Boiler nozzle sizing

[Bogart]

Probably been asked before but cannot see where. Inside my boiler there is written nozzle 1.25 x60 W. In an envelope attached to boiler is a new nozzle marked 1.25 x 60 S are they compatible? Boiler is an old Boulter Camray.

The first number is capacity (tho this will alter depending on pump pressure) the second number is spray angle the letter refers to spray pattern W is what you would probably expect on your boiler as no doubt it has a riello burner?
If your going to play with different nozzles you need pressure gauge and commission analysis equipment to make sensible adjustments.

Yes is a Riello boiler. Will tell my man which nozzle to bring when he pops round later this week.
Thanks

If I remember right, the W is a delavan nozzle and the S a danfoss. Different manufacturers use different codes for the same thing.

Her is coming over tomorrow so will get it clarified.

All taken a bit of a nose dive as poor soul broke his leg day before due. Any excuse not to turn up. So being curious I took out the old nozzle and is a Danfoss F7N this is marked 1.00 60 ES and 3kg/hr. Now doing a bit of conversion work I find that 1 US gallon in weight equals a smidge over 3kg. Now I think yes the 1.00 then equates to 3kg/h. Confused now as to why label in boiler and new nozzle states 1.25 which obviously means 1.25 x 3 = 3.75kg/h. Is this any big deal? Tried ringing my guy but his phone has been off for days.

You can’t change nozzles or anything combustion wise without the knowledge and equipment to set it up.

Different nozzle sizes, pump pressures and air settings are required to get the required output.

You can’t just change something without cocking up combustion. Even like for like nozzle changes typically require adjustments.

You need to find an oil guy.

I have one but like I say is somewhat indisposed. Will be weeks to get another.
