摘要

合成气火焰传播规律的研究对燃气轮机的有效利用具有重要意义。本文研究了合成气(H2:CO = 2:8)在半封闭矩形风管中预混合富氧燃烧(Ω值:0.21,0.27,0.32,0.37)在高温(T值:300 K, 400 K, 500 K)下的火焰传播,并从灵敏度分析和动力学分析两方面评价了初始温度和富氧系数对LBV的影响。本文首次提出了膨胀效应对层流燃烧速度的影响,并采用一种新的方法分离了膨胀效应对层流燃烧速度的影响。研究表明,随着初始温度的升高,火焰前缘速度的指数增长阶段越快,缓慢增长阶段越慢。最大火焰锋面速度越小越早,平均火焰速度越慢。随着富氧系数的增大,火焰锋面速度峰值逐渐减小。富氧燃烧和初始温度的升高抑制了火焰在半开管内的传播,但促进了层流燃烧速度,增加了关键化学键和绝热火焰温度。净反应速率表明富氧燃烧主要促进H2 (R2)的燃烧反应。而提高初始温度主要促进CO (R29)的氧化。反应路径分析表明,富氧燃烧和初始温度的升高促进了H2和CO关键化学键的反应,提高了OH浓度,抑制了OH裂解反应。

Abstract

The investigation of syngas flame propagation has great benefits for the effective use of gas turbines. This essay sets out to study the flame propagation of premixed oxygen-rich combustion (oxygen enrichment coefficient in volume Ω: 0.21, 0.27, 0.32, 0.37) of syngas (H2:CO=2:8) in half-closed rectangular ducts at elevated temperatures (T: 300 K, 400 K, 500 K) and evaluate the effects of initial temperature and oxygen enrichment coefficient on the LBV from sensitivity analysis and kinetic analysis. This paper presents the effect of the expansion effect on laminar burning velocity for the first time, and separates the effect of the expansion effect on laminar burning velocity by a new method. Research shows that as the initial temperature goes up, the faster the exponential growth phase of the flame front velocity, the slower the slow growth phase. The smaller and earlier the maximum flame front velocity arrives, the slower the average flame speed is. As the oxygen enrichment coefficient goes up, the peak value of the flame front velocity gradually decreases. Oxygen-rich combustion and increasing initial temperature inhibit flame propagation in a half-open tube, but promote laminar burning velocity, which increases the key chemical bond and adiabatic flame temperature. The net reaction rate shows that oxygen-rich combustion mainly promotes the combustion reaction of H2(R2). However, increasing the initial temperature mainly promoted the oxidation of CO(R29). Analysis of the reaction path showed that oxygen-rich combustion and increased initial temperature promoted the reaction of H2 and CO with key chemical bonds, increased OH concentration, and inhibited OH cracking reaction.
