Un aparato de transporte para transportar un material particulado desde una fuente a un quemador provisto en un horno flash, comprende un medio de transporte neumático para transportar el material particulado a una velocidad relativamente alta, y un dispositivo para modificar el flujo provisto en o cerca de la entrada del horno.

摘要

A pneumatic conveyor flow modifier 121a receives and arrests a relatively high velocity stream of powdered material, and outlets the material at a relatively low velocity, such as via its internal geometry. For example, an arresting wall 42 at right angles to the direction of flow, with a relatively large outlet one adjacent the wall. The flow modifier 121 a, which may come in a variety of shapes, controls and optimises the flow of powdered material to be burnt in flash furnace.
