摘要： PROBLEM TO BE SOLVED: To prevent the re-release of Hg after desulfurization by preventing the increase in the Hg concentration on the solid side in the circulation tank of a flue gas desulfurization apparatus.SOLUTION: It has been ascertained that a low-gypsum concentration underflow 44-side liquid left after a sulfur oxide absorbent solution is extracted from the absorbent solution reservoir of a desulfurizer 3 and part of the gypsum is separated and removed by means of a first solid/liquid separator 38 is recycled as makeup water for the desulfurizer 3, the overflow 43-side liquid from the first solid/liquid separator 38 contains a high concentration of small-particle-diameter Hg. Accordingly, the underflow 44-side liquid obtained by passing the underflow 44-side liquid through a filter 40 for solid/liquid separation and the overflow 43-side liquid are combined together in a circulating water tank 41 to form recirculation water, and a coagulant is added to the recirculation water to effect the coagulation and particle size growth of high-Hg concentration fine particles recirculated into the desulfurizer 3 to thereby make it possible to efficiently perform solid/liquid separation in an absorbent solution solid/liquid separator 54 located downstream of the position of coagulant addition.

摘要： PROBLEM TO BE SOLVED: To provide a wet two step flue gas desulfurization apparatus maintaining high performance of removing/absorbing dust or trace constituents in exhaust gas and preventing increase of a mist scattering amount scattered to a desulfurization/absorption tower at a rear flow side of a Venturi scrubber during low load operation of a boiler. SOLUTION: The wet two step flue gas desulfurization apparatus is made to have the Venturi scrubber 1 having a throat part 5 for absorbing, removing, and collecting the dust in the exhaust gas and a mist eliminator 8 for removing mist containing the dust collected by the throat part 5 at the upper stream side of the exhaust gas passage of the desulfurization/absorption tower 2 for absorbing the sulfur oxide in the exhaust gas discharged from a combustion device. A plurality of the Venturi scrubbers 1 are installed in parallel and the number of the Venturi scrubbers 1 for introducing the exhaust gas is reduced when the operation load of the combustion device is decreased than that under predetermined load. Since the plurality of the Venturi scrubbers 1 are installed in parallel and the number of them is reduced under low load, the high gas flow speed at the throat part 5 is maintained even under low load and high performance of removing/absorbing the dust is maintained.

SOLUTION: If voltage reduction of a fuel cell is voltage reduction of the cell (S3) as a whole, when a physical quantity correlated to an anode gas flow rate is less than a set value (S4), the voltage reduction of the fuel cell is determined to be caused by the lack of the amount of hydrogen (S5), when the physical quantity correlated to the anode gas flow rate is larger than the set value (S4); and when the anode gas temperature is lower than the set value, it is determined to be caused by the lack of humidification of reformed gas (S8, S9), when the anode gas temperature is higher than the set value, it is determined to be caused by CO poisoning (S8, S12). In any of the cases, the load current of the fuel cell is reduced (S6-S13) and a command for increasing the amount of hydrogen of the reformed gas corresponding to each cause (S7), a command for raising the anode gas temperature (S11) or a command for reducing the CO concentration of the reformed gas (S14) is outputted.
