摘要

为研究天然气掺氢后在家用燃气灶上的燃烧特性变化，将天然气掺氢燃烧技术应用于家用旋流式燃气灶上，进行数值模拟和热态实验。首先对详细燃烧机理GRI-Mech 3.0进行了简化，通过对比验证，简化机理与详细机理的计算误差小于1%。然后使用简化机理进行燃气灶的数值模拟，将数值模拟与热态实验计算结果进行对比分析，发现燃烧区域平均温度的最大误差不超过12%，证实了数值模拟的可行性。最后进行了天然气掺氢工况的数值模拟，结果表明家用燃气灶的一次空气系数随着掺氢体积分数的提高逐渐上升，对燃烧特性影响较大。同时，掺入体积分数15%的氢气后，CO排放的摩尔分数降低了约9%；燃烧区域平均温度基本保持稳定，证实了天然气掺氢技术的有效性。研究成果为天然气掺氢燃烧技术在燃气灶上的推广应用提供参考。

Abstract

In order to study the changes of combustion characteristics of domestic gas stoves after mixing natural gas with hydrogen

numerical simulation and thermal experiment research are carried out on the application of natural gas hydrogen-mixing combustion technology in household swirl gas stoves. First

the detailed mechanism GRI-Mech 3.0 is simplified. Through comparison and verification

the error between the simplified mechanism and the original mechanism is less than 1%. Secondly

using simplified mechanism for numerical simulation of pure methane gas stove

the numerical simulation and thermal experimental calculation results are compared and verified. It is found that the maximum error of the average temperature of the combustion zone does not exceed 12%

which confirms the feasibility of the simulation. Finally

a numerical simulation study of methane hydrogen mixing conditions is carried out. The calculation results show that the primary air coefficient of domestic gas stoves gradually increases with the increase of the hydrogen mixing ratio

which has a great influence on the combustion characteristics. After adding 15% of the volume of hydrogen

CO emissions are reduced by about 9%; and the temperature remains basically stable

which confirms the effectiveness of methane hydrogenation technology. The research results have reference value for the popularization and application of natural gas mixed with hydrogen in the combustion of gas stoves.
