secondary combustion air

基本解释

The experimental results indicate that secondary air can accelerate volatile combustion in dilute phase zone and raise the temperature remarkably.
试验结果表明：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；
These sediments are prone to spontaneous combustion, which is known as the secondary combustion air 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 use of coal distributing air, secondary air supported combustion in free board and some other methods are proposed as the improvement measures together with their design and operating data.
提出了改善措施，如采用播煤风，采用二次风强化悬浮段燃烧。并给出了设计和运行的参数值。
