[Stoves] High mass space heating options Re: Rocket Stove for the PLACE

Sun Oct 9 00:42:40 CDT 2011

Alex and all,

That is an excellent observation about the "steady state" similarities.

But having a "regular fire" that is not steady state (as in rising to  
a high fire and then progressively dying back) as the source of the  
heat is not necessarily any better or any worse.

The issue about the TLUD is that its "steady state" can be as a nice  
stable cooking fire, but it can also be steady as providing a raging  
flame.  This can be easily done with simple forced air (FA) methods  
such as fans and blowers into the primary and secondary air inlets.   
And the discussion is currently focused on heaters for  
developed/affluent/with-reliable-electricity societies.

Steady does not mean small nor large.  If the high mass stoves need  
high heat, the TLUDs can provide it.  And with the evident sizes of  
these high mass stoves/heaters, there is sufficient room for TLUD fuel  
chambers (pyrolytic reactors to create the gases) to have both  
intensity and duration (such as for 45 minutes to 2+ hours) with a  
single batch.

The high mass heater-stoves is an application or use of the heat.  I  
have much to learn about that, but what is known about TLUDs as the  
possible devices to provide the heat gives us great confidence that  
the combination of TLUDs and high mass heaters can have great potential.

And when we have a few successes in the affluent countries, that will  
spur us on to do things for the developing societies in cold climates.
