NOVELTY - The method involves performing anaerobic heating of trees soaked with creosote at a temperature of up to 650° C. The emission gases emitted from soaked wood are constantly heated and continuously directed to the fire filter. The fire filter purifies gases to the level of permissible emission purity. The energy released in the process is used for the gradient of maintaining the parameters of the appropriate temperature in a given reactor. The process is strictly controlled automatically by an appropriate control system from the moment of loading to unloading the entire load. A fire filter is preovided with an appropriate catalyst and a graphene filter at the exhaust manifold to ensure the purity of emission gases at a high permissible emission level. USE - PIRO-PO method for used railway sleepers and other types of wood products impregnated with creosote.
