Numerical Simulation of an Alternative Model of Biomass Fuel

Abstract

Biomass fuel oil is more and more widely used in industrial production. However, due to the complexity of aviation kerosene composition, the combustion mechanism of aviation kerosene is often simplified. In this paper, a simplified combustion model using n-heptane instead of biomass-fuel is proposed, and the model is studied by numerical simulation. After comparing the calculation results of the simplified model with that of the single step reaction, the influence of the chemical reaction on the combustion process of n-heptane and the combustion characteristics of the reaction at different ambient temperatures are obtained. The sensitivity of different components is different under different ambient temperature. High temperature will promote the formation of CO, C₂H₂ and other components, while low temperature will promote the formation of CO₂, C₂H₂ and other components. The influence of temperature on other components is relatively less obvious, such as C₃H₆. For the research of alternative fuels, we can better understand the combustion characteristics of biomass fuels in the combustion process, thus providing more theoretical support for the use of biomass fuels.
