Hi all many of you don´t know me, I start 5 years ago with the help of Nancy Hughes from Stove Team International and with a little help form Carlos Santana, since then I have learn some stove principles desings with Larry Winiarski, 2 years ago the Global Alliance invite me to attend the wood cooking stove forum in Lima Peru, in the opportunities brought along a hybrid stove Rocket/TLUD similar to the DK stove.
Here is some pictures of the Jiko Bomba casification cookstove.
The first shows the two part of the stove with pellet as fuel in the firebox before fire is lit.
Second show the stove burning.
The third the same, in the end of the gasification.

And he considers the multiple challenges faced by poor people in the Himalayas, where it is very cold, and there is very little wood available.

All stoves presented above are of TLUD types, but the combustion is improved by using pre-heating and counter-flow burning mechanism. The one intended for palm kernel shell utilizes diffused-combustion mechanism, in addition to pre-heating and counter flow mechanism.
