摘要
在天然气催化燃烧理论基础上进行了一些实践应用.在蜂窝状独石燃烧器和滞止点流动反应器(SPFR)中研究了在稳态条件下甲烷和空气的贫燃料混合物燃烧的污染排放特性.研究表明只有当催化表面温度显著高于普通燃烧的点燃温度时,气相燃料和空气混合物才会被点燃.既然催化反应延伸到了清洁和稳定氧化条件持续的范围,催化反应抑制了气相燃烧是合适的.利用天然气催化燃烧炉作为热源来烘烤食品,同时与普通电烤箱做了一些比较,实验结果为催化燃烧烤箱所烧烤出的食品在嗅觉和味觉上较好.
The applications of nature gas in a catalytic combustion oven is discussed in the article according to its theory. The emissions characteristics of the combustion of fuel-lean mixtures of methane and air were studied in steady-state conditions in a honeycomb monolith burner and a stagnation point flow reactor （SPFR）. The investigation showed that the gas-phase fuel/air mixture does not ignite until the catalytic surface is significantly above the ordinary auto-ignition temperature. This inhibition of gas-phase combustion by the catalytic reactions is desirable, since it extends the range over which clean and stable oxidation conditions persist. The catalytic combustion burner was used for roasted food. The result of experiment showed that the sense of smell and taste for the roasted food by catalytic combustion oven was better than that of conventional electrical oven.
