摘要： PROBLEM TO BE SOLVED: To remove SO
3 in an exhaust gas without causing a significant increase in the operation cost.
SOLUTION: The concentration of SO
3 in the exhaust gas is reduced by providing a sodium carbonate supplying device 20 for supplying sodium carbonate to the exhaust gas at the outlet of a boiler 1, and a SO
3 -separating device 10 is provided for separating and removing the SO
3 component from the exhaust gas at the inlet of a wet type desulfurization device 7. In the SO
3 separating device 10, a shell and tube type heat exchanger is provided, and the exhaust gas and water to be supplied to the boiler are passed through the shell side and the tube side, respectively, so as to cool the temperature of the exhaust gas to a temperature lower than the dew point of gaseous H
2 SO
4 . With the lowering of the temperature of the exhaust gas, the SO
3 component in the exhaust gas reacts with moisture in the exhaust gas and forms the gaseous H
2 SO
4 , and further, the formed H
2 SO
4 gas condenses and sticks on the surface of the tube. The SO
3 component can be removed from the exhaust gas by washing liquid H
2 SO
4 stuck on the tube with water. Thereby, the consumption of sodium carbonate is markedly reduced and the increase in the cost for operating a plant is prevented.

摘要： PROBLEM TO BE SOLVED: To make it unnecessary to install a fluidized bed heat exchanger in a seal pot into which fluidized material separated from combustion gas is guided by providing a circulating pipe for part of the combustion gas which has been discharged from a furnace and passed through a group of heat transfer pipes to return to the furnace. SOLUTION: Fuel and air are supplied to a bottom portion of a furnace 1 and are mixed with fluidized material supplied from a seal pot 3 to effect combustion. The fluidized material discharged together with combustion gas from the furnace 1 is separated from the combustion gas in a cyclone 2 before being returned to the furnace 1 via the seal pot 3. The exhaust combustion gas is utilized to produce superheated vapor in a group of the heat transfer pipes 4 before being discharged. Part of the combustion gas temperature of which has been lowered by being allowed to pass through the group of the heat transfer pipes 4 is guided into the furnace 1 through a circulating pipe 5 to be injected into air. By introducing the part of exhaust gas passing through the group of the heat transfer pipes 4 and having a temperature of 100 to 200 deg.C into the furnace 1 through the circulating pipe 5, temperature within the furnace 1 can be controlled at around 800 deg.C without installing a fluidized bed heat exchanger in the seal pot 3.

摘要： PROBLEM TO BE SOLVED: To prevent the lowing of the dust collecting capacity by the passing- through of dust, in an apparatus wherein a plurality of dust collecting units are arranged up and down as well as left and right, by setting the heights of the units to two kinds and differentiating the heights of upstream and downstream dust collecting units. SOLUTION: An upstream dust collecting unit 01 is formed by connecting a lower large unit 1a and an upper small unit 1 while a downstream dust collecting unit 01a is formed by connecting an upper large unit 1a and a lower small unit 1. The air containing dust 7 flowing through a suction duct passes through the dust collecting units 01, 01a to be sent to an air compressor while the dust 7 is removed. At this time, an electrode gap is generated between the units 1, 1a and the dust 7 is passed without being removed and, since the units 1, 1a different in height are arranged on the downstream side, the passed- through air containing dust 7a flows in the downstream unit 1a to certainly remove dust.
