Abstract
An apparatus and process for directing particulate material (22) into a moving gas stream includes a delivering of the particulate material (22) from a particulate reservoir (24) along a delivery direction (118) into a housing (30) having a housing axis (32). A housing gas flow is introduced into the housing (30) through at least one entry gas port (40) that has been provided in the housing (30). The housing gas flow is arranged to combine with the particulate material (22) that is delivered from the particulate reservoir (24). A swirling motion is imparted to the housing gas flow, and the swirling motion has at least a rotational component (110) of movement which is directed substantially circumferentially about the housing axis (32).
