Holey Roket scheme

The briquette burns just from one side and through the hole, which makes a steady burn with less smoke. Briquettes are fed continuously from the side of the stove, where you can add a door to manipulate the volume.

We have to know the briquette material by default is not burning as well as fire-wood or charcoal, that is why it needs an efficient combustion system to burn the smoke emissions with high enough temperature and directed-to-pot fire to provide faster cooking. The hole in the briquette acts as a combustion chamber in itself, making the flame hot enough and directed straight in to the centre of the pot.

Here are some examples of existing stoves using briquettes.


The Holey Roket Stove is based on the Rocket Stove technology for firewood developed by Larry Winiarski and Aprovecho research center. Please visit a great resource website by clicking this rocket stove image:

If there are specific efficient stoves already in use by the local communities, best way to introduce biomass briquettes is to merely adapt existing cooking systems. Here are few examples how briquettes could be used in some existing stoves world-wide.


Many thanks to Richard Stanley, Dr.Larry Winiarski, Ken Goyer and Aprovecho research lab (2008 Stoves Camp) for great contributions to the project!

  1. Dear Mr. Oblak,
    My name is Marko Verbic. In the Ministry of Agriculture, Forestry and Food ot the Republic of Slovenia I havew been working on development assitance for some time. I am trying to make contact with you regarding the Mdula stove as well as the above mentioned stove. My colleague Mrs. Bojana Hocevar, former permanent reprresentative of the Republic of Slovenia to FAO and WFP in Rome and a very good friend of mine has spoken to the executive director of WFP in regrad to possible use of your stove in Africa as a part of WFP programme. Can you give me present e-mail address to be able to explain you the whole story in detail?
    Lep pozdrav iz Slovenije
