Extra Information

When fuel was cheap, excess air was used to aid temperature uniformity within a furnace load by 1)reducing the hot mix temperature, 2)preventing stratification, and 3)enhancing convection heat transfer. With high velocity burners that induce re-circulation of furnace gases, the recirculating gases produce the above three benefits that formerly required excess air and therefore wasted fuel. High velocity burners are designed to increase convection heat transfer, regardless of the temperature level or loading in the furnace. This convection heat transfer may incidentally heat the refractory walls as well as the load, resulting in considerable radiation heating. The exit velocity of combustion products from burner head is in range of 70 to 230 meters per second velocity. High velocity burners typically have lower NOx emissions than other flame types because of their ability to pull furnace gases into the flame. High flame stability makes these burners great for being used in a wide range of excess air from very low to extremely high.

You can order SSECO’s high velocity burners with metal (cast iron, stainless steel and etc) or silicon carbide or multi-channel burner heads (HHG/M,C and HHG/S and DCHHG/S models respectively). SIC and SI2C types have higher temperature resistance (approaching 1600°C ), excellent thermal shock resistance and high thermal conductivity. You may also order these burners in medium velocity type which is called HMG/S.
