A lime kiln is an environmentally friendly and energy-saving calcination device, primarily used to decompose limestone into calcium oxide. It is widely used in industries such as steel, calcium carbide, alumina, and refractory materials. Employing mechanized and automated technologies, it can utilize industrial waste gases such as coke oven gas and blast furnace gas as fuel, achieving energy recycling and pollution reduction.
Lime kilns are classified by fuel type into co-firing kilns (coke/coal) and gas-firing kilns (coal gas/natural gas), and by kiln type into vertical kilns and rotary kilns. The core process involves decomposing calcium carbonate at a high temperature of 850-1200℃, and is equipped with an automated control system for precise operation. The main structure includes the kiln body, material distribution device, and dust removal system. The dust removal device effectively treats sulfur-containing and dusty flue gas, meeting environmental emission standards. The equipment has strict requirements for raw materials; the calcium carbonate content of the limestone must be higher than 97%.
