<p>PURPOSE:To reduce energy consumption by supplying the steam extracted from the low pressure part of a steam turbine to the reboiler of a CO2 absorbing solution regeneration tower as a heating source and supplying the condensed water generated in the reboiler to a boiler. CONSTITUTION:CO2 in combustion exhaust gas generating steam for driving a steam turbine 3 is absorbed and removed by a CO2 absorbing solution and the CO2 absorbing solution having CO2 absorbed thereinto is supplied to a CO2 absorbing solution regeneration tower 24 having a reboiler 30 and an overhead condenser 25 to be regenerated. At this time, the steam extracted from the low pressure part 7 of the steam turbine 3 is supplied to the reboiler 30 of the CO2 absorbing solution regeneration tower 24 as a heating source and the condensed water generated in the reboiler 3 is supplied to a boiler 1. That is, when CO2 in the combustion exhaust gas generating steam for driving the steam turbine is absorbed and removed by the CO2 absorbing solution to be recovered and the CO2 absorbing solution is regenerated to be reutilized, and resultantly energy consumption can be reduced.</p> |
