    Abstract: In an exhaust gas treatment system including a denitration device that removes nitrogen oxide in exhaust gas from a heavy fuel-fired boiler, an air preheater that recovers heat in the gas after the nitrogen oxide is removed, an electric precipitator that removes dust while adding ammonia into the gas after heat recovery, a desulfurization device that removes sulfur oxide in the gas after dust removal, and a stack that exhausts the gas after desulfurization to the outside, an ash-shear-force measuring instrument is provided to measure an ash shear force, which is ash flowability, on the downstream side of the electric precipitator, so that a feed rate of an air supply unit that supplies air to the boiler is reduced according to ash shear-force information.

    Abstract: 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.
