Gasifier Experimenters Kit

Biomass Energy Foundation: Biomassof biomass, and adjusting to the correct air fuel ratio hasgiven us incredibly clean cars in the last 20 years. Thisdiagram shows the air-fuel ratios for pyrolysis,gasification and combustion of biomass.This website is devotedprimarily to biomassgasification, the primarybusiness and pleasure of TomReed over the last 3 decades.However, all combustion andgasification processes mustpass through pyrolysis at lowtemperature, so there is a lotof information here aboutpyrolysis and combustion aswell.Biomass fuels arecharacterized by what is calledthe "Proximate and Ultimateanalyses". They can be burneddirectly for heat or to makesteam for power. The"proximate" analysis givesmoisture content, volatilecontent (when heated to 950C), the free carbon remainingat that point, the ash (mineral)in the sample and the highheating value (HHV) based onthe complete combustion ofthe sample to carbon dioxideand liquid water.
