Medium-velocity burners are the burners that the POC (products of combustion) velocity from the burner exit peaks at 40 m/s. These burners are usually used in melting, steel preheating and hot gas generators. Although usage of these burners is widespread, care should be taken while setting combustion parameters. One of the drawbacks is starting them with air pressure less than design pressure. This leads to POC velocity reduction converting the burner to a low-velocity type. Sometimes they are used instead of high-velocity burners, that eventually leads to non-uniform heating. These burners are presented in single and dual fuel mode. Also, the burner head is resistant to high temperatures.
This wide flame dual fuel burner features short and wide flame pattern in broad stability range. This burner is designed to fire combustion chambers that have a limited length but with sufficient width to allow the flame envelope to develop. This burner has provision for gas pilot and ultraviolet flame supervision device. Both gas and oil flames are tile – stable over a fairly wide range of air/fuel ratios. The burner can be used in cold sealed-in combustion chambers with light oil or gas.
