摘要

稀释燃烧可以实现高效低污染燃烧

从化学反应动力学的角度探究N

和CO

稀释气体对生物质气层流燃烧速度的影响。通过调整反应机理

设定虚拟稀释气体N

、CO

向一定成分的CH

/CO/H

混合气分别添加体积分数为0%~60%的2种稀释气体或其虚拟气体

基于此

对影响其层流燃烧速度的各效应(稀释效应、热效应、直接反应效应、三体反应效应)进行解耦

分析了预热温度、压强、当量比对各效应占比变化的影响。同时

探究了活性自由基(H/OH)最大浓度与层流燃烧速度的关系

结果表明二者成正比关系

并且较高当量比时拟合效果最好

而温度和压力对其拟合效果的影响较小。

Abstract

Dilution combustion enables high efficiency combustion with low pollution. The effects of N

and CO

as diluents on the laminar burning velocity (LBV) of biomass-derived CH

/CO/H

syngas were explored from a chemical-kinetic perspective. The reaction mechanism of syngas combustion was modified to set up virtual N

and CO

diluents

allowing the individual effects on the LBV

namely

the dilution

thermal

direct reaction and three-body reaction effects

to be decoupled. The variation of contributions from the four effects with pre-heat temperature

pressure and equivalence ratio were analyzed from numerical simulations

with each real or virtual diluents added at 0%-60% (volume fraction) to the mixture. In addition

the relationship between the peak concentrations of active radicals (H/OH) and the LBV was examined. A linear correlation is observed with the best fit obtained at higher equivalence ratios

whereas temperature and pressure exert only minor influence on the fit quality.
