Carbon dioxide production

摘要

An apparatus for the production of carbon dioxide from limestone is disclosed which includes a nuclear energy source 32 arranged to generate electricity and a rotary kiln 10. The rotary kiln 10 has an inlet 15 for the introduction of limestone and an outlet 19 for the release of carbon dioxide. An electrical resistance heating element 21 disposed within the kiln 10 is arranged to be supplied with electricity derived from the nuclear energy source 32 to raise the temperature of the element 21 for transfer of heat to the interior of the rotary kiln 10. Limestone in the rotary kiln 10 is thereby heated to a temperature sufficient for the release of carbon dioxide.
