Abstract
A process for hydrating CaO residues in fluidized bed combustor ashes that achieves a better level of hydration, which does not add significantly to the cost of the hydration process, which reduces the consumption of water in the hydration process, and which if desired can trap at least some of the CO,in the furnace gasses, by using some of it to convert the hydrated CaO to CaCO,. This both reduces the amount of CO,released to the atmosphere, and converts the potentially dangerous CaO in the ashes into an effectively inert and benign material. By exposing the ash/water mixture to sound under the correct conditions of frequency, and power input, it is possible to improve both the rate of hydration, and the level of hydration, of FBC ashes. The process can be carried out either batchwise or continuously, and does not require an extended time period.
