The PrimeFire 300 burner for glass furnaces creates a fan shaped flame with low momentum, which has a lower peak flame temperature. This results in lower operating crown temperatures and lower volatile transport rates. An adjusting mechanism on the burner allows you to change the length and width of the flame shape to suit the melter width and the required temperature profile. The PrimeFire 300 burner improves flame luminosity which increases radiant heat transmission to improve furnace efficiency. The uniform heat distribution from the burner improves product quality and throughput and extends the furnace refractory life.
