We are facing the global warming. The main green house effect gas is carbon dioxide from fossil power generating stations. In addition, in the event of the nuclear power station accident, we must burn more natural gas and coal instead of nuclear energy. A lot of carbon dioxide will be exhausted. Using the chemical absorption or the oxygen and coal fired furnace, the studies to recover CO_2 of flue gas of coal-fired power stations and to separate recovered CO_2 under deep land (Carbon Capture and Separation/CCS) have been developed. But it will be difficult to achieve CCS economically. In order to achieve economical CCS, it will be necessary to develop the new power generating system. Last year, the author proposed the modified oxygen-blow rankine-cycle turbine (MORIT). Fuel is combusted with oxygen. Heat exchanges from the exhaust gas and high concentration CO_2 will be gained. The heat and mass balance calculation with biomass derived fuel (BDF) secondary product (glycerol). In this paper, using natural gas as fuel, the author calculate the heat and mass balance changing main steam pressure 66-125 kg/cm^2.
