GUTIERREZ-GUALOTUNA, Eduardo Roberto; ARZOLA-RUIZ, José  and  ALMEIDA-MERA, Juan Carlos. Modeling for the operation of the firewood gasification in downdraft installations. Ingeniería Mecánica [online]. 2018, vol.21, n.3, pp.117-123. ISSN 1815-5944.

Optimal operation of energetic installations must considerably influence on its efficiency. By this, the objective of the present paper consists in the definition of the required models structure for the operation of downdraft gasifiers and its identification based on systemic analysis, it identification and the determination of the better adjustment type of model. For the models identification an experimental installation was constructed using, between other biomasses, firewood. Starting from an 3N experimental plan, with three replicas, needed models were identified helped by artificial neural networks and regression techniques. The best results were obtained using neural network, being therefore the most advisable in the preliminary stage of the process of the adaptive construction of operation models of the studied process.

Keywords : operation of technological processes; systems analysis; renewable energy sources; artificial neural networks; non-lineal regression.
