A smoke chamber has been used to measure the smoke generated from seven different biomass fuels. These fuels are wood, peanut shells, cardboard, chipboard, straw, hay and eucalyptus leaves. This equipment allows a direct comparison of the smoke generated between these seven biomass fuels. A sample of each fuel was exposed to a radiant heat source and the amount of smoke measured with time. Analysis of the results showed that fuels such as straw or hay produced high levels of smoke quickly for a given mass loss. More compact (higher density) fuels took much longer to produce the same amount of smoke illustrating the benefit of producing fuel briquettes. This technique could also be used to measure the smoke generated as the composition of the fuel briquette was varied.
