... with higher amounts of high specific gravity particles, in the size ranges characteristic of bottom ash, were found to produce more bottom ash, indicating the potential utility of float sink methods in the prediction of bottom ash removal requirements. 20 06 2005 22 08 2006 fly ash...

... sludge, ranging between 40% and 80%. It is believed that in this latter case, a slightly higher temperature could have enhanced the volatilization, especially of Cd and Pb. However these metals were then retained in fly ashes captured in the cyclones. In the case of Hg, the volatilisation was complete...

... on the carbon content in fly ash, distribution of oxygen in the furnace, distribution of temperature in the furnace, distribution of bed pressure, and operation under low load. Some methods used to improve the CFB boiler operation are discussed in the paper. Contributed by the Fuels and Combustion...
