Black liquor power generation system, black liquor power generation method, and black liquor power generation system remodeling method

摘要

PPROBLEM TO BE SOLVED: To provide a system and method of power generation using black liquor and a method of modifying the system of power generation using black liquor that can definitize regeneration energy using black liquor and improve power generation efficiency. PSOLUTION: There is provided a second steam generation means (exhaust heat recovery boiler 16) of a system different from a first steam generation means (black liquor recovery boiler 13) for generating steam by burning black liquor generated in a production process (an evaporator 8 or the like) for manufacturing paper from wood, and steam generated at the second steam generation means (the exhaust heat recovery boiler 16) is used as heating steam.
