Oil Burner Nozzle size

Apr 03, 2009 3 Replies

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.

: 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
