Abstract
The present invention relates to an apparatus for the continuous reduction of sulphur-dioxide containing gases essentially free of molecular oxygen using coal or carbon. The apparatus comprises: a reactor filled with a reducing agent of coal or carbon having an upper portion, at least one middle portion and a lower portion, an outer reactor mantle and inner heat exchange regions; a pipe in the upper reactor portion for introducing pre-heated sulphur dioxide containing gases; spaced apart pipes for introducing hot gases into the outer reactor mantle and into the inner heat exchange regions; device(s) for controlling the hot gas flow in the reactor mantle and in the heat exchange regions so that the temperature in the reactor increases in each portion from the upper portion to the lower portion; and an outlet pipe arranged within the reactor for the reduced sulphur-containing gases.
