FIELD: power engineering.
SUBSTANCE: device for cooling and/or cooling of a liquor gun, comprising at least a liquor tube for supply of liquor and chemical products into a furnace of a waste-heat recovery boiler. The device includes an external casing string, which defines a space, to which pipelines are supplied for water and steam supply, in order to form emulsion, or a pipeline for emulsion supply, formed by water and steam, and the surface of which is equipped with holes, such as pores or cavities, to drain emulsion via the external casing string, which is formed with water and vapour.
EFFECT: increased efficiency of gun cleaning and its durability.
