Technical concept
 DeNOx Gas burners: Free gas jet |
FreeJet gas burner forms a narrow funnel, just following the opening angle of a free gas jet up to the open furnace chamber. This low turbulence gas flow is mixing with combustion air and starting combustion much later than conventional burner type, giving the gas enough time and space for self-carburization, to for small carbon particles, which increases the emissivity of the gas flame and lets the flame temperature drop down more than 50K. | |
 |
Any direct contact of natural gas with the refractory material of the burner block must be eliminated. Considering this, the design of the burner includes the former function of the burner block, forming the narrow gas funnel up to the hot end of the burner block, up to the direct contact with the furnace chamber. | |
| DeNOx Gas burners: Separating cooling from combustion air | ||
 |
This requires cooling of burner heads by cooling air and cooling water and a completely different design of burner block. | |
