为了深入认识近年发展起来的一种新型燃烧技术---高温空气燃烧的机理和超低氮氧化物排放特性，本文将扩散燃烧模型、热力NO生成模拟与完全湍流N-S方程相结合，数值研究了甲烷高温燃烧的火焰特性、空气预热温度对燃烧特性和NO排放浓度的影响规律。研究结果与实验数据符合良好，为在我国发展这项技术提供了依据。
The high temperature air combustion is the newest combustion technology developed in recent years. In order to better understand its mechanism and characteristics of super-low NOx emission level, a numerical simulation combined with the diffusion combustion model, thermal NO model and theturbulent N-S equation has been performed in this paper. Flame features and Influences of preheated air temperature on combustion process and NO emission have been investigated. The numerical results agree with measurement very well.This research provided fundamental date for developing the technology in China.
