Introducing the Cutting-Edge Vertical Shaft Lime Kiln Production Line: A Groundbreaking 100-500 Tpd Solution!
In-Depth Product Overview
The vertical shaft lime kiln is an impressive and carefully crafted vertical marvel, dedicated to the refined art of lime burning. This state-of-the-art steel cylindrical masterpiece capitalizes on the advanced heat exchange principle, where the natural gravitational flow of raw materials elegantly aligns with the rising hot gases, resulting in lime of unmatched quality and purity.stone. With precision and care, materials are delivered through the top and withdrawn from the bottom post-calcination, as the kiln's temperature gradient expertly crafts three unique operational zones. It boasts a strategically engineered division into the preheat zone, the calcination zone, and the cooling zone..
In the preheat zone, materials are strategically warmed by flue gases; within the calcination zone, they undergo calcination, powered by the intense heat from fuel combustion; in the cooling zone, the hot calcined materials transfer their heat to the incoming cool air, effectively cooling themselves while providing preheated air for fuel combustion in the calcination zone. This meticulously designed system assures a seamless and complete calcination process. It incorporates cutting-edge technology to maximize the use of cost-effective energy sources, transforming environmentally harmful gases such as converter gas, blast furnace gas, and calcium carbide furnace tail gas into valuable energy.
Key Advantages of Our Product
1) Superior Energy Efficiency: After utilizing the heat from the calcination process, the remaining hot flue gas effectively preheats incoming material, optimizing energy efficiency and significantly reducing output flue gas temperature to a remarkably low range of 170~300ºC.
2) The kiln's lining is composed of four layers of robust refractory materials, offering excellent thermal insulation. The kiln shell maintains a temperature approximately 60°C above ambient, thereby reducing excessive energy consumption.
3) Typically, the refractory materials feature a long lifespan of 6 to 10 years, ensuring durability and cost-effectiveness over time.
4) The kiln exhibits remarkable fuel flexibility. It seamlessly handles mixed fuels like lump coal and coke, high calorific gases including natural gas and coke oven gas, and alternative fuels such as converter gas, blast furnace gas, as well as lesser calorific fuels like coal gas and generator gas, showcasing impressive adaptability. Fuel oils such as heavy oil and diesel further elevate its versatility.
5) The innovative vertical shaft design, with its single bucket elevator and intelligently compact layout, optimizes space utilization.
6) Lowered investment requirements, our kiln offers a highly efficient streamlined steel structure with fewer machined parts, substantially reducing processing costs. The design simplifies installation, facilitating the effortless construction of refractory materials, ensuring seamless operational execution.
