# Oil Burner Nozzle size

• posted on April 3, 2009, 2:02 pm
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 http://www.thestuccocompany.com/hvac/Oil-Burner-Nozzle-size-37388-.htm : 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 .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
