A large silent burner. That’s the smallest of the breed, from a Primus No.4, in my hand. Marked on the burner ... ... and on the outer cap Inner cap. Cap measurements. Jet orifice is 0.5mm. Could lose a pencil down those bore-holes. 12 inches (305mm) length of fine brass gauze is rolled up and acts as a filter/fuel surge preventer. For test firing I used this Primus 702 furnace (AN date letters -1949). Mmm, not quite right. Outer cap was afflicted with metal scale around the outlet holes, which I removed. Better, getting into its stride. Settled down nicely. My pot stand. 6-pint (3.4 litre) kettle, nearly full. About the time a smaller burner takes to boil a litre of water. My thoughts on this burner? It requires a lot of priming (all that metal!) and more so than smaller silent burners, needs to only gradually be brought up to maximum output. It’s more sensitive to draughts too, which send it into underburn and that’s consistent with its probable application, heating large volumes of water indoors in a domestic setting where silent running was an asset. A footnote. Six years ago I had work to do to get an Indian burner of the same size as the Hipolito to work properly. On the left, one of those burners as purchased and on the right, the same type of burner with my addition of a tube to reduce the gap between jet and burner bell. Without that, the burner flipped into underburn constantly. Hipolito had realised a tube/riser in that location is a crucial component. John
@presscall Amazing! May I ask which model of Hipolito's stove was that burner created for? Cheers Enrique
I think THIS Hipolito in the Stove Reference Gallery Enrique but with the silent burner I have. I saw this in an online search too, also with a caption ‘Hipolito S-36’ but with no other information. It’s a design of water heater that was popular in Portugal in the 1950’s I’ve noticed. John
Hi @presscall @shueilung.2008 Perhaps No.36S burner on Hipolito No.36 stove? Hipolito No 36 Best Regards, Kerophile.
@presscall I knew I have seen this stove somewhere! But with a roarer burner and some different construction... The images are from a fellow CCS member from his tour at Algarve, Portugal! Instant water heater. Regards Enrique
@shueilung.2008 Well found Enrique! I see I contributed to that thread originally, so some bit of memory of it must have remained. So that example with the Prince replacement burner was underpowered and the Hipolito S-36 original would have been the right specification for plenty of hot water quickly. Well, I’ve now got the burner ... John
