Carbon monoxide burning is a shift reaction correctly displayed like this: O2 + 2CO ←→ 2CO2 so it is inposible for all the CO to react. The reaction is depended on the conditions like presure and temperature.
I'm guessing this is why you don't see any charcoal gasifiers being manufactured or sold by big companies. As simple as it is to understand the importance of good ventilation, you know that if enough people adopted this technology, a few would end up dying of CO poisoning. The liability would be too high.
CoryW,ouch...isn't the gas the same as in an wood gasifier ?
Kristijan,for complete combustion, stoichiometric, 1Kg CO + 0,57Kg O2 = 1,57 Kg CO2normal full combustion is adviced to use 120% of the air needed...
Thierry,Correct, using one defined measuring point for the TC and use it with a PID to control a solenoid to keep the core temperature within the desired levels.Solenoid for endothermic materials as exhaust gasses or water vapor.
Yes. Wasn't meant to be a jab at gasification, Just reality
Nothing's perfect. If cars ran perfectly there'd be no CO in the exhaust. Same for woodgas... a little bit goes right through the motor without burning. Better tune up = less CO emissions.
the solenoid valve operates in all or nothing (open 100% or 100% closed)?
Hi Thierry,Yes in this test setup it does, but with some tricks of course Having a minimum pipe and a maximum restriction, the solenoid never closes the minimum (hand valve on secondary pipe )Imagination is the only restriction in life
You are absolutley right Koen but eaven with 120% of oxigen it is not posible to burn absolutley every molecule of CO becouse every chemical reaction has a diferent reaction rate coeffitient. That tells the amount of reactants that will actualy react to form products. Unfortunaly l cant find my old textbook with the table of reaction rate coeffitients for most usual reactions. They are usualy guite high meaning most (lets say 99,5% or more) of reactants will actualy convert to products but with a poisonous substance the 0.5% can not be neglected.
Hi Kristijan,That is exactly why woodgas is to prefer above gasoline... Less reactants in the fuel (read producer gas ), much cleaner emissions... lets keep it that way... clean and green...
yup, i am learning how to weld the bigger things ...
and she's happy with it
Ow yeah, this one is for a huge distill / cooking set (booze) , to provide the heat for the cooking
Welding it on the chassis, next the small one, learning by doing...
looking good I see nasa calling
replacement for the spaceshuttle program... Launched by charcoal Hydrogen
Can I pull the rocket out with my charcoal tractor..?
Setting up a new alternative space program, everything with charcoal...Even charcoal dust in a geostationary orbit, to block the sun radiation, preventing the heating up of our atmosphere Only our imagination is the limit ... in our dreams
reminder to myself... don't forget to install the safety lid... or walking on the moon is eminent...
Koen; One thing that jumped right out at me with this build is, 3 legs might work better than 4. You know that old saying that 3 points determine a plane. The 4th leg might make it harder to sit steady on a floor. TomC
Good point Tom, I build 3 legged log tables because they stand on uneven surfaces much better. Oh yea it is way easier too.
