Hi guys, thod l make life easyer for new beginers in gasification wondering how big their gasifiers shuld be.
I spent hours and numerous sheets of paper calculating this things out when designing gasifiers. Imbert charts are one option but what if you need to size a different style gasifier? Flute? Simple fire? Even WK?
So, what l always did was take measurments from guys here that built good performing gasifiers, take their and mine engine size in to acount and try to proportion them.
The other day l was dusting my gasifier measurment memory department in the brain, compareing my sucsessfull builds and their sizes, and what l found was kinda groundbreaking for me, simplicity wise.
In most my gasifiers, the volume of active charcoal fits preety close to engine size! Talking about actual gasifier active volume, the volume taken by actual glowing charcoal. All insulations and ashcones taken away.
In real world this means a 2,5l engine will need about 2.5l of active charcoal in the hearth, that is calculated under the nozzles only. Preety easy now with online frustom andpiramid calculators to fit your engine.
Hope this is helpfull. Its not precise but shuld get you in the ballpark
