Spray combustion properties of fast pyrolysis bio-oil produced from rice husk

The research presented here is focused primarily on spray combustion of pure fast pyrolysis bio-oil from rice husk. A combustion systems is developed to attain a possibility of firing of the bio-oil in a routine way. The start-up and shut down combustion procedures is established. The bio-oil is properly pretreated and spray combustion properties of pure fast pyrolysis bio-oil are studied. After 40 min combustion become steady and the temperature in the center of the combustion chamber is above 1400 degrees C. The CO concentration decreases with ER, and below a certain ER, the CO level exponentially increases. The measured NO(x) concentrations slightly increase at higher ER. Low values of SO(x) emissions are measured, and as expected these values are very low (<30 ppm). The O(2) concentration increases with ER. Bio-oil has the potential to replace diesel and gas for on-site power generation and heating, to be a fuel source for large-scale combustion systems such as furnaces, boilers and gas turbines.
