Manufacturing portland cement with thermal plasma

Abstract

Various examples are provided related to manufacturing portland cement with thermal plasma. In one example, a method includes providing a raw kiln feed to a plasma arc gasification kiln; and forming clinker by heating the raw kiln feed in the plasma arc gasification kiln. The raw kiln feed can be heated with a plasma plume supplied with argon gas to a temperature in a range from about 1800° C. to about 3000° C. In another example, a system includes a kiln feed system and a plasma arc gasification kiln that receives raw kiln feed from the kiln feed system and heats the raw kiln feed with a plasma plume to form clinker. The system can include a clinker processing system configured to process the formed clinker to produce portland cement.
