Abstract

The invention relates to an adjustable swirl blade assembly and a flat flame burner comprising the same, and belongs to the technical field of combustion equipment. The adjustable swirl blade assembly comprises an adjustable swirl blade assembly body and a blade transmission device, and the body comprises a central rectification body, an outer cylinder, an inner cylinder and a plurality of rotatable blades which are coaxially arranged; the blade transmission device comprises a plurality of blade rotating shafts which are fixedly connected with the blades and are used for controlling the blades to rotate, transmission connecting rods which are fixedly connected with one ends of the blade rotating shafts in a one-to-one correspondence manner, a total connecting ring which is connected with the transmission connecting rods and surrounds the adjustable swirl blade assembly body, and an operating rod which is connected with the total connecting ring and is used for controlling the total connecting ring to move; and each transmission connecting rod is formed by rotationally connecting three rigid connecting rods, and two rotating pairs with non-coaxial lines and non-parallel rotating shafts are formed at the joint. The technical problem that in a traditional device, control over blades is not accurate is solved, a combustor can operate under the small-load working condition, the large air-fuel ratio working condition and the condition that the fuel heat value fluctuates violently, and stable flat flames are formed.

Description

technical field [0001] The invention belongs to the technical field of combustion equipment, and relates to an adjustable swirl vane assembly and a flat flame burner containing the assembly. Background technique [0002] The flat flame burner was used in industrial production in the mid-1960s. Using the centrifugal effect of the rotating air flow, it rotates and expands along the channel of the expanded burner brick, and sprays out a disc-shaped flat flame that is close to the furnace wall and spreads evenly around. The flat flame burner can improve the temperature uniformity and radiation ability of the furnace wall. It can reduce the height of the furnace and reduce the heat dissipation area of ​​the furnace wall when applied to the hot rolling heating furnace, so it can save fuel. The flat flame burner has been widely used for decades. industrial applications. [0003] The traditional flat flame burner can form a stable flat flame under the rated power. But there is a l...
