Gas-solid flow occurs in many industrial furnace processes. The majority of chemical engineering unit operations, such as drying, separation, adsorption, pneumatic conveying, fluidization and filtration involve gas-solid flow.Poor powder handling in an industrial furnace operation may result in a bad furnace performance, causing errors in the mass balance, erosion caused by particles impacts in the pipelines, attrition and elutriation of fines, overloading the bag houses. The lack of a good gas-solid flow rate measurement can cause economic and environmental problems due to airborne dust. The paper is focused on the applications of powder handling in relation with furnaces of the aluminum smelter processes such as anode baking furnace and electrolytic furnace (pot cell) to produce primary aluminum.
