FIELD: heating. ^ SUBSTANCE: invention refers to chemical, oil and gas and processing industries, and can be used for combustion of waste gas at factories. Device for forced combustion of waste gas includes Venturi tube with gas supply tube with conical outlet, which is installed in it coaxially and forms an annular gap in Venturi tube neck. Gas supply tube is equipped with the bell covering Venturi tube neck. On the bell a cone with cross cuts is installed. Venture tube is two-walled, hollow, and annular gap of which is installed on ventilation torus-duct. At that, internal wall of Venturi tube is provided with cross cuts offset relative to cross cuts of cone of gas supply tube as per the comb scheme. Ventilation torus-duct is connected to distribution tubes of ventilation header having normally open shutters and connection pipe for connection of forced-draft fans. ^ EFFECT: increasing combustion efficiency of waste gas in open atmosphere, and reduction of hazardous emissions of incomplete combustion. |
