Thermal power plants rely heavily on coal as their primary fuel source. Coal handling involves transporting coal from mines to the plant via waterways, rail, road, ropeways or pipelines. At the plant, coal is unloaded and stored either outdoors in piles or heaps, underwater, or in live storage bunkers. Effective coal storage aims to prevent ...
Coal Handling Pump Problems. Two key factors cause problems when handling coal. First, coal sinks in water. Second, water collects in low spots. Combine this with a conveyor system, which operates below ground and has dust, fine particles and chunks falling from the belt. With nowhere to drain, water collects, and whatever is with it …
A flowchart is a visual representation of the sequence of steps and decisions needed to perform a process. Each step in the sequence is noted within a diagram shape. Steps are linked by connecting lines and directional arrows. This allows anyone to view the flowchart and logically follow the process from beginning to end.
The main sub-systems of the coal handling plant are wagon tipplers, Belt conveyors, Coal Crushers, and drive units. The coal is received by railways or large trucks from mines. Two types of wagons are used on the Railway i.e. BOXN wagon and BOBR wagon. In the case of a BOXN wagon, the material is discharged from the top. ... 39 …
Therefore, one of the major requirement of a power plant is to reduce the cost of handling of coal from the point of its origin upto the furnace of boiler where it is burnt. Various steps involved in a coal handling system as shown in Figure A are : Coal delivery. Unloading. Preparation of coal. Transfer of coal. Storage.

Coal has a wide range of moisture (2-40%), sulfur (0.2-8%), and ash content (5-40%). These can affect the value of the coal as a fuel and cause environmental problems in its use. The depth, thickness, and configuration of the coal seams determine the mode of extraction. Shallow, flat coal deposits are mined by surface processes, which are ...
