A case study on shut down audit of AFBC Boiler

10. When a PA line is de-choked, the fire comes in to the fuel cross. The coal smothers inside fuel cross creating a perpetual choking. Hence once the line is de-choked, the smothered coal must be removed at the earliest, by partial draining of the coal from the vertical pipes below the fuel cross.
