POWER GENERATING DEVICE WITH CARBON DIOXIDE GAS RECOVERY DEVICE AND POWER GENERATING METHOD

摘要

PURPOSE:To improve efficiency of power generation without reducing power generating output even when demand of electric power is increased in the daytime by storing into a storing facility, carbon dioxide gas absorbing liquid which absorbed produced carbon dioxide gas by means of an absorbing device and regenerating carbon dioxide gas absorbing liquid stored in the storing facility, and then storing it into a storing facility for absorbing carbon dioxide gas. CONSTITUTION:Steam generated in a boiler 1 is led into a turbine power generator 2 by a line 3 so as to generate power. A tank 15 is provided as a storing facility for carbon dioxide gas absorbing liquid in which carbon dioxide gas is absorbed. A tank 16 is provided as a storing facility for regenerated carbon dioxide gas absorbing liquid. An absorbing column 7 is operated by day and by night during power generation so as to absorb carbon dioxide gas, and on the other hand, carbon dioxide gas absorbing liquid is not regenerated at the time of shortage of electric current. Carbon dioxide gas absorbing liquid including carbon dioxide gas generated in the absorbing column 7 is stored into the tank 15 in daytime, and a regenerating column 10 is operated in night so as to regenerate carbon dioxide gas absorbing liquid.
