Here, the coal feeds into the furnace at the four corners of the furnace. This produces a cyclonic effect in the furnace, ensuring a proper mixing of air and fuel that is essential for proper combustion. Due to this effect, a fireball is created with the burners firing tangential to it. The combustion air also enters into the furnace ...

Monitoring and diagnosis of coal mill systems are critical to the security operation of power plants. The traditional datadriven fault diagnosis methods often result in low fault recognition rate or even misjudgment due to the imbalance between fault data samples and normal data samples. In order to obtain massive fault sample data effectively, based on the analysis of primary air system ...

The pulverizers and burners system provides pulverized coal to the boiler as primary fuel. Coal enters the plant from the coal handling system where it has been crushed to consistent sizes where it can be handled by the pulverizers. It is delivered to the coal bunkers which are located directly above their respective pulverizers, also called mills.
