Abstract
There is provided a dispersion apparatus for use with a solid fuel burner. The dispersion apparatus comprises a passage through which particulate material may flow toward an outlet region for dispersal therefrom, the flow being at least in part rotational about the longitudinal axis of the passage. The dispersion apparatus also comprises a downstream guide means arranged within the passage at or near the outlet region, the downstream guide means configured to at least reduce the rotational motion so that the flow progresses toward the outlet region in a substantially uniform manner in a direction aligned with a longitudinal axis of the passage.
Claims15
A dispersion apparatus for use in conditioning the flow of a particulate material flowing therethrough, the apparatus comprising:
- a passage through which particulate material may flow from an inlet region toward an outlet region for dispersal therefrom, the flow being at least in part, rotational about a longitudinal axis of the passage;
- a downstream guide arranged within the passage, the downstream guide configured to at least reduce the rotational motion so that the flow progresses from the downstream guide toward the outlet region in a substantially uniform manner in a direction aligned with the longitudinal axis of the passage;
- an upstream guide provided upstream of the downstream guide and configured for introducing into the flow a component of angular or rotational motion for moving the particulate material about the longitudinal axis of the passage;
- wherein the upstream guide comprises more than one spiral, the spirals arranged within the passage and configured so as to extend along the passage from the inlet region to the downstream guide;
- and
- wherein the inlet region comprises a manifold arrangement which serves to direct the particulate material into an upstream region of the passage, wherein the manifold arrangement is configured to divide incoming particulate material into a number of streams of flow, such that each stream of flow is directed toward a respective spiral.
A method for modifying the path of travel of particulate material flowing through a passage of a dispersion apparatus or dispersion lance from which the particulate material is to be dispersed from, the method comprising:
- introducing into the flow of particulate material at an inlet region of the passage upstream and proximal of an outlet region, a component of angular or rotational motion for moving the particulate material about the longitudinal axis of the passage by providing more than one spiral within the passage, the spiral configured to extend along the passage from the inlet region to a downstream guide;
- directing the particulate material into an upstream region of the passage with a manifold arrangement, wherein the manifold arrangement divides the particulate material into a number of streams of flow, such that each stream of flow is directed toward a respective spiral;
- and
- modifying the path of flow of the particulate material using the downstream guide of the dispersion apparatus or dispersion lance to at least reduce any rotational motion of the flow about a longitudinal axis of the passage so that the flow progresses from the downstream guide toward the outlet region in a substantially uniform manner in a direction aligned with the longitudinal axis of the passage.
