IPC: F28F19/04
Filed: 2001-06-07
Abstract: PROBLEM TO BE SOLVED: To remove SO3 in flue gas, without being accompanied by the sharp increase of device cost and running cost. SOLUTION: This device is provided with an SO3 separator 10 which separates and removes SO3 from the flue gas of a boiler 1 before treatment with a wet desulfurizer 7. The SO3 separator is equipped with a shell and tube type of heat exchanger, and it cools the flue gas to the dew point of H2 SO4 gas or under by passing the flue gas on the shell side and boiler feedwater on the tube side. The SO3 components in the flue gas react with the moisture in the flue gas and turn into H2 SO4 gas, and the generated H2 SO4 gas condenses and adheres to the surface of a tube. A part of the SO3 components can be removed from within the flue gas by washing the liquid-form H2 SO4 adhering to the surface of the tube in water. Hereby, a wet electric dust collector 8 to be installed downstream of the wet desulfurizer can be downsized, and the device cost can be reduced as a whole.
