Characteristics of Biomass as a Heating Fuel

As a result, the energy content of a biomass fuel should be thought of as a range rather than a fixed value. Figure 1 shows the typical range of some common fuels. The most important noticeable trend in these data is that wood (which has a lower ash content) tends to have a slightly higher heat value than field crops. Figure 1.
