move freely, giving the bed a liquid-like (fluidised) characteristic. CFBC technology offers several benefits. CFBC boilers are extremely flexible, allowing a wide range of fuel qualities and sizes to be burnt. Emissions of SOx and NOx are significantly reduced without the addition of expensive flue gas emissions control systems.

Circulating Fluidized Bed Boiler Design and operation and Maintenance by Prabir Basu. This book is designed to provide practicing engineers, students, and researchers with insights into the operation and principle of the working of circulating fluidized bed (CFB) boilers.
In fluidized-bed boilers a bed, usually consisting of sand particles, is brought into a fluidized state by primary air supplied from below the bed. Solid fuel added to the bed will burn in the oxygen-rich conditions inside the bed created by the primary air.
Most of the circulating, atmospheric-pressure fluidized-bed boiler (CFBC) technologies were introduced into Japan from abroad, beginning around 1986. 5. Progress and development results ˜ CFBC technology was introduced from abroad and used in coal-fired boilers. It is used by power producers, iron makers, paper producers, and in other sectors.
Circulating fluidized bed is a relatively new technology with the ability to achieve lower emission of pollutants. Extensive research has been conducted on this technology for the past 10 years because pollution in the world is getting more serious by the day and clean practice will be very crucial for the sustainability of the earth.
Dec 24, 2018 · Atmospheric Fluidized bed boilers are most common and simple FBC boiler where combustion takes place at layer of sand or sand like material. Bubbling of sand bed is created with the help of fluidizing air of velocity 1.2-3.7 m/sec. Coal of size 0-10mmis spread over bed (typically 1-6 mm size for under bed firing and 6-10mm for overbed firing), as soon as it reaches bed combustion takes place. In bed tubes are used in AFBC boiler for maximizing heat transfer.

Circulating fluidized bed combustion (CFBC) is an inno- vative technology for coal burnin g that can achieve in situ SO 2 removal by injecting calcium-based absorbent into the com- bustor.
CFBC boilers do not have bed coils as in AFBC. The steam is generated across the entire furnace. The heat transfer coefficient is dependent on the amount of fines present in the recirculating ash. The following are the possible causes for loss of steam generation.
