Thanks for your input. The boiler supplies a closed loop radiant floor
Kytec pipe heat distribution system filled with food grade glychol. A
conveyor lifts wood waste into a hopper and three multistage augers
transfer the biomass chips into the furnace where the fuel is
concentrated and fans blow in air and the fire reaches high temperatures
heating the steel plates and water circulating pipes. It is inside the
boiler chamber (second stage of the furnace) that large logs are
converted to biochar when the air is shut off. I had not thought about
dunking it and given this set up currently this would be hot and
difficult. I am transitioning this property with the business to a
multistakeholder cooperative and I am looking for members. G

Precisely that is why I propose using the huge boiler in the greenhouse
to produce biochar and the waste heat is "captured" and utilized for
raising worms and growing food.
There's no technical problems with this as Alex has demonstrated with a
normal woodchip stoker boiler.
I would like input from experts who
want to advise and partner with this project. Nightime fire tending is
covered and when hot and air is shut down the char forms and the water
continues to circulate in the floor until light of day,
No need to the high mass masonry type stove using a TLUD that Ronal seems
to be advocating, go straight from sequentially fired batch loaded TLUD
into a stratified water thermal store, if the floor runs at low
temperature with an injector circuit the rejected heat in the water
returning at ~30C need not destratify the store.
char is cooled
and removed and cycle resumes with reignighting the fire box mid
afternoon. The char chunks produced in this huge wood biomass burner is
amazing and I have noticed positive results in both the worm beds and
gardens where it is applied. Gerrie
Why wait to cool the char, just dunk it to reduce the chance of a high CO
emitting continued combustion?
