Well that negates current usage, which includes stoves as heating 
devices. Stove is usually qualified by Wood and cook in conventional usage.
Gasifier to my mind is a distraction, since gasification is a critical 
part of all combustion, but if the primary output of a stove is burnable 
gas, then it should be a gasifier stove.

How  many variables characterise a stove ?
Fuel,
Fuel size,
Combustion zone
Combustion chamber material
Primary air
Secondary air
Primary output useage.

My first 7, which critically define a stove.

We seem to have gone mad on taxonomy in the last few weeks, its being 
driving biologists mad for centuries too.
