摘要： A dust collecting apparatus and method for dedusting a Ca-containing gas using a ceramics filter is provided, in which a filter differential pressure elevation rate is suppressed. A desulferizing agent 103 and a mineral 106 containing MgO are supplied via a hopper 13, 15 a valve 14 and a feeder 16 into a pressurized fluidized-bed combustion furnace 1 together with coal 101 and air 102. A combustion gas 201 is dedusted by a cyclone 2 to become a combustion gas 301, the combustion gas 301 enters a filter container 3a, 3b having a ceramics filter 31a, 31b and is further dedusted. A combustion gas 401 which is dedusted is supplied into a gas turbine 4 to generate power, and combustion gas 501 heats a waste heat recovery boiler 5 which in turn drives a steam turbine 7. The mineral 106 containing MgO is added in the combustion gas 301 which flows in the ceramics filter 31a, 31b. Thereby MgO is added to the combustion gas so that the filter differential pressure elevation rate can be suppressed. The more MgO that is supplied, the greater the effect becomes, and an operation stop due to the differential pressure elevation is eliminated.

摘要： Fuel, desulfurizing agent and air are fed into a fluidized bed gasification furnace so that part of the fuel is gasified. The produced combustible gas is led into a combustor. Residual fuel not gasified within the fluidized bed gasification furnace is led to a fluidized bed combustion furnace jointly with the desulfurizing agent to burn it with air fed separately to the combustion furnace. Then produced combustion gas is led into the combustor, in which the combustible gas is burnt with the combustion gas and air fed seperately to the combustor. The amounts of air fed to the respective furnaces and the combustor are individually regulated. A gasifying power generation method includes, in addition to the abovementioned steps of the gasifying combustion method, the steps of driving a gas turbine by the combustion gas produced by the combustor, driving a steam turbine by steam generated by the combustion gas, and rotating electric generators by the respective turbines to carry out power generation.

摘要： A CO.sub.2 deep sea throw-away system includes a floating offshore base (2), receiving liquefied CO.sub.2 carried by a liquefied CO.sub.2 carrier (1). The base has a throwing pipe (3) and a throwing pipe outlet (4) to deliver the liquified CO.sub.2 in an enclosing bag (11) in the sea at a depth where a liquid phase state of the liquified CO is maintained. An unmanned submersible working boat (10) is provided and has a plurality of capsules (26) mounted thereon. Each capsule contains an enclosing bag (11) to enclose the liquified CO.sub.2. The boat transports the capsules into the sea at a depth where a liquid phase state of the liquified CO.sub.2 is maintained and operates to enclose the liquified CO.sub.2 in the enclosing bags (11). The liquified CO.sub.2 in the enclosing bag (11) and the capsule (26) are then released so as to fall onto the sea bottom. Also, a control base (9) is provided on the offshore sea to control the unmanned submersible working boat (10).

摘要： 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.
