ABSTRACT
Our paper deals with the balance of chlorine in coal combustion and flue gas desulfurization based on
measurement results acquired at two different boilers of the CEZ thermal power plant in Melnik, Czech
Republic. In bottom ash and electrostatic ash 30–35% of chlorine remains and more than 60% chlorine enters
flue gas desulfurization. Almost all chlorine in flue gas entering flue gas desulfurization is removed from 90%
in limestone scrubbers. Only up to 8% of chlorine content leaving the scrubbers is emitted to ambient air.
