Performance and Application

The Delavan 75-70W1 nozzle is engineered for consistent atomization and efficient combustion across a wide range of burner types. The 70° spray angle ensures uniform fuel dispersion, supporting even flame distribution and optimized heat transfer within combustion chambers. The Type W spray pattern provides a balanced mixture of solid and hollow cone characteristics, suitable for burners requiring flexible flame geometry. Precision-machined stainless-steel metering components ensure repeatable fuel flow rates and spray quality, while the brass body conducts heat effectively to prevent fouling at the nozzle face. This design results in stable ignition, reduced maintenance intervals, and sustained performance in demanding operating conditions.
