    201665 · Abstract. Circulating Fluidized Bed (CFB) technology has emerged as the most favoured steam generation technology in recent times. The use of CFB boilers is growing exponentially due to its attractive features such as fuel flexibility stable operation and low acid gas emissions to name a few. The design of CFB boilers has developed over the
