| 摘要 |
The present invention relates generally to the cleaning of a flue gas and, in one embodiment, to a device, system and method that mitigates and/or prevents slurry deposition at the flue inlet to a wet flue gas desulfurization (WFGD) unit in order to keep the inlet dry and minimize deposition {e.g., deposition scale) at the flue inlet to the WFGD tower. In one embodiment, a wet flue gas desulfurization (WFGD) unit, system and/or method according to the present invention comprises, among other features, a scale prevention system comprising a plenum air device and/or forced-air box located proximate the inlet transition zone. In another embodiment, a wet flue gas desulfurization (WFGD) unit, system and/or method according to the present invention comprises, among other features, a scale prevention system comprising at least one chill plate located proximate the inlet transition zone. |
