| 摘要 |
The present invention relates to a method by which inactivation of a flue gas desulfurization apparatus is predicted and prevented in advance. According to the method of the present invention which is used to prevent the inactivation of the flue gas desulfurization apparatus which treats an exhaust gas of a coal-fired boiler, an inactivation potential which is an inactivation index is calculated from alkaline components such as Na, Ca, Mg, and K contained in ash of the exhaust gas, and, in response to the change, a pH control system setting value is adjusted and a drainage control system is controlled for operation management with respect to the flue gas desulfurization apparatus. |
