Correct nozzle for oil burning Stanley Superstar 80?

[spinynorman]

Hi,

can you tell me the correct nozzle size and type for my Stanley Superstar 80 (60,000 BTUs/17.5kW per hour net to water ) please? It uses an EOGB Inter 2000 burner. The Stanley brochure specifies .65 US, 80 degree solid but the installation guide specifies .60 US, 60 degree solid, both at 130psi.

The range is used primarily for central heating, so what nozzle is best? There seem to be at least five different nozzle groups (hollow kerosene, solid kerosene, hollow, solid and semi-solid). Are these interchangeable or do I need to use only a 'solid' nozzle?

I've been using 100psi pressure with a .60, 60 degree nozzle but is there any benefit to using the original factory spec of 130psi?

its not an exact science, but you may be down on kw, for that particuliar cooker. I just use 80 deg nozzles, even on riellos and ecoflams( the pedants ..take note)

look

page 13 gives realationship for pressure and nozzle size and output.

Thanks for the link, it makes very interesting reading.

Given the awful inefficiency of the design the heat output is acceptable but I want to minimise the oil consumption if possible by finding the 'right' combination of nozzle and pressure.
