Abstract

1321715 Fluidised bed NATIONAL RESEARCH DEVELOPMENT CORP 28 July 1971 [14 May 1970] 23429/70 Heading B1F A baffle 4, Figs. 1 and 2, for redistributing gas bubbles flowing through the fluidised bed in reactor 1 has upwardly tapering passages and downwardly tapering passages formed by conical passages 6. In Fig. 3 two nets of conical passages overlap in a vertical direction to form the baffle.
