Gasifier Experimenters KitGasifier System ComponentsTechnical ResourcesGasification Worshop (June,08)Downdraft Gasifier SizingHere's some rough equivalencies, approximations andrules of thumb to understand downdraft gasifier gas flowneeds, HP equivalencies and reactor sizing. For engineapplicatons, I find it easier to size by actual HP needed,not by swept volume x RPM. Seldom is an engine runningat wide open throttle, as such calculations suggest.In general, size your gasifier for typical power needs, notthe rare max rates. If in doubt, err on the size of too smallto lessen tar risks from too low of temps.Here's how to approximate the relationships of liquidfuel to HP to KWe in your vehicle or genset:1 gal of gasoline or diesel produces about 15HPmechanical for one hour, or 10kwh electricity in a genset.How much HP is your vehicle using at cruise?60MPG = 1gal/hr or 15HP for one hour30MPG = 2gal/hr or 30HP for one hour15MPG = 4gal/hr or 60HP for one hourSolid biomass to syngas to power:http://www.allpowerlabs.org/gasification/resources/index.html (2 of 7) [10/9/2008 08:00:33]
