ABSTRACT:
An apparatus for conveying particulate material that is directed through an outlet passage (50) of a chamber (40). The apparatus includes a slurry-conveying conduit (54) communicating with the outlet passage and further including liquid flow control means (58, 68, 70 and 59) for only partially filling the conduit with a liquid for conveying the particulate material away from the chamber as a slurry while maintaining an air passage (72) in the conduit that communicates with the outlet passage of the chamber; and vacuum creating means (74, 77) communicating with the air passage in the conduit for establishing a partial vacuum in the passage to impede liquid vapors from flowing into the chamber. The method in which the above apparatus is operated also forms a part of the present invention.
