If the blast furnace heat is used to heat coal, then it needs to meet the conditions of coal combustion, coal combustion needs oxygen and suitable environment to achieve the appropriate combustion conditions. We need to understand these knowledge. Here is a description of the combustion conditions.
1:足够的氧气
1:Enough oxygen
为了使煤中的可燃成分完全燃烧并转化为CO2/SO2/H2O气体产物,必须保证充足的空气。没有氧气,煤就不能燃烧,所以必须保证热风炉的供气。热风炉配套设施中的透平风机满足这一条件,向炉内吹入大量的空气,为煤的燃烧提供大量的氧气。
Adequate air must be guaranteed in order to complete combustion of combustible components in coal and convert them into CO2/SO2/H2O gas products. Without oxygen, coal can not be burned, so the supply of hot blast stove must be guaranteed. The turbofan fan in the matching facilities of hot blast stove meets this requirement and injects a large amount of air into the furnace to provide a large amount of oxygen for coal combustion.
2:高温环境
2: High temperature environment
高温可以显著提高煤的燃烧性能,有利于加速燃烧反应和点火稳定性,减少化学和机械的不完全燃烧损失,除了煤只达到规定的燃点外,还有可能发生燃烧。热风炉炉顶和燃烧室的设计遵循防热原理。
High temperature can significantly improve the combustion performance of coal, accelerate combustion reaction and ignition stability, reduce chemical and mechanical incomplete combustion loss, besides coal only reaches the prescribed ignition point, there may be combustion. The design of the top and combustion chamber of the hot blast stove follows the principle of heat protection.


3:燃烧器与空气混合
3: Combustor and air mixing
为了确保煤炭燃料和空气可以混合充分,与他们保持良好的联系,可以通过减少煤的粒径,增加煤反应表面积,燃烧压力,调整气流运动和其他方面,可以配备煤粉设备、煤炭更小的微粒的形式进入燃烧室,时刻可以充分燃烧,更,节能!
In order to ensure that coal fuel and air can mix fully and keep good contact with them, we can enter the combustion chamber by reducing coal particle size, increasing coal reaction surface area, combustion pressure, adjusting airflow movement and other aspects, equipped with pulverized coal equipment and smaller particles of coal, which can be fully burned at all times, more efficient and energy-saving.
以上是对热风炉煤燃烧条件的介绍,相信您已经看过了以上的介绍也清楚的了解了吧,充足的氧气和高温环境是必不可少的燃烧条件,您可以在以后的实践操作中参考本文的内容。
Above is the introduction of coal combustion conditions in hot blast stove. I believe you have seen the above introduction and clearly understand it. Adequate oxygen and high temperature environment are indispensable combustion conditions. You can refer to the content of this article in future practice.
