[Stoves] continuous flow steam injector

[frank at compostlab.com]

Many years back I made a steady steam producer to aid in distilling over
unionized ammonia. A flow through reservoir (a little faster than the steam
being produced) was placed at a level equal to the steam maker. As the water
level went down from making steam (inside the stove) the water was replaced
from the outside water flow through system under no pressure. (gravity)  If we
have a coil of copper or U shaped filled with water to the height of the flow
through outside system. The inside water would stay steady at the height of
the outside reservoir. As steam was produced as the tube got hot there would
be a ‘start up’ time. Once the water started making steam the inflow could be
adjusted to a steady rate equal to the water changing to steam.  

If we want the draft to control the air flow we need a steady supply of
moisture. But I think it could be more interesting to pulse in the moisture
(steam) for better mixing and increased flow – if it will work as I think it might
