Is Your Recovery Boiler a Production Bottleneck?

Black liquor is one of the most troublesome industrial fuels used for steam and power generation. On a dry basis, black liquor contains 40% to 50% inorganic material, which form a low-melting-temperature “ash” (smelt) ager combustion. Ash deposition on tube surfaces in the upper furnace of recovery boilers is inevitable when black liquor is burned. Deposits grow and restrict flue gas flow if they are not periodically removed from the tube surfaces by sootblowers.

In Kraft Recovery Boilers, Third Edition, a new release from TAPPI Press, readers will find a chapter that discusses the principles of deposition and deposit formation mechanisms and properties (chemical, thermal and morphological). The chapter then examines how deposits form at different locations in the boiler and important factors that govern deposit buildup.

In addition to learning about deposit formation and plugging, readers of Kraft Recovery Boilers, Third Edition will find chapters covering various aspects of recovery boiler technology from chemical principles to black liquor properties, sprays, combustion, char bed characteristics and air delivery.

Like the previous two editions, this book is sponsored by the Recovery Boiler Program R&D Subcommittee of the American Forest & Paper Association (AF&PA) and published by TAPPI Press.  

Engineering, technical, and supervisory staff at pulp and paper mills, as well as technical people working in the field will benefit from this must-have resource.
