Abstract
A method of and apparatus for recovering exhaust gas from a boiler 2 of a thermal electric power generating device 1 are disclosed. The exhaust gas from the boiler 2 is fed through a conduit 30 to a preheat section 21 of a powder raw material treating device 20. The heat of the exhaust gas is recovered as a heat source for preheating the powder raw material. The ash contained in the exhaust gas is recovered as part of the powder raw material at the preheat section. The sulfur oxides in the exhaust gas react with the desulfurizing component of the power raw material at the preheat section, and its reaction product is recovered as part of the powder raw material.
Claims8
