. As, this production takes a so important rise as the realization of manufacturing plant becomes a daily reality. This realization of quite quantitative factory that qualitative depends on the availability of a raw material of quality, means of production in good knowledge and operating condition to make allowing a perfect control of the process. Considering, the enormous part which plays the construction materials in particular the bricks of construction in the economy of the country. We were interested to make a study concerning the production unit of bricks of Boudouaou (east of Algeria) on the technological, thermal and economic level since the essential study is made on the thermal part in order to calculate the acceptable mode of cooking and to calculate the combustion of gas. The study of the heat balance enables us to know how calculations can be carried out and of knowing how and the energies brought to the furnace spent are consumed. This study enabled us to make a saving in gas in the order of 63.5 m³/h and to make a profit of energy of 266.37 kJ/kg of product and to obtain a better use of the drier and furnace with a possible maximum thermal efficiency
