Achievements

Flexible use of the boiler with a shorter start-up time.

• Reduction in warm start-up time by 50 % (<1 hour)
• Reduction in start-up oil consumption by 25 %

Boiler design

• Once-through steam generator built 1964
• Two pass slag-tap furnace
• 120MWel
• Main steam: 376 t/h at 535 °C and 174 bar

Scope of Supply

• Process engineering for the installation of a recirculation on a once-through steam generator
• Retrofitting of separation vessel and circulation system by modifying suction and discharge of pipes, fittings, pump, expander, vents and drains, heat-up and evaporation economizer line
• Supplement of steel structure such as platforms, stairs, brackets
• Modification in I & C and boiler protection
