BPI air pollution control (APC)
systems typically consist of a dry sorbent injection system with a
fabric filter (DSI/FF). Dry sorbent is injected into the cooler
combustion gases leaving the boiler economizer. The sorbent,
typically dry lime, provides for the removal of a large portion of
the acid gases (SO2 and HCl). Powdered activated carbon (PAC) is
also injected at this point to remove heavy metals and
dioxins/furans. The gases then pass through a fabric filter, which
removes in excess of 99.99% of all particulates. The clean gas
exiting the fabric filter is discharged to the stack, where the
gases are then emitted at an elevated point in the atmosphere. Fly
ash collected in the boiler and fabric filter hoppers is transported
by conveyor to the main ash discharge conveyor.
BPI’s air pollution control systems have realized superior results. |
