One way to reduce the problem of bed agglomeration is to increase the removal rate of bed material and the addition rate of makeup material. This reduces the amount of alkali material available in the bed for the formation of a sticky coat on the bed particles. A better way is to change the bed material to a less troublesome one if such a material can be identified. The main trend these days seems to be that fluid …

· PDF fileTo increase the knowledge about how to reduce alkali-related problems in circulating fluidized bed (CFB) boilers, several tests with ammonium sulfate injections have been performed [7, 9]. In this work, bed agglomeration was investigated when co-firing different biomass fuels
04-05-2010· In grate-fired boilers this reduces the amount of fine fuel particles lifted off the grate and thus the amount of carryover of unburned material from the furnace. In BFB boilers less primary air means a lower bed temperature, meaning lower risk of bed agglomeration.
