Effect of methanol injection on the combustion performance of the main combustor
In order to explore the effect of methanol aqueous solution injection on the combustion performance of the aero gas turbine main combustor,the inlet conditions of the combustor after injection of different methanol aqueous solutions were calculated by iterative theory,and then the influence of different methanol aqueous solution parameters on the combustion performance of the aero gas turbine main combustor was numerically calculated by FLUENT software.The results show that the injection of methanol aqueous solution will reduce the overall combustion temperature,and with the increase of methanol substitution rate and water content,the maximum combustion temperature,average outlet temperature,and combustion efficiency in the combustor will gradually decrease,and the NO emission will be significantly reduced.Because the total calorific value of methanol and aviation kerosene is guaranteed to be equal,the overall difference between the temperature rise of the main combustor is small.
