In this model, I have provided opening for the air on the sides for the following reasons (see the logitudinal section for deatils) :
1. It is easy to construct and steel mesh or grate is avoided, which is external raw material and not easily replaceable in the villages. So only bricks, clay and cow-dung is used.
2. The opening for air is choosen sideways, it is convinent to keep the opening open for air movement and removal of the ash without disturbing the wood or sticks. Would also push the fire towards the opening of second stove creating two updrafts (of course less intense for second stove).

I am interested to know how your stove design has worked in practice. Do the cooks like it?
Good idea to omit metal grates -- they often get lost or damaged before the masonry parts.
I can see how the two burners, one hotter and one more cool, could be convenient for preparing multi-dish meals.
Have you considered a vertical feed tube, so that the fuel does not need to be adjusted as often during cooking?
This was one of the reasons for the J-tube "rocket stove" design, which can be built easily with earthen or fired brick. See www.rocketstoves.com.
There is a hand-drawn diagram at www.patternliteracy.com/rocketstove For cooking one would omit the barrel and thermal mass, and cook atop the "heat riser."
I believe that having a metal grate is a very good option. It is not necessary to have it installed permanently. It can rest freely on projections inside the stove opening so it can be easily removed or replaced.
