Abstract

Aluminium hydroxide is dried and de-hydrated it is transferred to a heating chamber, heated and discharged. The speed of alumina in the fluidised bed in the discharge region and in the feed region of the heating chamber is in the ratio 10:40. The proposed equipment comprises a vertical, cylindrical heat exchanger for de-hydration. A heating chamber arranged co-axially with and connected by pipework to it. A grid separates the heat exchanger into upper and lower zones. Material for fluidisation is introduced into the lower zone through the pipe connection. The space above the grid is equipped with a fuel firing unit. The pipe connection and the heating chamber share a common wall, which is provided with a vertical slot and through openings. The vertical slot is located above the fluidised bed, while at least one through opening is located at the level of the fluidised bed.
