摘要

Combustion products resulting from the combustion of gaseous fuels (19) containing hydrogen as an exit from the heat source (2) in thermo capacitor (1) cooled to a temperature that is below the dew point of flue gas and is lower than the temperature of the return branch (4) heating medium, the cooling occurs condensation of water vapor and dry gas. Combustion products may cool to below the liquefaction temperature of CO2 from the flue gas CO2 into the atmosphere. Heat from the thermo capacitor (1) can divert the heat pump (9), its output heats the heating medium, preferably in the return line (4). At least part of the heat source (2) may take the form of a cogeneration unit (8), generating electricity, at least a portion of electricity generated is then used to drive the heat pump (9). Flue gas after leaving the thermo capacitor (1) can be heated in the second heat exchanger (11). The flue is connected the thermo capacitor (1) as heat source for heat pump (9) and / or separator (6) CO2.
