Prime offers cookstoves whose combustion chambers are optimized to the fuel type that is preferred. This ensures an even higher combustion grade and efficiency. It is possible to purchase an extra combustion chamber and use combustion chambers interchangeably for the cylindrical stove version. This increases flexibility and takes into account seasonal availability of cooking fuels.


Burning chamber optimized for fuels such as chopped wood/woodchip. Biomass briquettes can also be used. Fuelwood should be cut into smaller sticks and densely arranged in the fuel chamber. Woodchip should be poured into the burning chamber before densified by gently shaking the burning chamber. There is no need to arrange the fuel when using biomass briquettes. Dried corncobs or cow dung can also be used. This burning chamber can also be used with small scrap wood to better conserve environmental resources, thus giving an even better carbon footprint.


Burning chamber optimized for granular fuels such wood pellets, coal pellets, palm kernel shells, hazelnut kernel shells and similar biomass. Simply pour the granular fuels into the burning chamber and shake gently to densify the fuels. The ease of use due to lack of fuel preparation and its cleanliness makes this burning chamber ideal for indoors cooking commonly performed in peri-urban and urban areas. Cooking with the use of processed fuels, such as wood pellets, increases stove efficiency and removes additional health damaging fumes.
