River E. : A quick review of the rocket stove
, its past and future are in order !
We are at a turning point in the future of Rocket Mass Heaters
, 20 years ago Rocket Stoves were built out of materials that ' let ' the Stove survive the high Temps
that allowed the Incredible efficiencies that their unique structure was capable of producing!
Since then there has been the introduction of materials that were lighter but still capable of surviving the high temperatures! Due to less heat being lost to heat energy
penetration/absorption into the Thermal Mass, the Newer built Rockets Reached their extremely high operating temperatures much more quickly, further decreasing
energy lost to earlier ' cold ' start up inefficiencies!
Tomorrows Rocket Stoves, are being made of Ceramic like materials capable of handling the Rockets extreme temperatures, with only slight heat absorption ,quickly
glowing white hot, producing their high efficiencies that much sooner !
Some Castable Ceramic Cores are now being produced for the D.I.Y. Rocket Stove
Mass Heater Market. More manufacturers will enter the market, I am not personally
ready to buy and generally can not recommend the purchase of something so new to the market !
A quick review of how a rocket stove works and a quicker look at its future and we are done ! We generally say that a 6''-8'' diameter Rocket Stove needs frequent
feedings of small very dry wood to allow it to achieve its high efficiencies , usually 1-2 Xs an hour until the Heat Riser part of the Rocket has reached temperatures that
will cause the next wood chunk to spontaneously burst into (primary )flame! Thereafter it is simply a mater of feeding it wood nearly every hr, over a 6-8 hr period to
store 20-25 hours of heat storage. This is usually considered minimal attention for successful operation of a Rocket Stove!
With all the advances in Rocket Stove construction, we await the further demonstration of long term viability of Rocket Stoves that can be batch loaded, even then the
only way we will enjoy the Rocket Stoves Vaunted High efficiency is with frequent attention !
Anyone not willing to live in close proximity to their Rocket stove should
look elsewhere for a heating source !
For he good of the Craft! Be safe,keep warm! PYRO Logically Big AL !
