Oil Burner Nozzle size

Posted by CS on April 3, 2009, 10:02 am

I am working out the nozzle size required for a oil burner buring 35
sec oil. Boiler rating is input 18.4kw, output 16.6kw and is non
condensing. 18.4kw input equates to 1.84 ltr of diesel (1l = 10kW).
This equates to 1.55 kg diesel from a 0.40 nozzle at 11.3 bar.

Grateful for confirmation

size doesn't matter. It's how far it squirts that matters most.

dundee had written this in response to

here is how it goes-
heating oil gross CV 40 kw per US gallon at 180 psi(12.4 bar)pump pressure

Oil Input (US gallon)= Input/gross CV of the heating oil
=18.4kw/40 = 0.46 US Gal per hour

Nozzle size = oil input /pump pressure factor
=0.46/1.34 = 0.34 US Gal per hour

Therefore nearest available nozzle size is 0.4 US gal per hour
