1 - 12 . (canceled)
13 . A method for cooling flue gas from a combustion boiler within a building, the method comprising providing the flue gas to at least one economizer having at least one set of cooling coils conveying the boiler feed water, the providing cooling the flue gas and heating the boiler feed water.
14 . The method of claim 13 further comprising providing the heated boiler feed water to the combustion boiler.
15 . The method of claim 13 further comprising, after providing the flue gas to the one set of coils, providing the flue gas to another set of coils conveying potable or industrial process water, the providing further cooling the flue gas and heating the potable or industrial process water.
16 . The method of claim 15 further comprising providing the heated potable or industrial process water to a water heating system.
17 . The method of claim 16 further comprising heating the water heating system with steam from the combustion boiler.
18 . The method of claim 15 wherein the one set of cooling coils is a component of one economizer and the other set of cooling coils is a component of another economizer.
19 . The method of claim 18 wherein the one economizer is a non-condensing economizer, and the other economizer is a condensing economizer.
20 . The method of claim 18 further comprising, after providing the flue gas to the one economizer, providing the cooled flue gas through a diverter to divert at least some of the cooled flue gas to the other economizer.
21 . The method of claim 20 further comprising providing the cooled flue gas from the diverter to the other economizer with a blower.
22 . The method of claim 13 wherein the flue gas is at least about 10% carbon dioxide prior to entering the one economizer.
23 . The method of claim 13 wherein the flue gas is about 3% free oxygen prior to entering the one economizer.
24 . The method of claim 13 further comprising liquefying carbon dioxide after cooling the flue gas.
