VENTURI FUEL DELIVERY
Using CFD modeling, gas injector design and positioning have been optimized to ensure more complete combustion through the uniform mixing of air and gas. This decreases NOx emissions and guarantees the highest possible efficiency for all burner firing rates.
Robust and simple injector design ensures robust and reliable performance with high turndown.
