The chemical recovery boiler utilizes the black liquor which is the waste liquid coming out from pulp in paper industries. Soot blower is one of the major components required to clean the sediments deposited on boiler tubes which affects the heat transfer. Several issues like steam leakage, lance tube bending, ash deposition on lance tube and corrosion are frequently reported among the 28 soot blowers of SPB Ltd. In this project, the problems that occurring in soot blowers identified and analyzed. The problems are eliminated by the changing of material from stainless steel (310) to magnesium alloy (AZ91D). Solutions for corrosion, ash deposition and steam leakage are given for proper functioning of the soot blowers in the chemical recovery boiler.

Abstract:

The chemical recovery boiler utilizes the black liquor which is the waste liquid coming out from pulp in paper industries. Soot blower is one of the major components required to clean the sediments deposited on boiler tubes which affects the heat transfer. Several issues like steam leakage, lance tube bending, ash deposition on lance tube and corrosion are frequently reported among the 28 soot blowers of SPB Ltd. In this project, the problems that occurring in soot blowers identified and analyzed. The problems are eliminated by the changing of material from stainless steel (310) to magnesium alloy (AZ91D). Solutions for corrosion, ash deposition and steam leakage are given for proper functioning of the soot blowers in the chemical recovery boiler.
