ABSTRACT:
The present invention relates to the wetting or providing moisture throughout a container of a powdery dry material such as an emission control baghouse dust. A collection hopper container is provided which usually comprises a box like structure with a sealable cover or top. A supply of low-pressure steam is provided to a plurality of conduits that extent through the cover and extend downwardly into the collected powdery material. By the injection of low-pressure steam through the plurality of conduits and outwardly into the powdery material through openings in the conduits, moisture is provided throughout the powdery material to lessen the dusty nature of the material to enable further processing to be accomplished more readily.
