Abstract
Exemplary arrangements relate to a method for incinerating waste on a combustion grate of a furnace and an apparatus for carrying out such a method. Oxygen mixed with carrier gas is supplied to the combustion for incineration as an oxygen and carrier gas mixture. The carrier gas comprises recirculated combustion gas from the furnace and may have a CO2 concentration of from 10% to 99%.
Claims20
A method comprising:
- a) incinerating waste supported on a combustion grate of a furnace via combustion,
- b) during at least a portion of (a), adding an oxygen and carrier gas mixture to the combustion,
- wherein the carrier gas comprises recirculated combustion gas produced by the combustion within the furnace with a CO2 concentration of from 10% to 99%.
A method comprising:
- a) carrying out combustion within an interior area of a furnace to incinerate waste,
- b) during at least a portion of (a) adding a mixture comprised of oxygen and carrier gas to the interior area of the furnace, wherein the carrier gas comprises recirculated combustion gas produced by the combustion within furnace with a CO2 concentration of from 10% to 99%.
Apparatus comprising:
- a furnace,
- wherein the furnace includes an internal combustion grate,
- wherein the furnace is configured to incinerate waste supported on the combustion grate via combustion in a combustion zone,
- a separating device,
- wherein the separating device is operative to
- receive combustion gas produced by the furnace during combustion, and
- separate CO2 from the combustion gas produced by the furnace,
- at least one conduit operative to deliver a mixture of oxygen and the CO2 separated from the combustion gas into the combustion zone.
