"Strong" black liquor enters the recovery boiler from the brown stock washers containing 65-85% dry solids. The recovery boiler uses strong black liquor as its main fuel and during normal operation functions with black liquor as the only fuel. The cooking chemicals flow out of the recovery boiler as molten salts, or smelt, and are turned into green liquor in the dissolving tank. This green liquor is sent to the recausticizing process for conversion to white liquor. This module describes the components and flow of a recovery boiler liquor system as well as the combustion process of black liquor.
