Fellow Members, Worldwide you can come here 24/ 7 and talk to someone who wants to talk about what you want to talk about !
A nearly painless way to get the paperwork out of the way and we'll move on ! look at the space next to your name and L@@K at mine! Below is a link to explain
much of the ways to quickly bring you up to speed and allow you to use the range of resources available to you as a member !
From your question it appears that you are not talking about a Rocket (Cook) Stove, as it generally does not have a true fire box. This would normally leave us
with a Front loaded, or frontally fed Rocket Mass Heater, RMH, that needs frequent attention to continually move the firewood forward to the front of the Burn Tunnel to allow the wood fuel to be burned and its Wood gases then consumed in a freaky hot and very clean fire - So there is a sweet spot and a lot of
adjustment is needed !
Second, most popular and most common of the 100,000 or more Rocket Mass Heaters RMHs is the Vertically fed J-bend style RMH that delivers the wood fuel
directly to the sweet spot in the Burn Tunnel where the lower tips of the small very dry fine split fuel are comsumed and the wood continually self feeds as the tips
are consumed ! Here the Fuel wood is loaded from the top of the Feed Tube (vertically) and the distance is pre-set with a generally accepted ratio of 1 : 2 : 4 ,
representing the depth of the Feed Tube, the length of the Burn Tunnel And the final height of the Heat Riser ! this is more or less determined by
The RMHs size!
Third, and the new boy on the scene is the only RMH that can truly be said to Have a true Fire Box. Because it is usually a front batch-loaded system that is
fed a calculated loading of wood it is generally called a batch box style RMH
This is a new toy with only a very narrow range of shapes and marked detentions that have been found to work so-far but yes the Batch Box's size,
shape and distance is very carefully calculated To promote nearly complete combustion of all the wood gases !
This is where I recommend that you go to Rocketstoves.com to pick up your PDF Copy Of 'Rocket Mass Heaters' ! This is the book responsible for nearly
all RMHs built to date and 95% of all the 1st time builds (that worked ) With this book you can come to Permies knowing that you will be using the same simple
terms to describe the Size, Shape and orientation of the parts both to themselves and to each other !
"The Book'' will also save you time frustration and money, as you source the correct parts and assemble them harmoniously into your Massive Monolithic whole!
We all started standing where you are today, if there is a RMH in your future we will help you find it ! Big AL !
