✦ Synopsis

The purpose of black liquor in most kraft mills today is when it is burned in Tomlinson boilers to produce steam for on-site heat and power and to recover the inorganic chemicals for reuse in the process. Globally, the black liquor generation rate is about 85,000 MWfurl with nearly 50% of this in North America. The majority of presently installed Tomlinson boilers will reach the end of their useful lives during the next 5-20 years. As a replacement for Tomlinson-based cogeneration, black liquor-gasifierlgas turbine cogeneration promises higher electric efficiency, with prospective environmental, safety and capital cost benefits for kraft mills. Several companies are pursuing commercialization of black liquor gasification for gas turbine applications.

This paper presents results of detailed performance modelling of gasifierigas turbine cogeneration systems using different black liquor gasifiers and modelled on proposed commercial designs.
