ECLIPSE
In general, the standard disc burner is applied for surface heating, hence the burner can be operated close to the working material for effective heat transfer without creating any hot spots.
A disc shape flame is the main characteristic of the disc burner as its name implies. The disc shape flame is accomplished by forcing the air to swirl down the burner body utilizing what is known as the Coanda effect. Due to the swirl, the flame will spread along the wall of the burner tile, forming a disc shape flame, The disc like flame shape accounts for the burner's uniform heating characteristic with no forward motion. The burner tiles are designed to aid in achieving and maintaining uniformity in the flame shape during operation.
Air and gas are mixed at the nozzle; hence the air and gas enter the burner separately. Preheated combustion air can be used if a heat recovery system is available. The disc shape flame is achieved due to the swirl of the combustion air. As the air meets with the gas at the nozzle, combustion begins taking place. The flame, due to the swirling effect of the combustion air, will hug the wall of the burner tile, thus creating a disc shape flame, The burner when operated within its proper capacity range will have no forward motion. The standard disc burner can be operated continuously for long periods of time.
