2.5mm Oil/Kerosene Nozzles
Posted: Wed May 20, 2020 5:10 pm
I just wanted folks to know that there are some cheap air atomizing nozzles available on eBay for $20 on eBay.
I bought the 2.5mm nozzle, and replaced the interior O-ring with a steam rated Viton O-ring from McMaster Carr. (5 pack for $5)
The nozzle is intended for air, but I just wanted to let folks know that with this O-ring substitution this nozzle works on steam.
Now I did experience flameouts, but having a propane burning nozzle also running worked great as a pilot light.
This was a first test for me, it's certainly not operating perfectly - but boy did I notice the BTUs! For my needs, it will be something that I will be keeping on my boiler. Adjusting the steam supply and fuel supply is a little finicky.
5sec clip showing operation.
some wood embers act as a pilot light during a flameout.
