Selas Model K Burners
7-inch size with either cast iron or special alloy components. Employs an air-gas mixture impinging directly on the finned refractory surface to produce a high-density flux of maximum radiance.
The Model K Series is available in a 7-inch size with either cast iron or special alloy components and employs an air-gas mixture impinging directly on the finned refractory surface to produce a high-density flux of maximum radiance. The flame itself is not the source of infrared radiation. Its function is to heat the refractory to temperatures of 1650° to 2000°F. The refractory then emits infrared energy in the micron range most efficient for the product heating process.
