Abstract
A system for combusting carbon-containing fuel includes a reactor 10 for simultaneously supporting oxidation of the fuel and conversion of CO2 within the reactor. A metal oxide or metal is input to the reactor to convert the CO2 to a mineralized CO2 product. A cold trap 44 is provided for capturing exhaust gases from the reactor and returning condensate to the reactor, and a gas pump 50 maintains a desired vacuum or pressure within the reactor and the cold trap. Combustion products may be recycled to increase their energy value.
Claims29
A system for combusting a carbon-containing fuel, comprising:
- a reactor for supporting simultaneous oxidation of the fuel and conversion of CO2 therein;
- a metal oxide or metal for inputting to the reactor to convert the CO2 to a mineralized CO2 solid product;
- an exchanger downstream from the reactor for transferring heat from the mineralized CO2 solid product;
- a separation unit for capturing condensable vapors in exhaust gas from the reactor;
- and
- a gas pump for maintaining a desired pressure within the reactor.
A method of generating heat from a fuel, comprising:
- supporting simultaneous oxidation of the fuel and conversion of CO2 in a reaction chamber of a reactor;
- inputting a metal oxide or a metal to the reactor to convert the CO2 to a solid metal carbonate product;
- capturing exhaust gas from the reactor;
- and
- maintaining a desired pressure within the reactor.
