AVAN STOVE made by Monk Viravat Charoenbenchavong

I'm a Buddhist monk in a rural area, approx. 120 km from Bangkok, Thailand, south East Asia. I finance the Avan stove of your design. It works properly as per http://prasartporn-update.blogspot.com/2008/08/wood-gas-stove-dr-sai-bhaskar-reddy.html .
I have asked him to inject steam to the hot area at the end of the stove. He has done it wrongly. The idea is to use "capillary" by hanging/placing a small water container just outside the stove and using a wig to transfer water to a steam pipe inside the stove. I think it would produce "water gas" so as to reduce the wood consumption.
I ask him to try again.
Thank for the design
