Abstract

The cohesive zone plays very important role in the operation of COREX melter gasifier. A two-dimensional 1/30 scale thermal dynamic model, in which paraffin and corn are used to simulate DRI, coke and lump coal respectively, has been established to study the cohesive zone of COREX melter gasifier. A set of different operation parameters, such as discharging rate (melting rate), DRI to lump coal and coke volume ratio, blast temperature as well as blast volume, were taken into account. The effects of these mentioned parameters on cohesive zone position and thickness in COREX melter gasifier have been analyzed in detail.
