Q. Show Corrosion of BFW Pump?
BFW pumps are in high-pressure high-temperature service and may be subject to cavitation and erosion-corrosion. Also overheating of these pumps is always concerned which can be managed by proper operation and circulation of cooling media to the pump suction header.
Low-grade metallurgy shall not be selected for BFW pumps and upgrading to 12Cr is recommended to prevent excessive erosion problem.
