Perhaps you would be kind enough to put us out of our semantic misery, and 
provide a clear and definitive definition of what constitutes a gasifier, 
and whether a TLUD can be correctly defined as a  "close coupled gasifier 
stove", or if perhaps it should more correctly be termed a "fan assisted 
stove ." :-)

Hydroxylated combustion is an interesting phenomenon. This phenomenon is 
probably what would explain the beneficial results attained with steam 
injection.
