Method of recovering exhaust gas from boiler in electrical power generating device using combustible material as fuel and apparatus for performing such method
Abstract
A method of and apparatus for recovering exhaust gas from a boiler of a thermal electric power generating device are disclosed. The exhaust gas from the boiler is fed through a conduit to a preheat section of a powder raw material treating device. 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 powder raw material at the preheat section, and its reaction product is recovered as part of the powder raw material.
