Design of Bagasse Dryer to Recover Energy of Water Tube

Hawaii. Typically a mill wet bagasse contains 50% moisture with a gross calorific value of 2270 kcal/kg (˜1900 KJ/kg).[1] Normally bagasse is directly fed to the boiler to generate the steam and surplus bagasse is stored in bagasse yard. It is a well-known fact that calorific value of bagasse is decrease with increase in moisture of bagasse.

Air Fuel Ratio Effect on Combustion Efficiency

Oct 23, 2013 · Combustion efficiency is dependent upon using the right amount of air to consume the fuel. In fuel-fired process heating, the largest source of energy loss is through the exhaust stack, which is why managing air flow is essential to combustion efficiency. When fuel burns in the presence of oxygen it is converted to carbon dioxide, water and heat.

Emissions of NOx and SO2 from Coals of Various Ranks, Bagasse

Jun 01, 2011 · Results showed that in the case of four coals studied, NOx emissions in O2/CO2 environments were lower than those in O2/N2 environments by amounts that ranged from 19 to 43% at the same oxygen concentration. In the case of bagasse and coal/bagasse blends, the corresponding NOx reductions ranged from 22 to 39%.
