[Stoves] Ceramic fiber insulation

[Ashok Mathur]

Dear GrahamI am not clear as to the causal link between the type of insulation used and amount of particulate matter released?
Would it be more correct to say that the right amount of insulation is needed to burn the fuel with least amount of particulate matter?
Literally a thicker layer of mud will reduce the particulate matter to the same level as a thinner but expensive CFI?Pl correct me where I am wrong.RegardsAshok

 Dear Julien,
 
 You raise a valid point but like many such concerns one has to balance one danger against another.
 A classic case is the removal of asbestos from renovated buildings.
 Is it better to leave it untouched or remove it and put cancer threads drifting in the air?
 
 However with CF used in the open for wood stove fires in SSA countries I doubt if this question will ever arise!
 Using such insulation will cut the amount of smoke from such stoves and so reduce the lung ailments that plague millions!!
 
 Yours,
 
 Graham
 
 P.S. Do you have any useful contacts in SSA countries?

    Dear Graham; 
  Using ceramic fiber insulation (CFI) is an interesting idea.  It could be used for building stoves without metal components, and increase their thermal efficiency. Thanks for that. 
  I looked at a YouTube video where CFI was being used to make a pizza oven.  He raised a couple of safety issues concerning inhaling fine fibers: https://youtu.be/1Fl-Ut4b8K8?t=65  That suggests that if this material is used for cookstoves, there should be some concern about accidental exposure of stove users to fibers if the stove breaks apart with age. 
  Do you have any comments on safety issues? 
  Cheers, Julien.
