Abstract
The invention pertains to a vessel () for storing particulate matter, such a pulverized coal or fly ash, comprising a main part () and, at its bottom portion, at least one discharge device (), which comprises a converging outer shell () and a permeable, converging inner shell () positioned in the outer shell (), the discharge device () being connected to the main part () by means of a first flange () at or near the lower rim of the bottom portion of the main port () and a second flange () at or near the upper rim of the outer shell (). The inner shell () is secured to the inner wall of the outer shell () of the discharge device (), preferably to the inner wall of the second flange (). Thus the number of gaskets is reduced an/or the positioning of the inner shell becomes less critical.
