The gross calorific value (GCV) of dry bagasse has a mean value of 19605 kJ/kg. The gross calorific value (GCV) of wet bagasse is based on the composition of wet bagasse. Water has no calorific value and it also absorbs heat being vaporized during combustion. The combustion reactions of bagasse as a fuel are as given in Table 3 ( Mugadhi 1999 ...

We can thus take corrective action. Illustration: Consider a 10TPH, 10.5 Kg/cm2 boiler with feedwater temperature of 90degC and S: F ratio of 14. Then the efficiencies of the boiler with reference to GCV would be 80% and with NCV would be 89%. However remember in both cases the quantity of fuel required will be the same!
