Paul, I still haven't seen rice hulls in a stove, it is apparent they have unique combustion characteristics. I was just mentioning ignition using electric elements with blown air, we use these to ignite wood chip stokers and pellet stoves/boilers. The thing is that these produce hot air that then pyrolyses the wood, this produces offgas and char, the char then ignites and gets hot enough to ignite the offgas and then a flame develops. Until the flame takes hold the offgas is vented and is very acrid. I think there has to be a flame present early in the ignition to burn the offgas. BTW if anyone in UK wants some bits and pieces from pellet stoves to play with then I have 2 redundant 15 and 25kW devices which were removed from unsuccessful installations.
