These sediments are prone to spontaneous combustion, which is known as the secondarycombustionair preheater. The need for air preheater's hot spot detection to prevent them is necessary.
这些沉积物很容易发生自燃，称为空气预热器的二次燃烧，需要对空气预热器进行热点检测来加以预防。

The experimental results indicate that secondaryair can accelerate volatile combustion in dilute phase zone and raise temperature here remarkably.
实验结果表明：二次风可以促进挥发分在稀相区的燃烧，对提升稀相区的温度作用明显；

Using numerical simulation software, the paper analysis the influence of secondaryair to the pollutant discharged in high temperature and low oxygen air combustion.
