North American 4441 Model Tempest High Velocity Low NOx Gas Burner Use At Gas Burner
North American Tempest High Velocity Gas Burner
The 4441 model Tempest has gained acclaim for its high velocity jet action and superior recirculation promoting capabilities.
These two features bring both the quality benefit of close temperature uniformity and the productivity benefi t of safe higher
heating rates up to 1650°C (3000°F).
Additionally, a variety of tile material and outlet shape choices provide fl exibility in installation with a “flame fitting” to the shape
of the combustion chamber.
| Combustion Air | 0.08-10.3 kPa (0.3-41.6"w.c.) air pressure, max 177°C (350°F) |
| Fuel | Natural gas with propane gas versions available in the -1 thru -4-B sizes. Gas pressure varies per size with 4.7 kPa (19"w.c.) is maximum required at design capacity, for 6.9 KPA (27.7"w.c.) combustion air pressure, stoich ratio. |
| Flame Supervision | Flame rod or UV detector Consult National Safety Standards and insurance underwriters for specific flame supervision requirements. |
| Control | Excellent performance with all control systems |
| Air Flow, not burning | 219Nm3/h |
| Gas Pressure UG | 39.2mbar |
