FIELD: mining.
SUBSTANCE: scraper is inserted into pipe of coil of furnace by means of flow-carrier, performing cleaning of pipes by destroying coke sediments with plates of moving scraper. At increasing gradient of pressure in the coil to 0.2 MPa as a flow-carrier of the scraper there is used a raw material on which the furnace operates, and when gradient of pressure in coil is increased to 0.4 MPa, poor coking oil product is used. The scraper for cleaning corresponds to a rounded element with head 2 and tail parts 3, and plates made in form of pins 4.
EFFECT: reduced duration of furnace cleaning process, prevention of furnace shut down during cleaning and upgraded ecological characteristics of installation.
