Abstract. Continuous variations in coal quality have a strong influence on operation of thermal power plants. However, in absence of realtime measurements of quality, the operators remain partially blind to the actual coal being consumed, leading to suboptimal operation. A twostage solution is proposed for realtime soft sensing of coal type.
The coal mill grinding system is an important part of the dry process cement manufacturing. In cement plants, we usually adopt the air swept coal mill system or vertical mill system as the pulverized coal preparation system, which is arranged at the cement kiln head or kiln tail to provide fuel for clinker calcination. However, due to the flammable and explosive characteristics of pulverized ...

Background: Though the introduction of modern safer underground coal mining methods and automation, mine accidents still cause loss of lives, time, and money. This paper aims to analyze in detail the causes of safety and environmental issues in the coal mining industry, as well as the impact of IoT on coal : A systematic review was conducted. A comprehensive search involving Web ...
In the coal industry, there were also at least six strikes against safety measures (five to oppose a new safety lamp, and one to allow smoking in the coal mine during lunch). (Aldrich p. 90) When safety measures were introduced, workers had to be encouraged, trained, coaxed, and propagandized to use them. They often resisted new measures at first.
More OM News. Optimized coal pulverizer performance is a prerequisite for furnace combustion efficacy. Here are some solutions for overcoming common combustion problems.

3. Measures taken for improvement of safety in 2020 CIL has pursued several measures in the year 2021 along with the ongoing safety related initiatives, apart from compliance of statutory requirements for enhancing safety standard in mines of CIL and its Subsidiaries, which are given below: i. Conducting Safety Audit: Safety Audit for FY
The coal vertical mill adopts the temperature detection device the online gas analyzer and other explosionproof measures to ensure the safe operation of the equipment. An explosion proof valve is arranged on the upper shell to prevent the explosion of the pulverized coal in the mill and ensure the safe use of the equipment.
VG: At best, coal mill safety is not well understood and, at worst, it is ignored. When it comes to coal mill systems, most cement plant operators just presume that the supplier of the equipment knows all of the standards and rules and is capable of making a system that conforms to these and is therefore safe. However, this is not the case.
Today, coal mines follow rigorous safety procedures, high standards for health and safety, and also make sure that each worker receives proper education and training. These, among various other steps, have helped in making significant improvements in the safety of underground and opencast mining. Besides, the World Coal Association (WCA), which ...
All air and material goes to a form of intermediate storage like a bag filter, and from the bag filter it mechanically or pneumatically goes to a silo, where it will be fed to the burners. He said that in recent cases like the September 29 boiler explosion in India, a direct coalfired system was likely being used to generate power for the plant.
