he paper presents universal technology of cleaning flue gases from boilers, where municipal waste and dangerous waste (medical as well), coal, lignite, mazout are burned. This technology allows us to remove pollution from flue gases to any lower level. The use of oxidizer for NO oxidation to acid anhydride enables us to remove it in a reaction with Ca(OH)2, similarly to SO2, SO3 and HCl. Removing dioxins, furans and heavy metals from flue gas is done by injection of active charcoal to flue gas before a fabric filter. The dose size of oxidizer and active charcoal affect the effectiveness of removing NO and dioxins, furans and heavy metals. The analysis of exploitation costs was made for efficiency of cleaning flue gases to the level of the emission of pollution that is in the Waste Act [1] . The technology was developed on the basis of research results from the pilot installation.
