Outputs

Select the fuel type (Gas Oil or Kerosene).
Choose the nozzle pattern type—Danfoss EH/ES*, Danfoss H, S, B, Delavan A, W, B, or Monarch AR, R, NS, & PLP.
Select the nozzle size from the dropdown list.
Enter the appliance efficiency:
- If the efficiency is unknown, assume approx 80% for a non-condensing boiler, 90% for condensing.
- For burner output calculations, set efficiency to 100%.
Adjust pump pressure until desired kW output:
- If output cannot be reached, select a different nozzle size and recalc.

Important Notes:

*EH/ES nozzles are not suitable for gas oil.

**Boiler efficiencies provided are approximate guides. Consult manufacturer for precise info.

***Pump pressure requirements vary depending on fuel type:

Kerosene: 100–145 psi (6.9–10 bar)
Gas oil: 174–319 psi (12–22 bar)

Always consult pump manufacturer for min/max pump pressures.

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.

Danfoss EH & ES: reference 8 bar
Danfoss H, S, B: reference 10 bar
Delavan A, B, W: reference 6.89 bar
Monarch AR, R, NS, PLP: reference 6.89 bar

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.

Delavan W up to 8.00 GPH
Danfoss EH/ES up to 2.00 GPH, >1.10 GPH obsolete
Danfoss EH/ES only for kerosene

Always consult manufacturer for pump settings.

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.
