Proximate analysis is important in evaluating the combustion properties of waste or waste derived fuel. The fractions of greatest interest are: moisture content, ash, volatile matter and fixed carbon. Moisture adds weight to the waste fuel without increasing its heating value and the evaporation of water reduces the heat released from the fuel.
