Thesis Abstract

This research is centered on the design and fabrication of copula furnace and atomizer for the production aluminium powder metal with the available material.0.4kg of refined coke was chosen as the basis for material and energy balance calculations and the design calculations performed from whose values are used to produce the design drawings. Mild steel was used for the internal linings of the furnace casing while other material were selected based on functionality, durability ,cost and local availability. The furnace and atomizer were assembled and the furnace inner wall of the casing was lined with refractory bricks made from heated mixture of kaolin, clay, sawdust and water after which the cylindrical shell was positioned. Testing was subsequently performed to evaluate the performance of the furnace and the atomizer by first gathering of the aluminum cans. The furnace was heated to 8700c and it was observe that the furnace has 36.9% efficiency which is within the acceptable value for furnace efficiencies. Atomizer produced various sizes of powder metal depending on the type of mesh used and the shape obtained  was irregular in shape.
