  • Method for decreasing sulfuric acid and sulfuric anhydride present in combustion exhaust gas
    Patent number: 6245308
    Abstract: This invention relates to a method for decreasing sulfuric acid and sulfuric anhydride present in combustion exhaust gas which comprises adding an SO3-decreasing agent (hydrogen gas) to combustion exhaust gas and thereby reducing sulfuric acid (H2SO4) and sulfuric anhydride (SO3) present in the combustion exhaust gas, as well as a combustion exhaust gas flow system therefor. Thus, this invention provides a method for decreasing sulfuric acid and sulfuric anhydride present in combustion gas which can prevent the occurrence of troubles (e.g., low-temperature corrosion and ash deposition) arising from H2SO4 and S3 contained in combustion gas.

  • Coal burner combined power plant having a fuel reformer located within the coal furnace
    Patent number: 5704206
    Abstract: A coal burner combined power plant includes a gas turbine for burning coal in a furnace under the pressure and uses produced gas. A steam turbine is combined with an exhaust gas boiler using exhaust gas from the gas turbine. Another fuel is burned at an inlet of the gas turbine for allowing the temperature at the inlet of the gas turbine to rise. A fuel reformer reforms the other fuel and is located within the furnace.
