[Stoves] Can anyone identify the manufacturer of this stove?

Andrew:



Your last line is most interesting for designers to consider.



About the Redwood scale/metric: See here<https://www.collinsdictionary.com/dictionary/english/redwood-seconds>.



Diesel and heating oil are identical.  Both change seasonally so that the summer diesel doesn’t “freeze” in winter (go jelly-like).



Kerosene = paraffin anywhere.  The composition includes (usually) C9H20 to C15H32 which is typically missing from diesel and biodiesel.



Kerosene usually stops at C20H42 while diesel includes C22H46 which explains the different Redwood numbers.



Within the kerosene family there are two kinds: illumination paraffin which has an additive to make the flames shed more light, and power paraffin which is unadulterated.



One thing is clear, there is still progress in creating high performance liquid fueled appliances.

I can't help with the stove but have used something similar where the wick was wound up  by a thumbwheel, you wound it just high enough for the flame to remain blue. They were "aladdin stoves" and continue to be available for greenhouse heating. Using heating oil/kerosene in these tended to block the wick and the wick could not be turned up as far so lower power IIRC.



The fuel was paraffin which ceased to be available cheaply decades ago in UK. kerosene is generally a heavier oil and used for heating as 28 second heating kerosene.  Gasoil and diesel are  the same and 35 second redwood. A higher grade kerosene is available for the wicked AGA cookers, it's still 28 second but much more expensive. With these cookers once they are up to temperature they act in a vaporising mode and the wick doesn't burn as it is below the flame.



Gasoline in UK is petrol.
