[Stoves] Accidental TLUD technique discovery

[Paul Anderson]

Neil, Todd, Crispin and all,

1.  The cone to aid ignition gives increased draft and keeps the heat 
together.  A Kelly kettle (mentioned) could be used for its cone shape 
AND it can be for heating water.   Great double duty.

2.  Fire ignition material in TLUD includes some pieces of charcoal that 
has had some appropriate liquid such as lamp oil or kerosene (or melted 
candle???) on it.  The igh poreosity of the charcoal lets the starter 
liquid get further inside than with wood, (and pellets are so dense the 
starter fluid mainly coats the smooth outer surface.
