Apparatus and process for calcining feed material

A calcination system comprising:

• a calciner having an outlet in communication with a chamber;
• at least one burner connected to the calciner to form at least one flame within the chamber for calcination at a pre-selected calcination temperature range of between 815° C. and 2,205° C.;
• at least one filter device connected to the outlet of the calciner to receive calcined material entrained within combustion gas from the calciner to separate the calcined material from the combustion gas;
• and
• a carbon capture system connected to the at least one filter device to receive the combustion gas for removal of moisture from the combustion gas and capturing of carbon dioxide from the combustion gas;
• and
• wherein a source of solid particulate feed material is connectable to the at least one burner and/or the calciner to feed the solid particulate feed material into the at least one flame for a first phase of calcination of the solid particulate feed material, the calciner sized and configured so that the solid particulate feed material passes from the flame to the outlet within the chamber of the calciner for a second phase of calcination of the feed material so that a pre-selected residence time of the solid particulate feed material for calcination to form the calcined material is greater than 5 seconds and is less than or equal to 5 minutes.
