Abstract
A system and method of combusting aluminium comprising i) feeding aluminium wire to a substantially oxygen-free furnace comprising a. a first low-temperature section in communication with b. a second high-temperature section ii) forming aluminium particles with an average particle size ranging from 1 μm to 200 μm from said aluminium wire in said first section iii) feeding water and/or steam to said first and/or second section to provide an oxidizer for oxidizing said aluminium particles in the second section iv) conveying aluminium particles from the first section to the second section v) oxidizing said aluminium particles in the presence of steam in said second section.

A method of combusting aluminium, the method comprises:
- i) feeding aluminium wire to a substantially oxygen-free furnace comprising:
- a. a first low-temperature section in communication with
- b. a second high-temperature section
- ii) forming aluminium particles with an average particle size ranging from 1 μm to 200 μm from said aluminium wire in said first section;
- iii) feeding water and/or steam to said first and/or second section to provide an oxidizer for oxidizing said aluminium particles in the second section;
- iv) conveying aluminium particles from the first section to the second section;
- and
- v) oxidizing said aluminium particles in the presence of steam in said second section, wherein the aluminium wire has a cross sectional area ranging from 0.1 to 50 mm2.
