Análise da influência das variáveis da caldeira de recuperação química no sistema de abate do material particulado da indústria de celulose & papel

Abstract

This research describes the planning, the phases of execution and the troubles of the industrial experiment carried out for cellulose and paper industry. It was focused on the context of the chemical recovery. The experimental matrix was formed using three factors of control: pressure and temperature of the black liquor and pressure of primary air with two levels each, center points and faced star points. The emission tax of particulate material was defined as response variable for the experimental research and its value had been gotten using isocinetic measurement. The planning and the results had been generated by software MINITAB v.13, using the Planning and Analysis of Experiments - DOE and also the Surface Response Methodology - SRM, as statistical technology of analysis. The mathematic model didn’t reach the expected adherence but the research provided the possibility of improvement and procedural optimization. It fulfilled the specific objectives and part of general objective. The functional workgroup and academic staff added had improved their skill by the unknown research carried through for the boiler of chemical recovery Stein ET Spanish Roubaix and precipitator electrostatic Fläkt type FAC-2828-6070-3.
