*EH/ES nozzles are not suitable for gasoil.
**Boiler efficiencies provided are approximate guides. Consult manufacturer for precise info.
***Pump pressure requirements vary depending on fuel type:
This nozzle calculator serves as a general guide for estimating outputs based on Delavan, Danfoss, and Monarch nozzles at specified pressures. Follow manufacturer instructions when available.
Different nozzles at same pressure produce different throughput. Verify pump pressure and nozzle size.
Example: 0.50 GPH EH/ES nozzle at 125 psi → ~20.12 kW. Swap to H/S/B → ~22.43 kW.
EOGB not responsible for misuse. Verify info for your application.
All figures based on OFTEC fuel densities (Kerosene 0.79kg/lt, Gasoil 0.84kg/lt). Nozzle capacities from Danfoss/Delavan.
