METHOD FOR PREVENTING INACTIVATION OF FLUE GAS DESULFURIZATION APPARATUS

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.
