SITSON CFBC BOILER

Key Features

  • Excellent turn down ratio without auxiliary.
  • Internal circulation of bed material by gravity and solid recycle with FD and PA fan air.
  • High solid collection efficiency
  • Very thin refractory lining.
  • More fuel flexibility.
  • Low Sox and Nox emission levels.

Advantages of SITSON CFBC Boiler

  • Low auxiliary power consumption compared to other boilers.
  • High combustion efficiency
  • Less start up time and low operation costs.

Higher Reliability

  • Less erosion rate so reduced maintenance cost.
  • No soot blowers required.
  • Lower velocity in furnace so less erosion.
  • Less super heater erosion.
