Lime kilns are used for the production of lime, a versatile chemical compound derived from limestone or calcium carbonate. Lime kilns are industrial furnaces designed to heat limestone at high temperatures, typically between 900 and 1200 degrees Celsius (1650 and 2200 degrees Fahrenheit). The process of heating limestone in lime kilns is known as calcination, which involves the decomposition of limestone to release carbon dioxide gas and produce lime.
LIME KILN APPLICATION
Construction and Building Materials: Lime is a key ingredient in the production of various construction and building materials. It is used in the manufacturing of cement, mortar, plaster, and concrete, where it acts as a binder and provides strength, durability, and workability to these materials.
Steel and Iron Production: Lime is utilized in steelmaking as a fluxing agent to remove impurities, such as silica, phosphorus, and sulfur, from the iron ore. It helps control the chemical composition and temperature during the steel refining process.
Environmental Applications: Lime plays a vital role in environmental applications. It is used in wastewater treatment plants to adjust the pH level, precipitate heavy metals, and remove impurities. Lime is also employed in flue gas desulfurization (FGD) systems to reduce sulfur dioxide emissions from power plants and industrial processes.
