Seems ALL gasifiers have at least some refractory. But I see a trend and am curious what each of you with different brands sees.
Forced down draft styles seem to have full refractory in the secondary CC. In the primary though, it seems they have refractory only in the bottom and 1/3 or less up the sides.
RMND units (Seaton, GreenWood,Greenfire,Adobe, etc) have the primary CC completely refractory. I would describe the secondaty CC as part refractory (back wall of primary CC) and part insulation over steel.
Assuming I am correct above, my observation is that
1)Creosote does NOT stick to refractory. It does seem to stick to the primary CC where the steel is exposed. Not knowing much about those styles, is there water behind the steel there?
2)Forced down draft styles like the CB eClassic started out with refractory, but users have found the need to remove the refractory. Why, and how has it helped?
