Pure oxygen direct combustion system using liquid metal

A pure oxygen direct combustion system using a liquid metal, the pure oxygen direct combustion system comprising:

• a reactor in which a liquid metal is fulfilled;
• a first heat exchanger connected to a lower portion of the reactor such that heat is exchanged between the liquid metal and the heat exchanger;
• a circulation pump connected to the first heat exchanger to circulate the liquid metal;
• and
• a buffer tank connected to the circulation pump and situated on an upper surface of the reactor,
• a reduction unit connected to the circulation pump to perform a reduction operation on an oxidized liquid metal;
• and
• a separation unit connected to the reactor and the reduction unit,
• wherein particles of the liquid metal supplied from the buffer tank is resupplied to the reactor after receiving sensible heat from a gas generated in the reactor and being reproduced through the reduction unit;
• and
• wherein particles of the liquid metal supplied from the buffer tank are resupplied to the reactor after receiving sensible heat from a gas generated in the reactor and passing through the first heat exchanger.
