  • Publication number: 20170191657
    Abstract: A boiler system for combusting a fuel in the presence of a gas containing oxygen gas, and a gas cleaning system. The boiler system includes a compression device, a carbon dioxide supply duct operative for forwarding at least a portion of the pressurized carbon dioxide rich flue gas to at least one gas cleaning device.

  • Patent number: 9638416
    Abstract: A boiler system (101) comprises a boiler (2) for combusting a fuel in the presence of a gas containing oxygen gas, and a gas cleaning system (106). The boiler system (101) comprises a compression device being operative for pressurizing at least a portion of the carbon dioxide rich flue gas from which at least a portion of the contaminant content has been removed, and a carbon dioxide supply duct (142; 143; 145) being operative for forwarding at least a portion of the pressurized carbon dioxide rich flue gas to at least one gas cleaning device (108; 110; 111) for being utilized as a utility gas therein.

  • Patent number: 9486736
    Abstract: A gas cleaning system (8) for cleaning a carbon dioxide rich flue gas containing sulphur dioxide generated in a boiler (2) comprises a first gas cleaning device (10) being operative for removing at least 80% of the sulphur dioxide content of the flue gas generated in the boiler (2), thereby generating a partly cleaned carbon dioxide rich flue gas, and a second gas cleaning device (12), being separate from the first gas cleaning device (10) and being operative for receiving at least a portion of the partly cleaned carbon dioxide rich flue gas that passed through the first gas cleaning device (10). The second gas cleaning device (12) is operative for removing at least a portion of the water content of the partly cleaned carbon dioxide rich flue gas by means of cooling the partly cleaned carbon dioxide rich flue gas to condense water there from.

  • Publication number: 20130098104
    Abstract: A gas cleaning system is operative for removing water vapour from a carbon dioxide rich flue gas generated in a boiler combusting a fuel in the presence of a gas containing oxygen gas. The gas cleaning system comprises a flue gas condenser (12) being operative for condensing water from at least a portion of the carbon dioxide rich flue gas generated in the boiler by bringing the carbon dioxide rich flue gas into contact with a circulating cooling liquid, thereby generating a cleaned carbon dioxide rich flue gas having a lower concentration of water vapour than the carbon dioxide rich flue gas leaving the boiler. The gas cleaning system comprises a heat pump (100) being operative for absorbing heat at a first temperature from the cooling liquid, and for desorbing heat at a second temperature, being higher than the first temperature, to a heat sink (124).
