VILLAFLOR, Gloria del V; VELASCO, Jorge W  e  BISONARD, Eduardo R. Calculation Program for Evaluating Pollutants in Powdery and Gaseous Effluents from Melting Furnaces. Inf. tecnol. [online]. 2010, vol.21, n.6, pp.13-18. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642010000600003.

The development of a software package for evaluating the environmental pollution due to gaseous effluents and powders from pirometallurgical processes furnaces is presented. The system consists of hoods to draw gaseous effluents and powders, decantation equipments for coarse particles, gas cooling and powder cleaning, aspiration and unloading ducts, fan and stack. The temperatures are estimated throughout the system, the heights speed and the load losses are corrected. The software performs the energy balances of the process, calculates the área of the cooler, the load losses and the centrifugal fan power. It also allows checking the calculations, simulates extreme situations and obtaining results that save calculation time for a successful decisión making both for the proper function of the system and to establish the correct actions for reducing pollution produced by pirometallurgical processes.

Palavras-chave : gaseous effluents; powders; environmental pollution; melting furnaces; calculation program.
