【摘要】 虽然蓄热燃烧技术已经在加热炉上广泛应用,但NO_x生成机理还不很清楚。本文以鞍山热能研究院建造的蓄热式加热炉为原型,对低热值煤气蓄热燃烧过程进行了数值模拟。比较了不同预热温度、不同空气系数、不同空气喷口倾角和不同煤气和空气喷口间距对低热值煤气燃烧过程生成NO_x的影响。数值模拟研究的结果作为蓄热式加热炉设计参考。更多还原

【Abstract】 Although regenerative combustion is widely used in Heating furnace,it is not clearly about the NO,formation mechanism in regenerative combustion.The processes of HTAC for low heat value gas for an heating furnace built Anshan Research Institute of Thermo-Energy are numerically simulated.We compared the effect of combustion air and gas preheat temperatuer,air coefficient,the inclination between jets and the distance between air jet and gas jet on the combustion process.The results of numerical simulation can provide references for the design and development of regenerative combustion heating furnaces.更多还原
