REDUCCIÓN DE EMISIONES DE CO2 MEDIANTE LA MEJORA DEL AISLAMIENTO DE LA CAMPANA DE SECADO EN LA FABRICACIÓN DE PAPEL

Abstract

Pulp and paper industry is an energy-intensive production process, both electricity and heat. This process is fundamentally a mechanical process by this fact consumes most of the energy as electricity (pulp production, machinery drive, vacuum systems). Another significant portion of energy consumed is used in the form of thermal energy for drying paper, mainly in the dryer section, through a hood that insulates the drying section. This hood may lose insulated sealing that can cause significant energetic losses that affect to emissions CO2 per product. This paper analyzes the current state of a closed hood to quantify losses at the facility insulation fault, improper adjustments of parts and impairments access systems. To carry it out we have used thermographic systems, which show faults close and damage caused in the installation with the opening and closing thereof for the normal operation and maintenance issues of the section. We have identified poorly insulated or not engaged properly areas, estimate the energy losses depending on the outside temperature of manufacturing hall, have compared this energy loses with the thermal energy consumption used to dry the paper and have looked for the influence of this losses on emissions CO2 per product.
