Black Liquor Recovery Boilers - An Introduction

The sodium sulfate or kraft pulping process was patented in 1884 and accounts for over 80% of all pulp produced in North America. This process would not be economically viable without the black liquor recovery boiler (BLRB). The purpose of the BLRB is to reclaim the spent pulping chemicals in the "black liquor" by the process of combustion and to capture the heating value as steam to generate electricity
