PROCESSO PARA RECUPERACAO DE ENERGIA TERMICA GERADA NA PRODUCAO DE POLPA TERMOMECANICA

摘要

A method of recovering the thermal energy contained in the pressurized steam utilized during the production of thermomechanical pulp. The steam is applied to the primary side of a heat exchanger with water supplied to the secondary side in order to produce hot water. The water is vaporized to produce clean steam. The clean steam is then utilized to at least a first steam group of the drying sections of a paper manufacturing machine without increasing the pressure of the clean steam.
