22. With the exception of mercury, heavy metals are emitted in solid form in association with fly-ash particles. Different coal combustion technologies show different magnitudes of fly-ash generation: grate-firing boilers 20–40%; fluidized-bed combustion 15%; dry bottom boilers (pulverized coal combustion) 70–100% of total ash. The heavy metal content in the small particle size fraction of the fly-ash has been found to be higher.
