Design and Fabrication of Super Heater Used In Boiler

If rusting is formed on the steel tube then material gets failure or gives less efficient of steam For this reason the tube or material should be de-rusted by grinding wheel By removing this rusted or corrosion particles on super heater tubes tube failures can be arrested and efficiency of steam also increases

Finding the Root Cause of Boiler Tube Failures

Failures result when the tube metal temperature is extremely elevated from a lack of cooling steam or water flow A typical example is when superheater tubes have not cleared of condensation during boiler start-up obstructing steam flow Tube metal temperatures reach combustion gas temperatures of 1600F (870C) or greater which lead to tube failure
