Camp wood stove 柴火爐 and rocket stove 火箭爐, TLUD, biomass cooker

It's getting trendy, but how good is it?

Caloric values of different fuels: Engineeringtoolbox 

Coal is ~ 2 times more efficient than dry wood, propane is 3~ times per weight

For smoke, wood has the most, if used simple open air

So for such kind of stove above, it's good for warming, rather than for cooking, or boiling water?

Many portable or camp "rocket stove" on market are merely stripped down version of household rocket mass heater: 

with a J tube(burning chamber + heat riser), 

- air intake duct may be skipped

- most without secondary combustion

- weak or no venturi effect

Recommended portable/camping wood stove:

Improved stove from bioenergylists, eg, TLUD gasifier , ~4000BTU/h

aprovecho on TLUD, low PM2.5 stove 

Peko Pe, aka original TLUD, OSTI research on PM2.5

with Concentrator disc, aka champion TLUD

Solo stove and similar ones. DIY a la solo stove/ gasifier
 

MimiMoto (2016) , forced draft TLUD, aka FD TLUD, wood pellets optimsed,  tier 4  plus emission, 3 sizes of combustion chamber, with higher turn down ratio (for simmering). ETHOS, ETHOS 2014

Tier 4 emission vs affordability

SupaMoto:, based on MiniMoto, plus IoT

Btw, Solo (2011) or Hobo stove is a TLUD, but with weak effective secondary combustion design(under 15 in diameter), venturi / chimney effect( if 12 in height or more), and no turn down ratio control. Time will tell

Maybe this is why many YouTubers  2  3 do not understand wood gas, or gasifiers( eg fuel overfilled), do not compare eg with objective water boil test,   find TLUDs unattractive. This isn't doing justice to TLUDs

Biolite campstove 2, FD TLUD, or semi gasifier , >4000BTU/h( assume 50% eff)

徐雲小號claim >8500BTU/h，but no emission data， 2
