絕熱火焰溫度數值模擬分析

Numerical Simulation and Analysis of Adiabatic Flame Temperature

摘要


本研究旨在探討高溫爐內反應產生的溫度,並模擬不同氣體和粉煤的燃燒情況。我們使用Excel中的VBA撰寫程式,運用能量守恆原則和熱力學第一定律的絕熱火焰溫度公式,通過計算出口焓總值等於入口焓總值時的絕熱火焰溫度來推導最高溫度。本研究確認了焦爐氣(COG)、噴吹煤(PCI)和其他氣體的參數,並列出燃燒方程式,以遵循質量守恆定律。最後,我們使用牛頓法計算理論絕熱火焰溫度。

This study aims to investigate the highest temperature generated by the reaction in the high-temperature furnace and simulate the combustion of different gases and pulverized coal. We developed a program using the energy conservation principle and the adiabatic flame temperature formula of the first law of thermodynamics, utilizing VBA in Excel, to derive the highest temperature by calculating the adiabatic flame temperature at which the total outlet enthalpy equals the total inlet enthalpy. The study confirms the parameters of coke oven gas (COG), pulverized coal injection (PCI), and other gases, and lists the combustion equations to follow the law of conservation of mass. Finally, we used the Newton-Raphson method to calculate the theoretical adiabatic flame temperature.
