利用高温预热空气，结合内部气体的强循环，可以形成与诸如扩散火焰与预混火焰等传统火焰完全不同的火焰类型。在高于800℃温度和空气中低于15％氧气条件下所获得的火焰特性包括：炉内均匀温度分布、低NOx生成和低噪音。这种燃烧叫高温室气燃烧HTAC（HighTemperatureAirCombustion），目前，在日本受到空前重视，被认为是节能、减少污染物排放和缩小炉子尺寸的一项革命性的技术。在改进炉膛性能方面的这些显著优点可应用于多种火焰加热系统，包括燃气透平系统、锅炉、工业炉和住宅加热装置。
Preheating the air at high temperatures, combined with the strong circulation of internal gas, creates a completely different type of flame than traditional flames, such as diffusion flames and premixed flames. Flame characteristics obtained at temperatures above 800 ° C and below 15% oxygen in air include a uniform furnace temperature profile, low NO x generation and low noise. This type of combustion is called HTAC (High Temperature Chamber Combustion). At present, it has received unprecedented attention in Japan and is considered as a revolutionary technique for saving energy, reducing pollutant emissions and reducing furnace size. These significant advantages in improving furnace performance can be applied to a wide range of flame heating systems, including gas turbine systems, boilers, industrial furnaces, and residential heating units.
