    This is my 1939 ‘rocket stove’. These type of industrial stoves, often referred to as 'rocket stoves', were used for starting hot bulb engines, operating portable furnaces and more depending on the number of burners.

    The model 734 has three burners but similar Primus stoves have one, such as models 85 and 702, two or even more than three burners. Fount holds 4 UK pints. It goes well but is not excessively noisy. This model was made in 1939 and is stamped AD 17. When I run it I take the three flame rings off as they are seemingly unburnt.

    That's very useful rocket stove! :thumbup: I use one for summer cabin heating on early spring and late autumn before fireplace is on full power to produce heat.

    Any same diameter steel/brass tubes would work as substitute for original flame tubes.

    I found the correct diameter steel pipe from a car repair shop: exhaust pipe!

    Cheers

    Thanks for that, good point, I reckon I have a bit of metal tubing lying around. I might create a set.

    More importantly, I spend some time in an old cold building and you have given me a better idea than the old Aladdin kero heater.

    Thanks Tony, that'll work too if my pipe is wrong size.

    I think that power of 734 is something like 5-6 kW so I heats up my cabin quite fast on full power. Then I reduce pressure on tank otherwise cabin gets too warm.
