FIELD: collection of hot gases emanating in production processes.
SUBSTANCE: the invention is dealt with collection of hot gases emanating in production processes and may be used for collection of hot gases on fumarole fields of the active volcano containing water steam and corrosion-active gases. The device contains a collector made in the form of the sealed tunnel provided with two units of gas withdrawal. The tunnel represents a self-supporting curved arch made out of the ceramic heat-insulating acid-proof materials and mounted with use of an acid-proof metal formwork, and protected from above by a sealed acid-resistant casing. The technical result is simplicity of mounting and operation of the sealed heat-insulated device for collection of hot gases with a high share of water steam and corrosion-active compounds.
EFFECT: the invention ensures simplicity of mounting and operation of the sealed heat-insulated device for collection of hot gases with a high share of water steam and corrosion-active compounds.
