<p>The invention relates to a structural design for flare devices and can be used in the petrol and gas, petrochemical, chemical, coke-chemical and other industries where gases, which are not used in production processes and/or accidentally discharged into the atmosphere, are to be neutralised. The inventive flare device for smokelessly burning a gas,without forcedly supplying air and/or water steam and/or water, operates within the entire design range of flare gas flow rate by increasing the specific gas-environment air contacting surface. The flare gas is mixed with environment air by means of flat streams of exhausted gases (minimum thickness-maximum cross-section perimeter). A gas-dynamic resistance is reduced by movable gas gates having any required shape, preferably in the form of a bluff body. Gases flowing around the movable gas gates and coming out of heads are divided into flat streams flowing in diverging directions at an angle to each other and are brought into contact with the environment air on two sides, thereby being completely burned. The number of heads, the number of the movable gates therein and the shape are determined according to the parameters of a flare system. The permanent minimum flare gas flows which pass to a burning area by thin jets at a design rate,are mixed with environment air and are smokelessly burned.</p> |
