METHOD FOR REMOVAL OF GAS GAS HEATER SCALE IN FLUE-GAS DESULFURIZATION SYSTEM

摘要

the present invention is a power plant flue gas desulfurization of gas heaters (Gas-Gas Heater: hereinafter referred to as GGH ) heat the coal ash and gypsum , which is attached to a device with mixed phase I inflate the hydrochloric acid solution by spraying the lower side in the direction of the GGH boiler exhaust gas flow as for the removal of water soluble fixation , drying by steam atomizing , high pressure take steps to be hit by a repeatedly to to provide a method of removing water from a GGH heat fixation device without stopping of the flue gas desulfurization equipment and generators .
