Beschreibung
Zusammenfassung:	FIELD: power industry. ^ SUBSTANCE: method of furnace gas treatment consists in combustion of part of furnace gas from the gas turbine in the boiler that is bled at the input to waste-heat boiler or output of waste-heat boiler for increasing of carbon dioxide concentration in furnace gas and extraction of carbon dioxide in carbon dioxide extraction device; at that waste-heat boiler is performed with the possibility of heat recovery of high-temperature furnace gas. The boiler is performed with the possibility of high-pressure steam generation that is required for carbon dioxide extraction and compression. The device for furnace gas treatment contains gas turbine, boiler for combustion of furnace gas from gas turbine and device for carbon dioxide extraction performed with the possibility of carbon dioxide extraction after increase of its concentration in the furnace gas from the boiler. Note that the boiler is performed with the possibility of high-pressure steam generation that is required for carbon dioxide extraction and compression. ^ EFFECT: invention helps to increase efficiency of carbon dioxide treatment that is contained in furnace gas. ^ 6 cl, 12 dwg Изобретение относится к области теплоэнергетики. Способ обработки топочного газа заключается в сжигании в котле части топочного газа из газовой турбины, отбираемого на входе в котел-утилизатор или на выходе из котла-утилизатора, для увеличения концентрации диоксида углерода в топочном газе и извлечении диоксида углерода в устройстве извлечения диоксида углерода, при этом котел-утилизатор выполнен с возможностью рекуперации тепла высокотемпературного топочного газа, а котел выполнен с возможностью генерации пара высокого давления, требуемого для извлечения и сжатия диоксида углерода; устройство обработки топочного газа содержит газовую турбину, котел для сжигания топочного газа из газовой турбины и устройство извлечения диоксида углерода, выполненное с возможностью извлечения диоксида углерода после увеличения его концентрации в выходящем из котла топочном газе, причем котел выполнен с возможностью генерации пара высокого давления, требуемого для извлечения и сжатия диоксида углерода. Изобретение позволяет повысить эффективность обработки диоксида углерода, содержащегося в топочном газе. 2 н. и 4 з.п. формулы, 12 ил.
