Custom Lime Kiln Systems for Efficient 100-500 TPD Production
In-depth Product Introduction
The vertical shaft lime kiln stands as a formidable and intricately crafted vertical marvel, committed to the refined process of lime burning. This avant-garde cylindrical construction, crafted from robust steel, harnesses the sophisticated heat exchange principle, where the natural gravitational flow of raw materials perfectly synchronizes with the rising currents of hot gases, producing lime of the finest quality.stone. Under meticulous management, materials are introduced at the summit and retrieved from the base after calcination, with the kiln's strategic temperature gradient developing three distinct operational zones. It boasts a strategic partition into the preheat zone, the calcination zone, and the cooling zone..
In the preheat zone, materials draw upon the warmth of the flue gases; within the calcination zone, they experience calcination through the intense heat generated by fuel combustion; in the cooling zone, the hot calcined materials impart heat to the incoming cold air, effectively self-cooling while supplying preheated air to fuel combustion in the calcination zone. This holistic system guarantees a flawless and comprehensive calcination process. It seamlessly integrates cutting-edge technology to optimize the use of economical energy sources, transforming environmentally degradable gases like converter gas, blast furnace gas, and calcium carbide furnace tail gas into valuable energy.
Highlighted Key Advantages of the Product
1) Superior Energy Efficiency: After the calcination process benefits from the heat, the remaining hot flue gas efficiently preheats the incoming material, thereby maximizing energy efficiency and drastically lowering output flue gas temperature to an ultra-efficient range of 170~300ºC.
2) The kiln's lining consists of four layers of durable refractory materials, ensuring superb thermal insulation. The kiln shell maintains a temperature approximately 60°C above ambient, thereby significantly reducing unnecessary energy consumption.
3) Typically, the refractory materials boast an extended lifespan of 6 to 10 years, guaranteeing durability and long-term cost-effectiveness.
4) The kiln demonstrates exceptional fuel adaptability. It efficiently utilizes mixed fuels such as lump coal and coke, high calorific gases like natural gas and coke oven gas, and alternative fuels including converter gas, blast furnace gas, and lower calorific fuels such as coal gas and generator gas with remarkable flexibility. Fuel oils like heavy oil and diesel further enhance its versatility.
5) The strategic vertical shaft configuration, featuring a single bucket elevator and an intelligently compact layout, optimizes space usage.
6) Reduced investment requirements: Our kiln offers a highly efficient, streamlined steel structure with fewer machined components, significantly reducing processing costs. The design streamlines installation, ensuring seamless assembly of refractory materials and smooth operational performance.
