They have developed a various biomass stoves ( Kompor Biomass ) The fuels also vary from chopped woods/twigs, pellet, palm kernel shell, hazelnut kernel shell, corncob, etc..
And they have a nice collection of YouTube videos:

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.
The latest one

is devoted for institutional cook stove or small restaurants.
Very recently, we have also developed a new rocket stove. The combustion in this new rocket stove is improved by introducing counter-flow burning mechanism.
