Coal Crushing and Screening Plant

A coal crushing and screening plant is an essential part of a thermal power plant that is used to crush and screen the coal before it is fed into the boilers. The process of crushing and screening the coal involves several stages, including primary crushing, secondary crushing, and screening. In this blog post, we will discuss the coal crushing and screening process in detail.

Primary Crushing:

The primary crushing process involves breaking down the raw coal into small pieces using a jaw crusher. The jaw crusher reduces the size of the coal to a manageable level and is the first stage in the crushing process.

Secondary Crushing:

Once the coal has been reduced in size, it is fed into a secondary crusher, which further reduces the size of the coal to a more manageable level. The secondary crusher can be a cone crusher or an impact crusher, depending on the size of the coal and the desired output.

Screening:

After the coal has been crushed to the desired size, it is screened to remove any impurities and ensure that the coal is of the correct size for the combustion process. The screening process involves passing the coal through a series of screens of varying sizes. The screens are designed to remove any oversized or undersized coal and ensure that the coal is of the correct size for use in the boilers.

Storage:

Once the coal has been crushed and screened, it is stored in a storage yard until it is required for use in the combustion process. The storage yard is typically located near the boilers, and the coal is transported to the boilers using conveyor belts.

Conclusion:

The coal crushing and screening process is an essential part of a thermal power plant, ensuring that the coal is of the correct size and free from any impurities before it is fed into the boilers. The process involves primary crushing, secondary crushing, screening, and storage. Proper maintenance and operation of the equipment used in the coal crushing and screening process are essential to ensure the safe and efficient operation of a thermal power plant.

Coal Handling Plant Operation

A coal handling plant (CHP) is a critical component of a thermal power plant, responsible for receiving, storing, and transporting coal for use in the combustion process. The operation of a CHP involves several processes, including coal unloading, stacking, reclaiming, conveying, crushing, and ash handling. In this blog post, we will discuss the operation of a coal handling plant in detail.

Coal Unloading:

The first step in the operation of a CHP is the unloading of coal from the incoming trucks or wagons. The coal is unloaded using cranes or conveyors and transported to the storage yard.

Coal Stacking:

Once the coal is unloaded, it is stacked in a predetermined pattern in the storage yard using a stacker. The stacking process ensures that the coal is stored efficiently and can be easily reclaimed when required.

Coal Reclaiming:

When the coal is required for use in the combustion process, it is reclaimed from the storage yard using a reclaimer. The reclaimer is designed to reclaim the coal in a predetermined pattern, ensuring that the coal is of the correct size for the combustion process.

Coal Conveying:

Once the coal is reclaimed, it is transported to the boilers using conveyor belts. The conveyor system consists of several belts that are interconnected to form a loop. The conveyor belts are designed to transport the coal efficiently and minimize the risk of spills or blockages.

Coal Crushing:

Before the coal is fed into the boilers, it is crushed into smaller pieces using coal crushers. The crushers are designed to break down the coal into smaller pieces, making it easier to handle and transport.

Ash Handling:

When the coal is burned in the boilers, it produces ash. The ash is collected using ash handling systems and transported to an ash storage facility for disposal. The ash handling system can be either a dry or wet system, depending on the design of the power plant.

Maintenance:

Proper maintenance is essential to ensure the safe and efficient operation of a CHP. The maintenance of the equipment used in a CHP includes regular inspection, lubrication, and cleaning. Any issues or defects in the equipment should be addressed immediately to prevent any damage or downtime.

Conclusion: The operation of a coal handling plant involves several processes, including coal unloading, stacking, reclaiming, conveying, crushing, and ash handling. Proper maintenance and operation of the equipment used in a CHP are essential to ensure the safe and efficient operation of a thermal power plant.

Vibrating Screens: Vibrating screens are used to separate the coal into different sizes. The screens are designed to remove any impurities and ensure that the coal is of the correct size for the combustion process.

Stacker and Reclaimer: The stacker and reclaimer are used to stack and reclaim the coal in the storage yard. The stacker is used to stack the coal in a predetermined pattern, while the reclaimer is used to reclaim the coal from the stack.

Dust Suppression System: The coal handling process generates a considerable amount of dust, which can be hazardous to the plant's safety and efficiency. Dust suppression systems are used to control and reduce the amount of dust in the plant. These systems typically use water or chemicals to suppress the dust.

Ash Handling System: When the coal is burned in the boilers, it produces ash. Ash handling systems are used to collect and dispose of the ash. The ash can be collected in dry form using electrostatic precipitators or in wet form using scrubbers. The collected ash is typically transported to an ash storage facility for disposal.

Coal Sampling Unit: The coal sampling unit is used to sample the coal and determine its quality. The unit is typically located in the coal conveyor system and can sample the coal in real-time.

Conclusion:

The equipment used in a coal handling plant plays a crucial role in the efficiency, safety, and overall performance of a thermal power plant. The equipment includes coal crushers, conveyor belts, vibrating screens, stacker, and reclaimer, dust suppression system, ash handling system, and coal sampling unit. Proper maintenance and operation of these equipment are essential to ensure the safe and efficient operation of a coal handling plant.
