Description
Screen coal refers to coal that has been processed through a screening process to remove impurities and ensure a uniform size. The screening process involves passing the coal through screens with various sized openings to separate it into different size fractions.
Screen coal is typically classified into different sizes based on the diameter of the coal particles. The different size fractions of screen coal have different properties and are used for different purposes. For example, larger size fractions are often used for industrial applications, while smaller size fractions are used for residential heating.
Some common uses of screen coal include:
- Power Generation: Screen coal is used as a fuel for power generation in coal-fired power plants. The uniform size of screen coal ensures consistent combustion and efficient energy production.
- Steel Production: Screen coal is used as a fuel and reducing agent in the production of steel. It is often used in blast furnaces to help convert iron ore into molten iron.
- Heating: Screen coal is used for residential heating and cooking in areas where it is readily available. The uniform size of screen coal makes it suitable for use in stoves and furnaces.
- Industrial Applications: Screen coal is used in various industrial applications, such as cement production, brick kilns, and paper mills. It is used as a fuel and as a source of heat in these processes.
