1.2 CHARACTERISTICS OF DIFFERENT BIOMASS FUELS<br />

Figures 1-4 and 1-5 show the chemical composition and heat<strong>in</strong>g values for<br />

different types of biom<strong>as</strong>s which can be used <strong>as</strong> fuel <strong>in</strong> boilers. Comput<strong>in</strong>g<br />

heat<strong>in</strong>g efficiency accurately requires calculat<strong>in</strong>g both the composition of<br />

biom<strong>as</strong>s and the thermal efficiency of the boiler, us<strong>in</strong>g direct <strong>as</strong> well <strong>as</strong> <strong>in</strong>direct<br />

methods.
