Abstract

In this study, bamboo and coal co-gasification is carried out in a downdraft gasifier at different blending ratios. The study mainly focuses on the flame front propagation rate (FFPR), bed movement, effective front propagation, tar concentration and particulate concentration in the producer gas. Three different air mass fluxes namely \(\varPhi 1\), \(\varPhi 2\), \(\varPhi 3\) were used to perform the gasification process. The experimental results show that flame front propagation increases upto 10 wt.% coal, after which it starts decreasing for further increase of coal percentages in the feedstock for all air mass fluxes. Rate of bed movement also shows the similar trend as flame front propagation except at \(\varPhi 3\). The effective propagation rate increases upto 10–20 wt.% coal beyond which the increment is insignificant for all air mass fluxes. In all air mass fluxes, the tar concentration decreases while the concentration of particulate increases by increasing coal percentages in the feedstock.
