[Stoves] Wood stoves in Ukraine

[Crispin Pemberton-Pigott]

Dear Friends

The project is run by OperationAid, a Swedish charity.

The design look awful.  Note that it can cook.

I believe the vertical weld on the side towards the back separates the combustion chamber from a heat exchanger (the function of the rear compartment) and, in general, is typical in that respect of Russian wood stoves over the past 100 years.

To maximize the efficiency of the heat exchanger there should be a hole from the top of the combustion chamber horizontally into the chimney about 45mm square, and the chimney should draw the smoke from ~75mm from the bottom of the back chamber. This will cause the heat exchanger to have roughly the same temperature all over - maybe a 50 degree difference top to bottom.  When you have limited materials and skill, that is how to build it.

If the chimney is offset to the right back corner it allows a slightly larger pot to be placed on the stove, and makes more space teo heat water in a kettle while cooking.

Regards
Crispin
