High heating value hhv
Webbetween ash and extractive content with the higher heating value. Moisture in biomass generally decreases its heating value. Ash and extractive content are two important parameters directly affecting the heating value. High ash content of a plant part makes it less desirable as fuel, whereas high extractive content adds to its desirability.
