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

Mon Oct 10 09:39:36 CDT 2011

That is precisely the reason I am thinking about combining these two concepts; biomass/char and mass absorption and transmission. I want to produce char as a co-product of the heating cycle, cooking will also be a secondary consideration.
My desire is to find a design that will benefit and further enhance each of these concepts. I am not particularly enamored with the idea of continuous "fire" tending, I do like the notion of building one or two very hot, short duration fires and then walking away to have the mass regulate the heating needs of the space.

As I said above creating biochar in this process is equally important to my purposes. I really hate the idea and throwing off the "waste" heat from the char production, as I also do not like the idea of burning up the char in a continuously fed heating appliance. It seems to me that it may be possible to doubly enhance the efficiencies of each of the these two processes by combining them.

Does this seem desirable to any others here?

If this is going to become a busy discussion I will need to set up a different email acct for it, this is my studio email and it gets enough activity on it's own. Is this a discussion that should be moved to a list server?

  Alex:  I believe the most appropriate answer to your final question below ("What do you see as the advantages of combining these two approaches?") is one you gave yourself:  ("...a desire for char ...").

     The beauty of high mass heaters is that they mesh well with a batch process - the main (only?) drawback of char-making stoves.

  Paul,
  The TLUD configuration has it's advantages and disadvantages, like any 
  system. One advantage is it's steady state energy release. High mass 
  heaters strive for a similar result. It seems a bit redundant to pair 
  the two. Perhaps it depends on other considerations like a desire for 
  char or an available particulate fuel supply.

  There are some folks doing fine work at the Masonry Heater Association.
  http://mha-net.org/
  They have done a lot on emissions, efficiency and durability.
  They have looked into Down feed rocket configurations.
  I'm not sure if they have quantified losses between firings, or seasonal 
  efficiency.

  Its a simple concept with lots of technical details.

  What do you see as the advantages of combining these two approaches?
