Abstract

Agglomeration of ash is a major issue in fluidized bed combustion boiler, large agglomeration decreases the bed mixing and result of this activity de-fluidisation take place in the boiler. This cause a shutdown of the combustor because of defluidization. In recent years, significant advances have been made in understanding and predicting the behavior of ash in combustion and gasification systems. In CFBC boilers ash sintering may contribute to deposit formation in the cyclone, return leg and post cyclone flue gas channel. Rapid sintering can lead to heavy agglomerate formation, which may finally inhibit circulation in dense phase areas (such as seal pot and return leg). Hence understanding the sintering behavior before the fuel is used, would be desirable for avoiding problems. A survey of ash agglomeration and deposit formation in industrial boiler found that all the boiler facing some form of bed ash agglomeration. In combustion using Indian coal having high percentage of sulphur ash becomes deposited on the bed particles. After certain temperature (about 800OC to 1000OC) ash showing the sticky behaviour tend to stick ash and form agglomerates. In this study we are trying to find out that what is the causes of this ash agglomeration ? How the agglomeration problem analyzed by different researcher. Which solution or method provide by researcher to reduce ash agglomeration or eliminated from the affect area of fluidized bed boiler.
