摘要

Process for the use of residual heat removed in the chimneys of boilers from the combustion of bagasse from sugar cane and improvement in concentration plant. The present invention describes a procedure for use of waste heat (hot gas to 200 u00b0 C) eliminated in the cha Minu00e9s (01) for steam boilers.The gases, initially superheated, originally a feed preheater (03) with spray guns (07) that will dessuperaquecu00ea them and actually saturate them, and then feeds a multiple effect evaporator (12,23,24) that carries out the concentration of the broth or vinasse with "n" effects.This process allows the concentration of the broth or vinasse by evaporators mist type turbulent, especially designed to be fed 100% with the hot gases from the chimneys of the boilers.Describes also a improvement in concentration plant, consisting of a coupling (02) that captures the hot gases disposed in the chimneys of total or partial, and the addition of scrubbers / sprayers (07) that wash and dessuperaquecem with condensed water (17) of these gases, B. In addition to a chimney (11) which removes the non condensable gas dry (10).
