  • Black Liquor Recovery Boilers - An Introduction

    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 and supply process steam demands. The design of the BLRB is attributed to G.H. Tomlinson and the first unit having water walls was constructed in 1934 by Babcock Learn More

  • [PDF] Corrosion of superheater tubes in recovery boilers

    Corrosion is one of the main causes of reduced reliability in steam generating systems. It is estimated that problems due to boiler system corrosion cost industry billions of dollars every year. Many corrosion problems occur in the hottest areas of the boiler: floor tubes, water wall, screen, and superheater tubes. Other problematic areas include deaerators, feed water heaters, and economizers.Learn More
