The VA Burner offers high turndown of 20:1
Selas’ versatile VA-Burner employs the variable-area principle. That is, the position of the burner tip changes as the pressure exerted by the fuel mixture upon the burner diaphragm changes. When mixture pressure exceeds that of a retaining spring, the diaphragm immediately responds by moving the tip to a new position which provides an enlarged port area. This special design feature makes a 20-to-1 operating range possible.
Features and Benefits
- Faster heating. The high speed of radiant heat transfer and greater intimacy between the heat source and the workpiece assures faster heating without flame impingement.
- Finer control. Burners focus radiant heat and, when necessary, pattern the heat to yield different degrees of intensity. Uneven heat losses in a furnace can be offset by directing radiant heat so it is proportional to losses.
- Improved product quality. Faster, more uniform heating frequently improves product quality as it minimizes scaling, decarburization, and the oxidation of materials.
