ABSTRACT:
Apparatus and method for reclaiming heat from batch digesting operations including two fluid-to-fluid exchangers fluidically interconnected to allow the passage of an inert fluid between the heat exchangers. The inert fluid passes through the inaccessible regions of the heat exchangers promoting the exchange of heat between spent digester cooking fluid and fresh digester cooling fluid without scaling, clogging or blocking the inaccessible regions of the heat exchanger.
