Coal and Coke Making Process an overview
Introduction : Coal is a fossil fuel formed from the remains of plants that lived millions of years ago. It is a complex mixture of organic compounds, including carbon, hydrogen, oxygen, nitrogen, and sulfur. Coal is used to generate electricity, heat homes and businesses, and produce coke, a fuel used in blast furnaces to make steel. The process of making coke from coal involves heating the coal in a coke oven in the absence of air. This process drives off the volatile matter in the coal, leaving behind a solid, porous material called coke. Coke is a valuable fuel because it burns hotter and cleaner than coal. Types of coal and rank Proximate and Ultimate Analysis Proximate and ultimate analysis are two methods used to characterize coal and coke. Proximate analysis measures the following properties of coal and coke: Moisture content: The amount of water in the coal or coke. Ash content : The amount of non-combustible material in the coal or coke. Volatile matter : ...
